Video cameras have traditionally been used for security surveillance of an area or location. Due to advancement of computing technologies along with improved storage devices and communication networks, cameras are being put to many uses supporting various applications. One such application is the surveillance over closed network circuits. For example, Closed-circuit Television (CCTV) cameras are in widespread usage for surveillance of a location and associated events. The CCTV cameras are deployed in homes, offices, shopping malls, busy markets, and public places for performing surveillance of thereof. The cameras are then only used for a specific home, work place, or location and the video recorded is stored and can only be viewed on site.
Additionally, a traditional neighborhood watch programs are implemented by having residents on a block or within a certain locality or neighborhood watch for strange vehicles, persons and other uncommon events in order to achieve a secure and safe environment of the residents thereof. Even then, residents generally have camera networks of their own for their own property for instances that are not captured by the neighborhood watch.
However, there are several shortcomings in the existing surveillance solutions. For example, the existing solutions employ individual cameras to monitor a particular location, which is limited by field of view of the camera. Individuals may also only be able to afford lower quality cameras. A camera having large field of view and higher quality image can monitor a larger area and retain greater details about the goings-on of the location, however, increased quality of cameras is expensive and cumbersome. As well, increasing the quantity of cameras for greater coverage on a property can be expensive.
Some existing solutions, instead of deploying cameras with large field of view, deploy multiple cameras at various locations within or around an area to be monitored. For example, in a large building, CCTV cameras are deployed at reception area, in the lobbies, in the restaurant, and at the gates of the building. Each of the CCTV cameras captures and transmits images or videos to a control room where the images or videos are displayed at multiple screens. Each CCTV camera has a corresponding display screen in the control room displaying images or videos in the field of view of that CCTV camera. However, even the deployment of multiple cameras in the existing surveillance solutions fails to provide satisfactory surveillance due to discrete nature of monitoring data including the captured images or videos.
Therefore, there is a need for providing effective surveillance and monitoring of a neighborhood or location.
Various exemplary embodiments are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings in which like reference numerals refer to similar elements and in which:
An apparatus, method and software for facilitating a network of cameras providing surveillance and one or more other services in a neighborhood are disclosed. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It would be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details or with an equivalent arrangement. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.
In one embodiment, many homes within a neighborhood have their own network of cameras as surveillance for their own homes. The addition of more cameras would make the surveillance of the occupant's home more complete and protect from more additional threats or at least, in order to better determine a perpetrator of crimes against the home and its occupants. In order to best do this, the present invention makes occupants, subscribers, this grants surveillance through the use of the neighbor's home surveillance cameras in addition to their own cameras. Each homes' cameras being on different networks makes this task more difficult, as well as, determining which cameras to use based on their field of view, e.g., cameras viewing the inside of a home would not be a part of this networking of neighborhood cameras. But the present invention provides a solution to this problem to create greater safety in numbers as well as address additional neighborhood issues, e.g., finding lost objects or notifying neighbors of potential dangers.

Similarly, the stitching of videos to generate a composite video may be achieved using any known proprietary or open source technique and/or algorithm.
The stitching module 205 may determine whether images captured by one camera are sequential to the images captured by the next camera. The stitching module 205 may determine a sequence of images or videos for generation of a composite image or composite video. In one embodiment, the sequence of images or videos may be based on the orientation information associated with the cameras 101. For example, an image or video captured by a camera facing main gate of a street may be placed before an image or video captured by a camera facing inside of the street in the sequence of the images or videos. In one embodiment, the sequence of images or videos may be based on the location information associated with the cameras 101. For example, an image or video captured by a camera installed on first house of the street may be placed before an image or video captured by a camera installed on a second house of the street in the sequence of the images or videos.
In one embodiment, the sequence of images or videos may be based on field of view information associated with the cameras 101. For example, an image or video captured by a camera having a larger field of view may be placed before an image or video captured by a camera having a smaller field of view in the sequence of the images or videos. Further, the field of view information may also include angular field of view and linear field of view information. In one embodiment, the sequence of images or videos may be determined based on a combination of the orientation information, the field of view information and the location information associated with the cameras 101.
In one embodiment, the stitching of images or videos may be based on the quality of images or video from each camera, with each camera providing a different level of definition and detail due to quality of the image or video recorded.
The object identification module 211 may be configured to identify objects in the neighborhood. For example, the object identification module 211 may identify lost pets or items as well as stolen vehicles in the neighborhood.
The object tracking module 209 may be configured to track one or more objects in the neighborhood. The object tracking module 209 may be configured to receive a request for tracking an object. The request for tracking the object may be received from an owner of the object such as pet or a vehicle. In one embodiment, the request may be received from a law enforcement agency to track stolen goods, such as a stolen vehicle. The object tracking module 209 may perform the tracking of the object based on a determination of presence information and movement information of the object. The presence information and the movement information may be determined based on a processing of one or more images, one or more videos, the composite image, and the composite video captured and/or generated by the network of cameras 101. In one embodiment, the location of an object may be determined based on the location of the camera which covers the field of view in which the object is seen at the moment. Further, the movement information of an object may be determined based on the images supplied by the network of cameras 101. In this way, a continuous tracking of an object in the neighborhood may be achieved.
The event determination module 207 may be configured to determine an event in the neighborhood. The event may be associated with identification and tracking of one or more objects. In one embodiment, the event may be identification of a lost pet or a stolen vehicle. In one embodiment, the event determination module 207 may also be configured to turn on and off surveillance cameras based on occupants being away from home or at home. In one embodiment, an event may include kids playing in the street or other large gatherings of persons, thus where the potential harm from danger increases, more definition and detail from the camera settings and more cameras may be initiated.
The user access module 213 may be configured to enable access of data stored in the video storage 123 and the network database 121 to users participating in the network of cameras.
The third party access module 215 may be configured to enable access of data stored in the video storage 123 and the network database 121 to users not participating in the network of cameras, i.e., third parties such as law enforcement or users of other networks of cameras.
The alert generation module 217 may be configured to generate an alert for an event in the neighborhood. For example, a stolen vehicle may be detected in the neighborhood, and an alert may be provided to a law enforcement agency, which may take an appropriate step based on the alert. In another example, a lost pet may be detected based on the images and videos associated with the neighborhood and an owner or security guard may be alerted about the location of the lost pet.
At step 303, the received one or more images and one more videos may be stitched to generate a composite image or a composite video at the networked camera platform 103. The stitching of images to generate a composite image may be achieved using any known proprietary or open source technique and/or algorithm. Similarly, the stitching of videos to generate a composite video may be achieved using any known proprietary or open source technique and/or algorithm.
At step 305, the composite image or the composite video may be made available to one or more users of the network. An access to the composite image or video may be provided to a user based on a subscription plan of the user. A variety of subscription plans may be offered to users from which a user can select one or more subscription plans as per his or her requirements. Some subscription plans may be priced higher than other subscription plans based on specific services provided under the subscription plans. For example, in one embodiment, a subscription plan providing access to high resolution images or videos may be priced higher than another subscription plan which provides access to low or medium resolution images or videos. A user may modify his or her subscription plan as per the requirements.
At step 307, the composite image or video and individual images or videos may be stored in the video storage 123. Data storage techniques may be utilized to provide required redundancy and efficiency in the system 100. Individual images may be stored separately from the composite images and selective access may be provided to a user. Similarly, individual videos may be stored separately from the composite videos and selective access may be provided to a user. In one embodiment, the individual and composite images may be stored separately from the individual and composite videos. In one embodiment, the video storage 123 may be external to the networked camera platform 103. In another embodiment, the video storage 123 may be internal and a part of the networked camera platform 103.
At step 401, it is determined whether to include a particular camera in the network of cameras. The determination may be based on the orientation information. For example, a camera facing a street may be included and a camera facing inside of a house may be excluded from the network of cameras. In one embodiment, the determination on inclusion of a camera may be based on location information associated with the camera. For example, a camera having a location corresponding to a first street may be included and another camera having a location corresponding to a second street may be excluded from the network of cameras. In one embodiment, the determination on inclusion of a camera may be based on a combination of the orientation information and the location information.
At step 403, a sequence of images or videos is determined for generation of a composite image or composite video. In one embodiment, the sequence of images or videos may be based on the orientation information associated with the cameras 101. For example, an image or video captured by a camera facing main gate of a street may be placed before an image or video captured by a camera facing inside of the street in the sequence of the images or videos. In one embodiment, the sequence of images or videos may be based on the location information associated with the cameras 101. For example, an image or video captured by a camera installed on first house of the street may be placed before an image or video captured by a camera installed on a second house of the street in the sequence of the images or videos. In one embodiment, the sequence of images or videos may be based on field of view information associated with the cameras 101. For example, an image or video captured by a camera having a larger field of view may be placed before an image or video captured by a camera having a smaller field of view in the sequence of the images or videos. Further, the field of view information may also include angular field of view and linear field of view. In one embodiment, the sequence of images or videos may be based on a combination of the orientation information, the field of view information and the location information associated with the cameras 101.
In one embodiment, the generation of a composite image or video may include camera quality in determining which images or video are central to the composition. Higher quality image or video will take priority over lower quality images or video in order to get the best representation of the real time surveillance of the neighborhood network. Additionally, in one embodiment, the quality used by each camera may be changed, increased or decreased as needed. For example, if a camera detects uncommon movement the quality can be jumped to its highest level quality and if nothing is going on it can be dropped to its lowest level quality.
At step 405, the orientation information, the field of view information, and the location information may be determined. In one embodiment, the determination of the orientation information may be based on image processing information. For example, the orientation of a camera may be determined based on an analysis of images or videos captured by that camera. Further, the orientation of the camera may also be determined based on analysis of audio data associated with the videos captured by that camera. For example, sound and voice patterns or signatures of the audio data may be compared with predetermined voice signatures of various events and objects to determine whether a camera is facing inside of a house or facing the street.
In one embodiment, the determination of the location information may be based on location sensor information. The location sensor may be based on Global Positioning System (GPS) unit included in a camera. The GPS unit may further be augmented with other units and specialized techniques may be applied to determine a micro location of a camera. Further, in one embodiment the field of view information may be determined based on the image processing information and the location sensor information. Further, in one embodiment, the determination of the orientation information, the field of view information, and the location information may be based on a combination of the image processing information, the location sensor information, and the micro-location information.
At step 501, a request may be received at the networked camera platform 103 for tracking an object. The request for tracking the object may be received from an owner of the object such as pet or a vehicle. In one embodiment, the request may be received from a law enforcement agency to track a stolen good such a stolen vehicle.
At step 503, the tracking of the object may be initiated. The tracking of the object may be based on a determination of presence information and movement information of the object. The presence information and the movement information may be determined based on a processing of one or more images, one or more videos, the composite image, and the composite video captured and/or generated by the network of cameras 101.
At step 505, an alert may be generated based on the tracking of the object. The alert may indicate the presence information and the movement information of the object in the neighborhood. The alert may be in the form of a text message, a graphical icon, an audio, a video or a combination thereof.
At step 507, access to data associated with the tracking of the object may be provided to a user other than the users participating in the network of cameras. The data associated with the tracking of the object may include but not limited to the composite image, the composite video, the one or more images, the one or more videos or a combination thereof.
Thus, the system 100 provides effective general surveillance of the neighborhood, law enforcement services, lost and found services, object identification and tracking services with the network of the cameras.
The computer system 800 may be coupled via the bus 801 to a display 811, such as a cathode ray tube (CRT), liquid crystal display, active matrix display, or plasma display, for displaying information to a computer user. An input device 813, such as a keyboard including alphanumeric and other keys, is coupled to the bus 801 for communicating information and command selections to the processor 803. Another type of user input device is a cursor control 815, such as a mouse, a trackball, or cursor direction keys, for communicating direction information and command selections to the processor 803 and for controlling cursor movement on the display 811.
According to an embodiment of the invention, the processes described herein are performed by the computer system 800, in response to the processor 803 executing an arrangement of instructions contained in main memory 805. Such instructions can be read into main memory 805 from another computer-readable medium, such as the storage device 809. Execution of the arrangement of instructions contained in main memory 805 causes the processor 803 to perform the process steps described herein. One or more processors in a multi-processing arrangement may also be employed to execute the instructions contained in main memory 805. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions to implement the embodiment of the invention. Thus, embodiments of the invention are not limited to any specific combination of hardware circuitry and software.
The computer system 800 also includes a communication interface 817 coupled to bus 801. The communication interface 817 provides a two-way data communication coupling to a network link 819 connected to a local network 821. For example, the communication interface 817 may be a digital subscriber line (DSL) card or modem, an integrated services digital network (ISDN) card, a cable modem, a telephone modem, or any other communication interface to provide a data communication connection to a corresponding type of communication line. As another example, communication interface 817 may be a local area network (LAN) card (e.g. for Ethernet™ or an Asynchronous Transfer Mode (ATM) network) to provide a data communication connection to a compatible LAN. Wireless links can also be implemented. In any such implementation, communication interface 817 sends and receives electrical, electromagnetic, or optical signals that carry digital data streams representing various types of information. Further, the communication interface 817 can include peripheral interface devices, such as a Universal Serial Bus (USB) interface, a PCMCIA (Personal Computer Memory Card International Association) interface, etc. Although a single communication interface 817 is depicted in
The network link 819 typically provides data communication through one or more networks to other data devices. For example, the network link 819 may provide a connection through local network 821 to a host computer 823, which has connectivity to a network 825 (e.g. a wide area network (WAN) or the global packet data communication network now commonly referred to as the “Internet”) or to data equipment operated by a service provider. The local network 821 and the network 825 both use electrical, electromagnetic, or optical signals to convey information and instructions. The signals through the various networks and the signals on the network link 819 and through the communication interface 817, which communicate digital data with the computer system 800, are exemplary forms of carrier waves bearing the information and instructions.
The computer system 800 can send messages and receive data, including program code, through the network(s), the network link 819, and the communication interface 817. In the Internet example, a server (not shown) might transmit requested code belonging to an application program for implementing an embodiment of the invention through the network 825, the local network 821 and the communication interface 817. The processor 803 may execute the transmitted code while being received and/or store the code in the storage device 809, or other non-volatile storage for later execution. In this manner, the computer system 800 may obtain application code in the form of a carrier wave.
The term “computer-readable medium” as used herein refers to any medium that participates in providing instructions to the processor 803 for execution. Such a medium may take many forms, including but not limited to non-volatile media, volatile media, and transmission media. Non-volatile media include, for example, optical or magnetic disks, such as the storage device 809. Volatile media include dynamic memory, such as main memory 805. Transmission media include coaxial cables, copper wire and fiber optics, including the wires that comprise the bus 801. Transmission media can also take the form of acoustic, optical, or electromagnetic waves, such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, CDRW, DVD, any other optical medium, punch cards, paper tape, optical mark sheets, any other physical medium with patterns of holes or other optically recognizable indicia, a RAM, a PROM, and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave, or any other medium from which a computer can read.
Various forms of computer-readable media may be involved in providing instructions to a processor for execution. For example, the instructions for carrying out at least part of the embodiments of the invention may initially be borne on a magnetic disk of a remote computer. In such a scenario, the remote computer loads the instructions into main memory and sends the instructions over a telephone line using a modem. A modem of a local computer system receives the data on the telephone line and uses an infrared transmitter to convert the data to an infrared signal and transmit the infrared signal to a portable computing device, such as a personal digital assistant (PDA) or a laptop. An infrared detector on the portable computing device receives the information and instructions borne by the infrared signal and places the data on a bus. The bus conveys the data to main memory, from which a processor retrieves and executes the instructions. The instructions received by main memory can optionally be stored on storage device either before or after execution by processor.
In one embodiment, the chip set 900 includes a communication mechanism such as a bus 901 for passing information among the components of the chip set 900. A processor 903 has connectivity to the bus 901 to execute instructions and process information stored in, for example, a memory 905. The processor 903 may include one or more processing cores with each core configured to perform independently. A multi-core processor enables multiprocessing within a single physical package. Examples of a multi-core processor include two, four, eight, or greater numbers of processing cores. Alternatively or in addition, the processor 903 may include one or more microprocessors configured in tandem via the bus 901 to enable independent execution of instructions, pipelining, and multithreading. The processor 903 may also be accompanied with one or more specialized components to perform certain processing functions and tasks such as one or more digital signal processors (DSP) 907, or one or more application-specific integrated circuits (ASIC) 909. A DSP 907 typically is configured to process real-world signals (e.g., sound) in real time independently of the processor 903. Similarly, an ASIC 909 can be configured to performed specialized functions not easily performed by a general purposed processor. Other specialized components to aid in performing the inventive functions described herein include one or more field programmable gate arrays (FPGA) (not shown), one or more controllers (not shown), or one or more other special-purpose computer chips.
The processor 903 and accompanying components have connectivity to the memory 905 via the bus 901. The memory 905 includes both dynamic memory (e.g., RAM, magnetic disk, writable optical disk, etc.) and static memory (e.g., ROM, CD-ROM, etc.) for storing executable instructions that when executed perform the inventive steps described herein to controlling a set-top box based on device events. The memory 905 also stores the data associated with or generated by the execution of the inventive steps.
While certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Accordingly, the invention is not limited to such embodiments, but rather to the broader scope of the presented claims and various obvious modifications and equivalent arrangements.
