The image recognition processor 106 can include or incorporate an image labeling or annotation tool (i.e., “labeling tool”). The labeling tool can be used to process and label the images for bounding box object detection and segmentation so that the image is readable by machines. In some embodiments, the labeling tool can utilize human assistance and in other embodiments the labeling tool can operate solely with machine learning or artificial intelligence processes. In some embodiments, different image labeling tools may be used for processing images of different image types (e.g., interior images, exterior images, etc.). Using the image labeling tools, the various objects in the provided image (e.g., user image 300, exterior image 1100, interior image 1700) can be labeled for specific purposes. In some embodiments, labeled objects can be selected for replacement by a computer graphic object (e.g., 2D sprite or 3D polygon), which can be moved on-screen and otherwise manipulated as a single entity, e.g., for purposes of event animation. In some embodiments, labeled objects may be classified into different types or categories of objects for different purposes. For example, in some embodiments, labeled objects can be categorized for properties relating to event animation, e.g., movable-type objects, bendable-type objects, breakable-type objects, waterproof-type objects, water damageable-type objects, etc. In other embodiments, labeled objects can be categorized for properties relating to inventory or damage assessment, e.g., table-type objects, chair-type objects, window-type objects, hanging art-type objects, TV/computer screen-type objects. Such classification may be performed by the image recognition processor 106 or by another processor, e.g., the system processor 102 or graphics animation processor 108. The image labeling tools can use known or future-developed detection techniques for detection of the object including, but not limited to, semantic, bounding box, key-point and cuboid techniques.
A seismic event database 112 is operably connected to the server 102, either via the communication network 104 or directly. The seismic event database 112 stores parametric seismic event data corresponding to one or more earthquakes or other seismic events. The parametric seismic event data can include, but is not limited to, values for the following parameters: event name, event date, event epicenter location, event focus (i.e., hypocenter) location, event duration, event magnitude, event PGA, event maximum shaking intensity (“SI”), event maximum ground amplitude, event mean ground amplitude, and event shaking frequency for each seismic event. The seismic events data in the seismic event database 112 may be actual historical earthquake data, “relocated” earthquake data (i.e., where the majority of the data corresponds to a historical earthquake, but the epicenter/hypocenter location is changed to a different location) or hypothetical earthquake data specified by a user or otherwise generated. In some embodiments, the seismic event database 112 can be located within the server 102 or one of the subsystems. In some embodiments, the seismic event database 112 can include data and/or values from public or private earthquake reporting agencies, such as the U.S. Geological Survey.
User devices 114, 115 can connect to the system 100 through the communication network 104. The user devices 114, 115 can be mobile devices such as mobile phones, tablets, laptop computers or they can be stationary devices such as desktop computers or smart appliances including, but not limited to, smart televisions. In some embodiments, aspects of the current system 100 may include downloadable software or “apps” resident on the user devices 114, 115 and/or non-downloadable software (e.g., “cloud based software”) that remains resident on the server 102 or other elements of the system 100 and is accessed by the user device 114 via a web browser or other network interface.
Using the user devices 114, 115, system users can upload images of actual property via the network 104 to the server 102. The images of actual property can be captured using a camera 116 on the first user device 114 or from images stored in memory 118, e.g., a computer memory, hard drive, flash drive or other data storage technology. The images can be video programs, audiovisual programs and/or single or multiple still photo images. User devices 114 can also transmit additional information to the server 102 regarding the images, including, but not limited to, the geographic location of the property in the images (either entered by the user as text, captured via GPS or wireless location information on the user device 114, or captured vis geotagging information on the image file), the address of the property in the images, the name and/or other contact information of the user, a desired parametric seismic event and/or desired seismic parameters to be used in creating a parametric seismic event. Desired seismic parameters can include strength of the seismic event, duration of the seismic event, etc. Each of the seismic parameters can be input on the user devices 114, 115 by any suitable means. For example, the seismic parameters can be input or selected using a predetermined list, a slider associated with different values of the seismic parameters, a knob, a number entry. The inputs can be physical components on the user device 114, 115 or virtual representations on a display 120 of the user device 114, 115.
The system 100 processes, using an image recognition processor 106, the received images and identifies one or more structures comprising the property. The system 100 retrieves parametric data regarding a designated seismic event from the seismic event database 112. The system 100 defines a key data pair corresponding to the specified geographic location and the designated seismic event. The system 100 determines key attributes relating the key data pair. The key attributes correlate to how the parametric seismic data changes for distant geographic locations (i.e., at a distance from the event). In some embodiments, the values of key attributes are determined based principles known in physics and/or geology including, but not limited to principles of seismic attenuation, resonant vibration and/or soil behavior factors. In some embodiments, the values of key attributes are determined based on seismic attenuation factors and the distance between the property and the event center. In some embodiments, the values of key attributes are determined based on resonant vibration factors, the shaking frequency of the event, and the mass and/or resonant frequency of structures. In some embodiments, the values of key attributes are determined based on soil behavior factors and the soil at the property location, the event center, and/or at intervening geological features. Some key attributes may vary in direct (i.e., linear) proportion to the distance between the geographic location of the property/structure and the seismic event center, whereas other key attributes may vary according to reciprocal square of distance, logarithmic decay of distance or other mathematical functions relating to the distance. In some embodiments, the values of key attributes are selected by a user. Other key attributes may vary depending on other factors such as intervening geological features rather than distance. The system 100 determines, using a computer such as the system processor 102, values of a deemed seismic action at the specified geographic location by modifying the parametric data for the designated seismic event using all relevant key attributes. In some embodiments, multiple sets of values of the key attributes are predetermined. In this case, the system processor 102 prepare a plurality of videos each combination of key attributes for each value of the key attributes.

The system 100 can further determine a respective deemed damage corresponding to each structure based on the deemed seismic action. The system 100 produces images showing an electronic representation the one or more structures comprising the property modified with respective electronic representations of the respective deemed damage.

In other embodiments, the structure attribute is correlated to a determined resonant frequency of the structure. In still other embodiments, the structure attribute is correlated to a construction material of the structure. Thus, structures built with shake-resistant materials or building methods would have a different structure attribute than structures built with shake-damage prone materials or building methods.

Summarizing some of the methods relating to Effects Modeling in accordance with additional aspects: Motion (shake) effects added to entire video image based on designated SI/PGA (i.e., speed and magnitude are appropriate for PGA). Damage effects applied based on polygon modeling, texture sampling and texture substitution. Object in video is selected. Object is digitized into original polygon model (shape) and sampled for original texture (color and pattern). Object's original polygon model is deformed to create damaged polygon model; amount of deformation is based on designated SI/PGA. Object's original texture is replaced by damaged texture comprising original texture interspersed with contrasting “feature texture” (e.g., can be specific to type of damage such as cracks, exposed lumber, missing shingles, etc.); proportion of feature texture mixed to original texture is based on designated SI/PGA. Damaged object image is formed from damaged polygon model covered with damaged texture. Original object image is then overlayed by damaged object image in video.

The image recognition processor 1906 can include or incorporate an image labeling or annotation tool (i.e., “labeling tool”). The labeling tool can be used to process and label the images for bounding box object detection and segmentation so that the image is readable by machines. In some embodiments, the labeling tool can utilize human assistance and in other embodiments the labeling tool can operate solely with machine learning or artificial intelligence processes. In some embodiments, different image labeling tools may be used for processing images of different image types (e.g., interior images, exterior images, etc.). Using the image labeling tools, the various objects in the provided image can be labeled for specific purposes. In some embodiments, labeled objects can be selected for replacement by a computer graphic object (e.g., 2D sprite or 3D polygon), which can be moved on-screen and otherwise manipulated as a single entity, e.g., for purposes of event animation. In some embodiments, labeled objects may be classified into different types or categories of objects for different purposes. For example, in some embodiments, labeled objects can be categorized for properties relating to event animation, e.g., movable-type objects, bendable-type objects, breakable-type objects, waterproof-type objects, water damageable-type objects, etc. In other embodiments, labeled objects can be categorized for properties relating to inventory or damage assessment, e.g., table-type objects, chair-type objects, window-type objects, door-type objects, hanging art-type objects, TV/computer screen-type objects, etc. Such classification may be performed by the image recognition processor 1906 or by another processor, e.g., the system processor 1902 or graphics animation processor 1908. The image labeling tools can use known or future-developed detection techniques for detection of the object including, but not limited to, semantic, bounding box, key-point and cuboid techniques.
A seismic event database 1912 is operably connected to the server 1902, either via the communication network 1904 or directly. The seismic event database 1912 stores parametric seismic event data corresponding to one or more earthquakes or other seismic events. The parametric seismic event data can include, but is not limited to, values for the following parameters: event name, event date, event epicenter location, event focus (i.e., hypocenter) location, event duration, event magnitude, event PGA, event maximum shaking intensity (“SI”), event maximum ground amplitude, event mean ground amplitude, and event shaking frequency for each seismic event. The seismic events data in the seismic event database 1912 may be actual historical earthquake data, “relocated” earthquake data (i.e., where the majority of the data corresponds to a historical earthquake, but the epicenter/hypocenter location is changed to a different location) or hypothetical earthquake data specified by a user or otherwise generated. In some embodiments, the seismic event database 1912 can be located within the server 1902 or one of the subsystems. In some embodiments, the seismic event database 1912 can include data and/or values from public or private earthquake reporting agencies, such as the U.S. Geological Survey.
User devices 1914, 1915 can connect to the system 1900 through the communication network 1904. The user devices 1914, 1915 can be mobile devices such as mobile phones, tablets, laptop computers or they can be stationary devices such as desktop computers or smart appliances including, but not limited to, smart televisions. In some embodiments, aspects of the current system 1900 may include downloadable software or “apps” resident on the user devices 1914, 1915 and/or non-downloadable software (e.g., “cloud based software”) that remains resident on the server 1902 or other elements of the system 1900 and is accessed by the user device 1914 via a web browser or other network interface.
Using the user devices 1914, 1915, system users can upload images of actual property via the network 1904 to the server 1902. The images of actual property can be captured using a camera 1916 on the first user device 1914 or from images stored in memory 1918, e.g., a computer memory, hard drive, flash drive or other data storage technology. The images can be video programs, audiovisual programs and/or single or multiple still photo images. User devices 1914 can also transmit additional information to the server 1902 regarding the images, including, but not limited to, the geographic location of the property in the images (either entered by the user as text, captured via GPS or wireless location information on the user device 1914, or captured vis geotagging information on the image file), the address of the property in the images, the name and/or other contact information of the user, a desired parametric seismic event and/or desired seismic parameters to be used in creating a parametric seismic event. Desired seismic parameters can include strength of the seismic event, duration of the seismic event, etc. Each of the seismic parameters can be input on the user devices 1914, 1915 by any suitable means. For example, the seismic parameters can be input or selected using a predetermined list, a slider associated with different values of the seismic parameters, a knob, a number entry. The inputs can be physical components on the user device 1914, 1915 or virtual representations on a display 1920 of the user device 1914, 1915.
The system 1900 processes, using an image recognition processor 1906, the received images and identifies one or more structures comprising the property. The system 1900 retrieves parametric data regarding a designated seismic event from the seismic event database 1912. The system 1900 defines a key data pair corresponding to the specified geographic location and the designated seismic event. The system 1900 determines key attributes relating the key data pair. The key attributes correlate to how the parametric seismic data changes for distant geographic locations (i.e., at a distance from the event). In some embodiments, the values of key attributes are determined based principles known in physics and/or geology including, but not limited to principles of seismic attenuation, resonant vibration and/or soil behavior factors. In some embodiments, the values of key attributes are determined based on seismic attenuation factors and the distance between the property and the event center. In some embodiments, the values of key attributes are determined based on resonant vibration factors, the shaking frequency of the event, and the mass and/or resonant frequency of structures. In some embodiments, the values of key attributes are determined based on soil behavior factors and the soil at the property location, the event center, and/or at intervening geological features. Some key attributes may vary in direct (i.e., linear) proportion to the distance between the geographic location of the property/structure and the seismic event center, whereas other key attributes may vary according to reciprocal square of distance, logarithmic decay of distance or other mathematical functions relating to the distance. In some embodiments, the values of key attributes are selected by a user. Other key attributes may vary depending on other factors such as intervening geological features rather than distance. The system 1900 determines, using a computer such as the system processor 1902, values of a deemed seismic action at the specified geographic location by modifying the parametric data for the designated seismic event using all relevant key attributes. In some embodiments, multiple sets of values of the key attributes are predetermined. In this case, the system processor 1902 prepares a plurality of videos each combination of key attributes for each value of the key attributes.
In certain embodiments, the images of actual property can be captured using a camera 1916 on the first user device 1914 or from images stored in memory 1918, e.g., a computer memory, hard drive, flash drive or other data storage technology. User devices 1914 can also store additional information regarding the images, including, but not limited to, the geographic location of the property in the images (either entered by the user as text, captured via GPS or wireless location information on the user device 1914, or captured vis geotagging information on the image file), the address of the property in the images, the name and/or other contact information of the user, a desired parametric seismic event and/or desired seismic parameters to be used in creating a parametric seismic event. Desired seismic parameters can include strength of the seismic event, duration of the seismic event, etc. Each of the seismic parameters can be input on the user devices 1914, 1915 by any suitable means. For example, the seismic parameters can be input or selected using a predetermined list, a slider associated with different values of the seismic parameters, a knob, a number entry. The inputs can be physical components on the user device 1914, 1915 or virtual representations on a display 1920 of the user device 1914, 1915.
The processor 1922 on the user devices 1914, 1915 can process the received images and identifies one or more structures comprising the property. The processor 1922 can retrieve parametric data regarding a designated seismic event from the seismic event database 1912 via the communication network 1904. The processor 1922 can define a key data pair corresponding to the specified geographic location and the designated seismic event. The processor 1922 can determine key attributes relating the key data pair. The key attributes correlate to how the parametric seismic data changes for distant geographic locations (i.e., at a distance from the event). In some embodiments, the values of key attributes are determined based principles known in physics and/or geology including, but not limited to principles of seismic attenuation, resonant vibration and/or soil behavior factors. In some embodiments, the values of key attributes are determined based on seismic attenuation factors and the distance between the property and the event center. In some embodiments, the values of key attributes are determined based on resonant vibration factors, the shaking frequency of the event, and the mass and/or resonant frequency of structures. In some embodiments, the values of key attributes are determined based on soil behavior factors and the soil at the property location, the event center, and/or at intervening geological features. Some key attributes may vary in direct (i.e., linear) proportion to the distance between the geographic location of the property/structure and the seismic event center, whereas other key attributes may vary according to reciprocal square of distance, logarithmic decay of distance or other mathematical functions relating to the distance. In some embodiments, the values of key attributes are selected by a user. Other key attributes may vary depending on other factors such as intervening geological features rather than distance. The processor 1922 can determine values of a deemed seismic action at the specified geographic location by modifying the parametric data for the designated seismic event using all relevant key attributes. In some embodiments, multiple sets of values of the key attributes are predetermined. In this case, the processor 1922 can prepare a plurality of videos each combination of key attributes for each value of the key attributes.
The user device 1914, 1915 can also include a storage device 1924. A memory and a persistent storage are examples of storage devices 1924, which represent any structure(s) capable of storing and facilitating retrieval of information (such as data, program code, and/or other suitable information on a temporary or permanent basis). The storage device 1924 may represent a random access memory or any other suitable volatile or non-volatile storage device(s). The storage device 1924 may contain one or more components or devices supporting longer-term storage of data, such as a read only memory, hard drive, Flash memory, or optical disc.
The storage device 1924 can also include an AR plane manager application 1926, an AR mesh manager application 1928, and an AR camera manager application 1930. The processor 1922 can run the AR plane manager application 1926, the AR mesh manager application 1928, and the AR camera manager application 1930 for display or an electronic representation of physical effects and property damage resulting frame a parametric natural disaster event.
The AR plane manager application 1926, run using the processor 1922, can extract AR planes from a scene. The AR planes can be 3D planes that can be defined by a position, an orientation, and bounds. The AR planes can be rendered on a display 1920. The AR planes can also be classified into categories, such as wall, floor, ceiling, door, window, seat, table, none, etc.
The AR mesh manager application 1928 can mesh the Lidar point cloud in an AR wrapper. For example, the AR wrapper can be AR Foundation provided by Unity on platforms such as Apple iOS, such as iOS system ARKIT for Visual Inertial Odometry and 3D meshing, and Google Android. The 3D mesh consists of vertices, triangle definitions, and surface normal, as shown in
The AR camera manager application 1930 can provide a tracked six degree of freedom pose of a camera 1916 at every frame. The AR camera manager application 1930 can extract a camera image and camera parameters at each frame for computer vision applications.
Although
Specifically, in some embodiments, the system for display of an electronic representation of physical effects and property damage resulting from a parametric earthquake event can be provided in a stand-alone mobile device such as, but not limited to, a mobile phone, tablet or similar consumer electronic device. In such embodiments, the user device 1914 itself incudes the processor 1922, display device 1920, input device (e.g., touch screen), camera 1916 (including optical cameras and, optionally, Lidar or other distance sensors), image storage 1918 and storage device 1924. In such mobile device-based embodiments, the device 1914 may also include an image recognition processor 1906, graphics animation processor 1908 and/or image rendering engine 1910 implemented in hardware or software on the mobile device instead of, or in addition to, processors accessed remotely through a network 1904 and server 1902. In such mobile device-based embodiments, the device 1914 may also include a seismic event database 1912 stored in the memory device instead of, or in addition to, a seismic event database accessible via the network.
As shown in the scene generation subprocess 2002 of
The processor 1922 can also operate the camera 1916 to capture the wall, ceiling or floor as an orientation of the user device 1914 is rotate and moved around the room. One or more sensors of the user device 1914 can capture details for determining a camera pose for the camera 1916 as each frame of the wall, ceiling or floor is captured. The camera pose can be saved along with the Lidar information or each could be stored separately with a respective time stamp to match.
The processor 1922 can create a network mesh covering a scanned scene in operation 2008. In some embodiments, the network mesh can be a triangular mesh. In some embodiments, the network mesh can be a point cloud. In some embodiments, each surface or point of the mesh is determined based on a distance and/or orientation from an initial reference point. In some embodiments, each surface of the mesh is determined based on a distance and/or orientation from one or more planes in the scene. The network mesh can be determined based on a combination of the Lidar and the camera pose. In certain embodiments, the camera can be used in combination with the camera pose and other sensors on the user device 1914 to create the network mesh. The network mesh can be formed using one or more shapes, such as a triangular mesh.
The processor 1922 can select a texture for an AR background in operation 2010. The texture can be based on an image of the scene captured by the camera 1916. The processor 1916 can analyze the image and determine a texture for the AR background. Different types of textures that can be selected could include color, pattern, etc. The AR background can have one or more textures that can be selected. In certain embodiments, the camera can process an image of a wall in a room and determine a color and pattern for the wall to be used for the texture of the AR background to simulate the color and pattern on the actual wall. Alternatively, the texture of the AR background can be preselected on a user device, selected at the time of mesh generation, or read from a default setting in the memory. While a texture close to the actual background of the scene is preferable in some embodiments, a texture that is different from the background can be chosen in some instances to more clearly distinguish the AR background from objects in the scene.
The processor 1922 can put the selected texture on the AR background in operation 2012. Once the texture is selected based on operation 2010, the processor 1922 can build a mesh for a point cloud or a mesh for a 3D depth image as triangle definitions. The selected texture can be viewed on the display 1920 overlaid as texture on the generated mesh. This mesh is virtually placed in the scene on top of the background currently captured by the camera 1916 of the user device 1914. A dimension (e.g., depth or distance from the camera) for the background captured from the camera 1916 can be determined and the selected texture can be implemented in front of or behind physical objects in the scene where the background may be not visible. Using the depth value associated with each pixel in the background, the generated mesh with the selected texture can be placed relative (in front of/behind) to the objects in the background. This can be used to selectively hide or show objects in the scene.
The processor 1922 can replace an actual object in the scene with a corresponding AR shape (i.e., AR object) and at a corresponding location in the scene in operation 2014. Objects in the scene can be identified in front of the background. Objects in the scene may include, but are not limited to, all types of furnishings and personal property within residence or building such as tables, chairs, sofas, lamps, cabinets, chests, desks, books, bookcases, shelves, beds, stoves, ovens, microwave ovens, dishes, cups, glasses, window curtains, window blinds, pictures, artwork, clocks, vases, rugs, carpets, televisions, radios, electronic equipment (collectively “furnishings”). In some embodiments, the objects in the scene can be identified by evaluating the previously-created mesh for specific predetermined patterns. Such predetermined patterns may include, but are not limited to, mesh contours, mesh contour borders, mesh flatness, mesh depth from background (e.g., distance in front of the wall), mesh orientation from background (e.g., angle to wall). Such predetermined patterns may be stored in the memory 1924 of the user device 1914. In some embodiments, identified objects in the scene may be classified into one or more categories of like objects. In some embodiments, the method may allow the user to confirm whether the classification of the identified object in the scene is correct. In some embodiments, the user may be able to edit the classification of an identified object. The processor 1922 can determine dimensions, orientation, and position within the scene for each detected object. The processor 1922 can use the dimensions of the object to create a corresponding AR shape and use the orientation and position within the scene for placing the AR shape as an overlay for the object in the display 1920. The AR shape can correspond to a 3D representation of the object. The processor 1922 can extract and layout an actual image of the object in operation 2016. The processor 1922 uses the camera 1916 to capture one or more fames and can identify the object in the image frame using the position information to identify the object scene. The portion of the image frame corresponding to the position of the object can be extracted. The extracted portion of the image can be overlaid on the 3D shape as a virtual representation of the object. The virtual representation of the object refers to the 3D shape with the actual image overlaid. The actual image and the 3D shape can be manipulated as the virtual representation of the object.
For example, in one embodiment the operation 2014 may evaluate the mesh, identify an object in a scene, and then classify the object into a category of like objects, e.g., a framed artwork (i.e., “picture”), by evaluating one or more predetermined patterns in the mesh such as: a) rectangular shape, i.e., mesh face bounded by four straight contour lines; b) flatness, i.e., mesh face at a substantially constant (i.e., within a preselected tolerance) distance above the underlying background plane; c) shallowness, i.e., average distance of face mesh above the underlying background plane is within a preselected tolerance; and/or d) frame presence, i.e., presence of a substantially constant (i.e., within a preselected tolerance) mesh color around the edges of the object. In some embodiments, the method may request user confirmation that the object is correctly classified as a framed artwork. Once the object is identified as framed artwork, the processor 1922 can use the dimensions of the actual object to create a corresponding AR shape with the characteristics of a framed artwork. The processor 1922 may use the orientation and position of the actual object within the scene for initially placing the AR framed artwork as an overlay for the actual framed artwork in the display 1920. In other words, the AR object, in this case a rectangle, may be initially displayed in front of the actual object in the view shown on the display 1920. The AR background may be modified to extend over the area coinciding with the actual object in the view shown on the display 1920. A photo image of the actual object may be applied as a texture to the surface of the AR shape. Thus, the AR shape may initially appear to the user as the same shape and position of the actual object. The processor 1922 can subsequently move the position of the AR framed artwork on the display screen 1920 and the image of the actual framed artwork will be obscured by the AR background so that it is not visible on the display screen. In this manner, the AR framed artwork will appear to the user observing the display screen 1920 to be the actual framed artwork, but the AR framed artwork can be manipulated by the processor 1922, e.g., to move, to oscillate, to fall and/or to break, despite the fact that the actual framed artwork remains unmoved and intact.
As shown in the simulation subprocess 2004 of
The processor 1922 can generate simulated (e.g., AR) seismic activity for the scene in operation 2020. The AR seismic activity can be shown to the user through the display 1920 of the user device 1914. The AR seismic activity can cause the portion of the AR background that is currently visible to shift in the frame of view on the display 1920. The edge of the background can be moved in and out of the frame in the display according to the one or more slider values.
The processor 1922 can display simulated (i.e., AR) cracks in the AR background shown on the display 1920 based on the slider value in operation 2022. In some embodiments, the processor 1922 can dynamically generate AR cracks in the AR background during a simulated seismic event, i.e., the cracks may grow in length or width as the seismic event progresses. In some embodiments, the processor 1922 can create a random number of AR cracks with varying paths, widths and/or depths based on the slider value in operation 2022. In some embodiments, the processor 1922 can generate AR cracks featuring parallax shading to give the cracks the appearance of three-dimensional depth and width based on the point of view. The selected intensity of the simulation can be a factor for the crack generation. The crack generation can also be determined based on an amount of time that has passed and/or a total time of the simulation. For example, additional cracks may be formed as the time of the simulated seismic activity continues. In addition, the dimension of the cracks can change over time and based on the factors of the seismic activity.
In operation 2024, the processor 1922 can move or manipulate an AR object (i.e., the virtual representation of the object) shown on the display 1920 during a simulation of a seismic event. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to an AR object based on one or more seismic characteristics input by the user or received from the system. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to an AR object based on the category of like objects into which the object has been classified. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to an AR object based on specified or sensed characteristics of the AR object including, but not limited to the object's mass, size and/or material. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to the AR object by applying a combination of the factors described above. Types of movements of the AR object that may be applied by the processor 1922 and shown on the display 1920 include, but are not limited to, translation, rotation, oscillation, falling and rolling. Type of manipulations of the AR object that may be applied by the processor 1922 and shown on the display 1920 include, but are not limited to, cracking, breaking, burning, leaking, sparking and soiling. For example, if an object in the scene is classified as a type of object that may be manipulated with “oscillation,” the processor 1922 can show the AR object swinging back and forth about a hinge point during the seismic event, and the magnitude of the swinging may be selected based on a seismic characteristic set by the slider value and/or on a characteristic of the object, such as its size. The virtual representation of the object can swing in relation to the background of the scene. In addition, if there are multiple AR objects in a scene, each virtual representation may swing independently from other virtual representations. In certain embodiments, a virtual representation of a picture frame can swing on a wall. While the virtual representation is swinging, the actual object is obscured by the wall set as a background in order for the swinging motion to not be disrupted by the actual picture frame.
In operation 2026, the processor 1922 can apply secondary manipulation types to the AR objects during a simulation of a seismic event. A secondary manipulation can be any manipulation that is applied only when predetermined conditions are met during a simulated seismic event. For example, if the AR object has a primary manipulation type of “oscillation” during a seismic event, the AR object may have a secondary manipulation type of “fall” if the magnitude of the shaking exceeds a preselected level, or if the shaking duration exceeds a preselected period. Thus, the processor 1922 will initially show the AR object oscillating (i.e., swinging) during a simulated seismic event, but will only show the AR object falling if the preselected conditions are met. If the preselected conditions are not met, the AR object will continue swinging according to the primary manipulation type. In some embodiments, the processor 1922 may show the virtual representation of the object fall to the floor based on a highest slider value in operation 2026. The virtual representation of the object can realistically drop to the floor using standard physics for a falling motion of the virtual representation. When the virtual representation of the object reaches another object or a ground level, the virtual representation can react with the other object or the ground level. For instance, a force could be applied to the other object based on the virtual representation dropping to the floor. The virtual representation can break or crack by the processor 1922 dividing the virtual representation into two or more part virtual representations. For instance, a picture frame can reach the ground level and cause a crack through the picture frame creating two separate parts of the picture frame. The two parts of the picture frame may operate independently for a remaining time of the simulation.
The virtual representation and background can be shaken independently. For example, a first picture frame can move independently from a second picture frame and a wall. The processor 1922 can create a set of parent coordinate transforms in an application, such as Unity. The parent transform can be an intermediate coordinate system between the world coordinate and children coordinates. The processor 1922 can set all sub-meshes from all regions that have a first face classification, such as “floor”, to a first transform (also referred to as a parent transform) and all sub-meshes from all regions that have a second classification, such as “wall”, to a second transform (also referred to as a child transform). The processor 1922 can set meshes that belong to a plane selected by a user as well as a plane with render cracks to a third transform. The processor 1922 can apply separate random shaking to each of the parent transforms in order to simulate differently classified virtual objects. Parent meshes ensure that a position of the sub meshes with respect to the parent transform remain constant. However, the position of the parent transform with respect to the world is allowed to change. This allows all meshes assigned to a common classification to move together.
The shaking and falling of objects, such as picture frames, can be performed by implementing Rigid body mechanics using a physic engine, such as but not limited to Unity Physics Engine, which is a standard game engine functionality provided by Unity. The standard game engine can simulate accelerations, connections, joints, and collisions between virtual objects. The selected wall plane and each picture frame can be assigned rigid body functionalities, which allows the objects to interact with each other in forms such as collisions, forces, constraints, and accelerations. The physics engine can provide functions that allow rigid bodies to relate to each other in a form of constraints. The physics engine can then iteratively solve multi-body simulation to give a position of the rigid bodies given the current position, constraints, and external forces/accelerations. The overall steps for this procedure can include (1) assigning rigid body functionalities to various identified AR objects in the scene, (2) adding constraints, such as joints, links, etc. between the instantiated virtual objects, and (3) adding acceleration or movement to one or more AR objects.
Although
The processor 1922 can scan planes in a scene in operation 2102. The planes can be converted to AR planes by the AR plane manager application 1926. The scanning of the planes can be performed by a Lidar sensor and a camera sensor. While the planes are scanned, other sensors on the user device 1914 can detect different information to be used with lidar information and camera information. Details of the AR plane can include position information, orientation information, bound information, etc. The planes can be classified by the AR plane manager application 1926. Non-limiting examples of classifications of the planes can include wall, floor, ceiling, door, window, none, etc.
The processor 1922 can select one or more planes to simulate an earthquake in operation 2104. The plane can be selected based on a current frame captured by the camera, selected by a user, etc. In certain embodiments, the planes can be selected based on a number of objects associated with the plane, between the camara and the plane, etc.
The processor 1922 can activate an AR mesh manager application 1928 in operation 2106. The AR mesh manager application 1928 can manage network meshes generated by the user device 1914. The AR mesh manager application 1928 can create, update, and/or remove virtual objects in response to the environment.
The processor 1922 can scan for meshes in operation 2108. The AR mesh manager application 1928 can be used to manage, store in memory, or perform operations on the meshes scanned by the processor. The meshes can be defined and/or categorized by the AR mesh manager application 1928 as belonging to various object classes such as but not limited to wall, floor, door, window, seat, none, etc. Meshes can be associated with objects in the scene in addition to a background. For example, meshes can be defined as part of a wall and part of one or more picture frames on the wall.
The processor 1922 can activate an AR camera manager application 1930 in operation 2110. The AR camera manager application 1930 can provide texture information and light estimation information. The AR camera manager application 1930 can also provide camera calibration parameters such as focal length, principle point, etc. The AR camera manager application 1930 can extract a camera image and camera parameters (such as camera pose parameters).
The processor 1922 can set global variables for the earthquake and also data extracted from the scanning process in operation 2114. The global variables can be received from a user selection on the display 1920 or input of the user device 1914. Non-limiting examples of the global variables can include seismic intensity, seismic duration, direction of seismic origin, etc. The global variables can also include variables associated with the selected plane, meshes that are not associated with the plane, meshes that are associated with the plane, virtual representations of object, etc.

In certain embodiments, the user device 914 can receive an input from a user for selecting a color of the selected plane, such as a tap on the display 1920 of the user device 1914. The AR camera manager application 1930 can provide a camera image and the processor 1922 can determine a location in the camera image corresponding to a location of the tap on the display 1920. The processor 1922 can determine a color at the location in the camera image to extract.

In certain embodiments, the processor 1922 can capture camera images including one or more picture frames.
The processor 1922 can determine that vertexes of the objects are clearly visible in the camera frame in operation 2126. Using the AR camera manager application 1930, the processor 1922 can identify each vertex of an object shown in the camera image. Camera images where the object is only partially visible can be skipped or used for clearly identified vertexes.

The AR wall plane that was selected during the plane scan process provides information such as plane position and orientation, plane boundaries in a plane space coordinate, and a 3D parametric plane equation [a, b, c, d] such that ax+by +cz+d=0 for all 3D points [x, y, z] that lie on the plane.
Using this information, the processor 1922 to perform operation 2112 uses a function to separate mesh points from belonging to a room plane and not belonging to the room plane, depending on whether the points satisfy the following conditions. (1) Points can be at most 0.1 m from a plane surface. Therefore, the at most absolute value of distance of a point [x1, y1, z1] to plane [a, b, c, d] is less than 0.1 m. (2) The point, lies within the plane boundaries to check if a point lies inside the plane boundaries. First transform the point from world space to plane space. Let x_W=[x1, x2, x3] be the point in world space and x_P=[xp1, xp2, xp3] be the point in plane space, R_p be the rotation matrix of the plane in world space, and P=[P1, P2, P3] be the position of the plane in world coordinates. Then the transformation shown in equation 1 holds and the inverse transformation is shown in equation 2.
x_W=R_p*x_P+P (1)
x_P=Inverse(R_p)*(x_W−P) (2)
(3) The processor 1922 can check whether the point in plane space x_P lies inside the boundaries of the plane. The y coordinate of the point can be dropped in order to obtain a corresponding 2D coordinate of the point in the plane space. i.e. x_P=[xp1, xp2, xp3] [xp1, xp3] in the 2D plane space, since the normal of the plane is the local y axis. (4) Finally to find out whether the point x_P belongs to the plane or outside the plane, the processor 1922 can compute the Winding Number for the points. If the winding number of the point does not equal to 0, then the point lies inside the plane boundaries. If the winding number of the point equals 0, the point lies outside the plane boundaries.

The processor 1922 can use a modified version of the union find algorithm with path optimization to determine the bounds 2306 of the disjointed meshes. The union find algorithm was originally designed to solve Kruskal's minimum spanning tree algorithm. The main goal of the union find algorithm is to have an efficient method of extracting and storing disjoint sets of nodes in a tree. The processor 1922 can find the disjoined meshes 2306 of vertices inside a mesh that belongs to the class “none”. As a non-limiting example, two picture frames exist inside of a single Mesh definition and need to be separated into two sub-meshes. The processor 1922 can use union operation to group two nodes into a single group and a find operation to find a parent of the group to which a node belongs to. This method can be adapted by assigning nodes to each vertex 2204-2210 in the mesh as a node and use the triangle definitions as union operations as shown in

The crack creation algorithm 2400 can utilize UV mapping 2402 to project the shader algorithm 2404 onto the chosen mesh. The UV mapping algorithm 2402 is described in greater detail in
The crack creation algorithm 2400 can utilize a mesh 2408 and a camera image 2410 to form pseudo 3D cracks on a plane. The crack creation algorithm 2400 can obtain mesh information such as UV coordinates and normal (x, y, z) vectors 2412 from the chosen mesh 2408. The camera image 2410 can include other details, such as camera pose information, that can be used to determine a view direction 2414 that is applied in the parallax occlusion mapping (POM) pass.
Voronoi noise is a noise function that utilizes distance functions between tiled points to obtain consistent cell like boundaries and spaces. To create a randomized domain of the Voronoi noise, the Voronoi noise pass algorithm 2405 can choose a random seed that connects to multiple randomizers. For example, the random seed can be chosen based on a time in the application. The randomizers can take a standardized UV input (linear gradient from 0-1 on x and y axis) and offset/scale the standard UV coordinates (0-1) randomly in order to generate different variations of noise for displacement. To obtain more vertical or horizontal cracks, the scaling of the UV coordinates can be adjusted separately. These UV values are plugged into two Voronoi noise generation subshaders, a subshader used for the U values 2504 (X-axis) and a subshader used for the V values 2506 (Y-axis). The two subshaders can be centered around 0 (−0.5 to 0.5) and combined into a single image consisting of U displacement on a red channel and V displacement on a green channel. The processor 1922 can use a multiply value to scale a displacement and/or distortion amount to be applied to the main Voronoi generation. The displacement/distortion amount can be added to an initial UV coordinate of the mesh geometry in a process known as domain warping. This warped UV space is then plugged into a final Voronoi subshader as the UV input. The processor 1922 can clamp the output using a smoothstep function to create sharp cell-like edges. This is saved into the memory via a custom render texture feature from Unity.
The custom render texture algorithm 2418 can allow an output of a shader to be saved into a texture and passed to various locations with Unity and allow for multiple passes. Within the crack plane creation script 2400, the Voronoi depth shader can be called with desired parameters to render into a texture via the custom render texture algorithm 2418.
The texture from the custom render texture algorithm 2418 can be used as an input to the parallax occlusion mapping (POM) pass algorithm 2406. The POM pass algorithm 2406 can apply shader to a mesh material 2416 as a final output to be shown with the display.

The processor 1922 can hold the UV blocks 2502 as a steady size. Therefore, a number of UV blocks 2502 is proportional to a size of the wall and, as the wall size increases, more UV blocks 2502 are utilized. UV blocks 2502 can be normalized between 0 and 1 in order to keep a constant aspect ratio. To normalize, an absolute value of the minimum value for the U value 2504 and V value 2506 to the actual values of the U value 2504 and the V value 2506 for each UV block 2502. The actual values of the U value 2504 and the V value 2506 for each UV block 2502 can be divided by a maximum value between the U values 2504 and the V values 2506. For example, the maximum value for the U value 2504 is 3.0 and for the V value 2506 is 2.0, which means the maximum value used to divide with is 3.0 resulting in a normalized UV table 2508 of normalized UV blocks 2510.

The Voronoi noise pass algorithm 2405 can generate a usable seamless distance function by searching neighboring cells 2610. The processor 1922 can calculate a distance from each pixel to a nearest point either in a respective cell or a neighboring cell.

The user device 2704 can include a display 2720, one or more sensors 2722 (e.g., optical camera, time of flight camera, etc.), and one or more physical inputs 2724 (e.g., buttons, switches, etc.). The user device 2704 can use a scan area 2723 one or more sensors 2722 to scan the scene 2702 and detect the background (e.g., wall 2706 and floor 2708) and objects (a window 2710, a first picture 2712, a second picture 2714, a chair 2716, and a rug 2718). The user device 2704 can create virtual or AR representations of the scene 2702 and present representations on the display 2720.

The shaking effect 2746 can be applied equally to the AR backgrounds or can be applied stronger or weaker to the specific AR backgrounds. The shaking effect 2746 applied to the AR background can be additionally applied to each of the AR objects in a manner of equal characteristics or reduced effectiveness characteristics. The reduced effectiveness characteristics can include lower shaking intensity transferred from the background, lower resistance (increased duration of shaking), etc. An amount of the vibration for the AR background or AR object can be controlled based on the input 2744 to the seismic attribute control 2740.
The display 2720 can apply a cracking effect 2748 on an AR background or an AR object, such as the AR wall 2726. The cracking effect 2748 can cause a 3D crack to form in the AR background. The 3D crack can be viewed from different angles to show a depth to the 3D crack. The cracking effect 2748 can include a 3D crack that extends from a first AR background to a second AR background. For example, the cracking effect 2748 can begin on the AR wall 2726 and extend to an AR ceiling, an AR second wall, and/or the AR floor 2728. A 3D crack on an AR background, such as the AR wall 2726, can extend behind and hidden an AR object to continue extending past the AR object in view on the display 2720. A size and growth rate for the 3D crack on the AR background or AR object can be controlled based on the input 2744 to the seismic attribute control 2740.
The display 2720 can apply a swinging effect 2750 to an AR object, such as the AR first picture 2732. The swinging effect 2750 can cause the AR object to shake similarly to the AR background contacting the AR object due to a fixed pendulum that the swinging occurs about. The swinging effect 2750 on the AR object can include a translation component equal to the vibration or shaking effect 2746 of the AR background. A swing rate for the swinging of AR object can be controlled based on the input 2744 to the seismic attribute control 2740.
The display 2720 can apply a falling effect 2752 to an AR object, such as the AR second picture 2734. The falling effect 2752 can move the AR object separately from the AR background and other AR objects. The falling effect 2752 can be based on gravity for controlling a falling rate and/or a falling speed. The falling effect 2752 can use an estimated or determined weight of the AR object to determine a force that could be applied to other AR objects and/or AR backgrounds. A timing for the falling of AR object can be controlled based on the input 2744 to the seismic attribute control 2740.
In certain embodiments, a secondary effect can be applied to an AR object, such as the AR second picture 2734. For example, a falling effect on an AR object causes the AR object to forcefully contact an AR background, such as the AR floor 2728, or another AR object, such as the AR chair 2736. A secondary effect of the falling effect could be a breaking effect 2754. The display can apply the breaking effect 2754 to the AR object, such as the AR second picture 2734. Other examples of secondary effects can include, a bouncing effect, a ricochet effect, a merge effect, striking effect, etc.
The breaking effect 2754 can cause the AR object to split into multiple AR partial objects. Each of the multiple AR partial objects can be smaller than the AR object before the split. In certain embodiments, the multiple AR partial objects can collectively be approximately equal to the broken AR object. An amount of AR partial objects can be based on an original size of an AR object, a force applied to the AR object during simulation from one or more other AR effects, etc.
A shatter effect 2756 can cause an AR object to have multiple AR partial objects splits from a main AR object, such as AR window 2730 or an AR mirror. The shatter effect 2756 can be a primary effect from the seismic damage or a secondary effect from another AR object forcefully interacting with the original AR object. For example, the AR window 2730 can shatter due directly to the vibrations from a seismic event or from an AR object, such as the AR second painting 2734 or generation of a random AR object, such as an AR branch of a tree, an AR power line, etc., falling through the AR object, such as AR window 2730.

The user can be presented an input, such as a slider, to control a seismic characteristic, such as a seismic intensity. The slider values can be controls for a parameter or attribute of the seismic activity. For example, the slider can control an intensity, a time period, etc. Additional parameters or attributes of the seismic activity not controlled by a slider can have values entered prior to the simulation or read from a memory 1918. The processor 1922 can show a slider or other mechanism for selecting the parameter value or attribute of the seismic activity on the display 1920. In certain embodiments, the slider can control a current intensity and seismic activity would continuously occur at the selected current intensity until the current intensity is set to zero on the slider. In some embodiments, a touch-screen or physical buttons, voice commands or other inputs can be used for entering parameters or attributes of the seismic activity instead of, or in addition to, the slider.
The processor 1922 can display seismic effects based on the seismic characteristics in operation 2912. The processor 1922 can generate simulated (e.g., AR) seismic activity for the scene in operation 2020. The AR seismic activity can be shown to the user through the display 1920 of the user device 1914. The AR seismic activity can cause the portion of the AR background that is currently visible to shift in the frame of view on the display 1920. The edge of the background can be moved in and out of the frame in the display according to the one or more slider values.
The processor 1922 can display simulated (i.e., AR) cracks in the AR background shown on the display 1920 based on the slider value in operation 2022. In some embodiments, the processor 1922 can dynamically generate AR cracks in the AR background during a simulated seismic event, i.e., the cracks may grow in length or width as the seismic event progresses. In some embodiments, the processor 1922 can create a random number of AR cracks with varying paths, widths and/or depths based on the slider value in operation 2022. In some embodiments, the processor 1922 can generate AR cracks featuring parallax shading to give the cracks the appearance of three-dimensional depth and width based on the point of view. The selected intensity of the of the simulation can be a factor for the crack generation. The crack generation can also be determined based on an amount of time that has passed and/or a total time of the simulation. For example, additional cracks may be formed as the time of the simulated seismic activity continues. In addition, the dimension of the cracks can change over time and based on the factors of the seismic activity.
In operation 2024, the processor 1922 can move or manipulate an AR object (i.e., the virtual representation of the object) shown on the display 1920 during a simulation of a seismic event. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to an AR object based on one or more seismic characteristics input by the user or received from the system. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to an AR object based on the category of like objects into which the object has been classified. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to an AR object based on specified or sensed characteristics of the AR object including, but not limited to the object's mass, size and/or material. In some embodiments, the processor 1922 may determine the type of a movement or a manipulation to be applied to the AR object by applying a combination of the factors described above. Types of movements of the AR object that may be applied by the processor 1922 and shown on the display 1920 include, but are not limited to, translation, rotation, oscillation, falling and rolling. Type of manipulations of the AR object that may be applied by the processor 1922 and shown on the display 1920 include, but are not limited to, cracking, breaking, burning, leaking, sparking and soiling. For example, if an object in the scene is classified as a type of object that may be manipulated with “oscillation,” the processor 1922 can show the AR object swinging back and forth about a hinge point during the seismic event, and the magnitude of the swinging may be selected based on a seismic characteristic set by the slider value and/or on a characteristic of the object, such as its size. The virtual representation of the object can swing in relation to the background of the scene. In addition, if there are multiple AR objects in a scene, each virtual representation may swing independently from other virtual representations. In certain embodiments, a virtual representation of a picture frame can swing on a wall. While the virtual representation is swinging, the actual object is obscured by the wall set as a background in order for the swinging motion to not be disrupted by the actual picture frame.
In operation 2026, the processor 1922 can apply secondary manipulation types to the AR objects during a simulation of a seismic event. A secondary manipulation can be any manipulation that is applied only when predetermined conditions are met during a simulated seismic event. For example, if the AR object has a primary manipulation type of “oscillation” during a seismic event, the AR object may have a secondary manipulation type of “fall” if the magnitude of the shaking exceeds a preselected level, or if the shaking duration exceeds a preselected period. Thus, the processor 1922 will initially show the AR object oscillating (i.e., swinging) during a simulated seismic event, but will only show the AR object falling if the preselected conditions are met. If the preselected conditions are not met, the AR object will continue swinging according to the primary manipulation type. In some embodiments, the processor 1922 may show the virtual representation of the object fall to the floor based on a highest slider value in operation 2026. The virtual representation of the object can realistically drop to the floor using standard physics for a falling motion of the virtual representation. When the virtual representation of the object reaches another object or a ground level, the virtual representation can react with the other object or the ground level. For instance, a force could be applied to the other object based on the virtual representation dropping to the floor. The virtual representation can break or crack by the processor 1922 dividing the virtual representation into two or more part virtual representations. For instance, a picture frame can reach the ground level and cause a crack through the picture frame creating two separate parts of the picture frame. The two parts of the picture frame may operate independently for a remaining time of the simulation.
The virtual representation and background can be shaken independently. For example, a first picture frame can move independently from a second picture frame and a wall. The processor 1922 can create a set of parent coordinate transforms in an application, such as Unity. The parent transform can be an intermediate coordinate system between the world coordinate and children coordinates. The processor 1922 can set all submeshes from all regions that have a first face classification, such as “floor”, to a first transform (also referred to as a parent transform) and all submeshes from all regions that have a second classification, such as “wall”, to a second transform (also referred to as a child transform). The processor 1922 can set meshes that belong to a plane selected by a User as well as a plane with render cracks to a third transform. The processor 1922 can apply separate random shaking to each of the parent transforms. Parent meshes ensure that a position of the sub meshes with respect to the parent transform remain constant. However, the position of the parent transform with respect to the world is allowed to change. This allows all meshes assigned to a common classification to move together.
The shaking and falling of objects, such as picture frames, can be performed by implementing Rigid body mechanics using a physic engine, such as a Unity Physics Engine. The selected wall plane and each picture frame can be assigned rigid body functionalities, which allows the objects to interact with each other in forms such as collisions, forces, constraints, and accelerations. The physics engine can provide functions that allow rigid bodies to relate to each other in a form of constraints. The physic engine can then iteratively solve multi-body simulation to give a next position of the rigid bodies given external forces. The overall steps for this procedure can include (1) assigning rigid bodies to a picture frame and a wall mesh, and (2) adding a revolute hinge joint constraint between picture frame and wall mesh.
The processor 1922 can determine a damage amount 2812 for the scene 2702 in operation 2914. The damage amount 2812 can be calculated as the simulation is in progress and/or after the simulation of seismic activity is completed. The damage amount 2812 can be calculated as a percentage, fraction, value, etc. The damage amount 2812 can be individually calculated for each AR object. The processor 1922 can utilize specific effects applied to an object and an intensity of the effect applied. For instance, an object that falls twice a distance as a similar object could be determined to have more damage. The processor 1922 can also determine a fragility of an object. For example, the processor 1922 can assign more damage to a vase falling an equal distance to a book.
