When large water vessels want to set anchor at a port dock, the process can be long and involves several stages. Before the final stages in such a process are reached, large water vessels need to make sure that they are not approaching the port dock too quickly. The frequency of incidents of large water vessels coming in too fast and hitting the port dock is alarming. When a large water vessel hits a dock unintentionally (or otherwise) it becomes a serious hazard that may result in human harm and casualties, disruptions to businesses and shipping customers, and also damages (e.g. fixed infrastructure damage, water vessel damages, etcetera) the repairs of which may result in very large amounts of money having to be spent.
In the accompanying figures similar or the same reference numerals may be repeated to indicate corresponding or analogous elements. These figures, together with the detailed description, below are incorporated in and form part of the specification and serve to further illustrate various embodiments of concepts that include the claimed invention, and to explain various principles and advantages of those embodiments.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help improve understanding of embodiments of the present disclosure.
The apparatus and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
According to one example embodiment, there is provided a computer-implemented method that includes initially detecting that a water vessel, having a mass and movable over a body of water, is present as a foreground object within at least one Field Of View (FOV) of a respective at least one camera. The body of water is a background object occupying a first region of the FOV. The computer-implemented method also includes carrying out analytics processing on at least one image that includes the water vessel, captured by the camera, to make an analytics-based estimation of the mass of the water vessel. The computer-implemented method also includes defining, based at least in part on the analytics-based estimation of the mass of the water vessel, vessel-specific boundaries of second and third regions that are sub-regions of the first region. The third region corresponds to a part of the body of water that is closer to a protected structure than the second region, and the protected structure is located at or physically connected to land abutting the body of water. The computer-implemented method also includes determining, by analytics and after the defining of the boundaries, that the water vessel has moved from the second region to the third region. The computer-implemented method also includes changing (responsive to the determining) security monitoring of the water vessel, within a security system, from a first monitoring mode to a second monitoring mode. The second monitoring mode is more sensitive than the first monitoring mode in relation to at least one of a measured velocity of the water vessel and a travel path of the water vessel being a conditionally defined trigger for at least one analytics-based alarm within the security system.
According to yet another example embodiment, there is provided a security system that includes at least one camera configured to capture images that include a water vessel. The security system also includes at least one processor communicatively coupled to the at least one camera. The at least one processor is configured to carry out a method that includes initially detecting that the water vessel, having a mass and movable over a body of water, is present as a foreground object within at least one FOV of the respective at least one camera. The body of water is a background object occupying a first region of the FOV. The method performable by the at least one processor also includes carrying out analytics processing on at least one image of the images to make an analytics-based estimation of the mass of the water vessel. The method performable by the at least one processor also includes defining, based at least in part on the analytics-based estimation of the mass of the water vessel, vessel-specific boundaries of second and third regions that are sub-regions of the first region. The third region corresponds to a part of the body of water that is closer to a protected structure than the second region, and the protected structure is located at or physically connected to land abutting the body of water. The method performable by the at least one processor also includes determining, by analytics and after the defining of the boundaries, that the water vessel has moved from the second region to the third region. The method performable by the at least one processor also includes, changing (responsive to the determining) security monitoring of the water vessel, within the security system, from a first monitoring mode to a second monitoring mode. The second monitoring mode is more sensitive than the first monitoring mode in relation to at least one of a measured velocity of the water vessel and a travel path of the water vessel being a conditionally defined trigger for at least one analytics-based alarm within the security system.
Each of the above-mentioned embodiments will be discussed in more detail below, starting with example system and device architectures of the system in which the embodiments may be practiced, followed by an illustration of processing blocks for achieving an improved technical method, system and computer program product for dynamically sizing security monitoring regions.

It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. The methods and processes set forth herein need not, in some embodiments, be performed in the exact sequence as shown and likewise various blocks may be performed in parallel rather than in sequence. Accordingly, the elements of methods and processes are referred to herein as “blocks” rather than “steps.”
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instructions which implement the function/act specified in the flowchart and/or block diagram block or blocks.

It is contemplated that any part of any aspect or embodiment discussed in this specification can be implemented or combined with any part of any other aspect or embodiment discussed in this specification.
The term “object” as used herein is understood to have the same meaning as would normally be given by one skilled in the art of video analytics, and examples of objects may include foreground objects (i.e. humans, vehicles, animals, and other objects that are substantially non-stationary). Moreover, examples of objects may also include background objects (i.e. buildings, stationary signs, identifiable parts of a scene that are not foreground objects, etcetera).
Further advantages and features consistent with this disclosure will be set forth in the following detailed description, with reference to the figures.

Continuing on,
In some example embodiments, the electronic computing device 104 is a personal computer system; however in other example embodiments the electronic computing device 104 is a selected one or more of the following: a handheld device such as, for example, a tablet, a phablet, a smart phone or a personal digital assistant (PDA); a laptop computer; a smart television; a two-way radio; marine communications device; and other suitable devices. With respect to the server system 108, this could comprise a single physical machine or multiple physical machines. It will be understood that the server system 108 need not be contained within a single chassis, nor necessarily will there be a single location for the server system 108. As will be appreciated by those skilled in the art, at least some of the functionality of the server system 108 can be implemented within the electronic computing device 104 rather than within the server system 108.
The electronic computing device 104 communicates with the server system 108 through one or more networks. These networks can include the Internet, or one or more other public/private networks coupled together by network switches or other communication elements. The network(s) could be of the form of, for example, client-server networks, peer-to-peer networks, etc. Data connections between the electronic computing device 104 and the server system 108 can be any number of known arrangements for accessing a data communications network, such as, for example, dial-up Serial Line Interface Protocol/Point-to-Point Protocol (SLIP/PPP), Integrated Services Digital Network (ISDN), dedicated lease line service, broadband (e.g. cable) access, Digital Subscriber Line (DSL), Asynchronous Transfer Mode (ATM), Frame Relay, or other known access techniques (for example, radio frequency (RF) links). In at least one example embodiment, the electronic computing device 104 and the server system 108 are within the same Local Area Network (LAN). In some examples, the electronic computing device 104 communicates directly or indirectly with other parts of security monitoring system 100 besides the server system 108.

The electronic computing device 104 may also include an operating system, communications related application(s), and various software applications (usable by the processor of the electronic computing device 104) and stored in the non-volatile storage of the electronic computing device 104. This non-volatile storage may be, for example, one or more hard disks, solid state drives, or some other suitable form of computer readable medium that retains recorded information after the electronic computing device 104 is turned off. Also, as appreciated by those skilled in the art, the operating system and other applications, or parts thereof, may be temporarily loaded into a volatile store such as the RAM of the electronic computing device 104.
Referring once again to
The server system 108 also includes a terminal operating system 193, the functionality for which will vary depending on the requirements of the port facility that the terminal operating system 193 supports. In at least some examples, the terminal operating system 193 facilitates the reading, writing, erasing and/or modifying of data related to operations at the port facility, including one or more of the following: vessel arrival and departure data, data related to the status of goods, data related to locations, and data related to machines within the port facility.
The server system 108 also includes server-side analytics module(s) 194 which can include, in some examples, any suitable one of known commercially available software that carry out computer vision related functions (complementary to any analytics performed in the cameras) as understood by a person of skill in the art. The server-side analytics module(s) 194 can also optionally include software for carrying out analytics that operate on some sensor-generated data other than video/images, including but not limited to audio analytics that may, for example, extract data from data-over-sound, convert spoken words into text, carry out audio emotion recognition, etc.
The server system 108 also includes a number of other software components 176. These other software components will vary depending on the requirements of the server system 108 within the overall system. As just one example, the other software components 176 might include special test and debugging software, or software to facilitate version updating of modules within the server system 108. The other software components 176 may also include one or more server-side modules that provide cooperative counterpart functionality to one or more communications related application(s) that run on one or more of the electronic computing devices 1041-104M.
Regarding the at least one storage device 190, this comprises, for example, one or more databases 191 which may facilitate the organized storing of recorded video, images and other data (such as, for example, data that one might expect to be stored and maintained in a marine port facility including one or more of the following: vessel arrival and departure data, data related to the status of goods, data related to locations and machines for the port facility, etcetera) in accordance with example embodiments. The one or more databases 191 may also contain metadata related to, for example, the recorded video and/or images that are storable within one or more storages. The one or more databases 191 may also optionally contain other types of metadata besides video/image metadata. Examples of metadata other than video/image metadata, that may be stored in the one or more databases 191, include audio metadata, Global Positioning System (GPS) location metadata, etcetera.

More details of the camera 103 are shown in
The image sensor 309 may be operable to capture light in one or more frequency ranges. For example, the image sensor 309 may be operable to capture light in a range that substantially corresponds to the visible light frequency range. In other examples, the image sensor 309 may be operable to capture light outside the visible light range, such as in the infrared and/or ultraviolet range. In other examples, the camera 103 may have characteristics such that it may be described as being a “multi-sensor” type of camera, such that the camera 103 includes pairs of two or more sensors that are operable to capture light in different and/or same frequency ranges.
The camera 103 may be a dedicated camera. It will be understood that a dedicated camera herein refers to a camera whose principal features are to capture images and/or video. In some example embodiments, the dedicated camera may perform functions associated with the captured images or video, such as but not limited to processing the video/image data produced by it or by another camera. For example, the dedicated camera may optionally be a security video camera, such as any one of a pan-tilt-zoom video camera, dome video camera, in-ceiling video camera, box video camera, and bullet video camera.
Additionally, or alternatively, the camera 103 may include an embedded camera. It will be understood that an embedded camera herein refers to a camera that is embedded within a device that is operational to perform functions that are unrelated to the captured image or video. For example, the embedded camera may be a camera found on any one of a laptop, tablet, drone device, physical access control device, etc.
The camera 103 includes one or more processors 313, one or more analytics modules 319, and one or more memory devices 315 coupled to the processors and one or more network interfaces. Regarding the analytics module 319, this generates metadata outputted to the server system 108. In the case of video, the metadata can include, for example, records which describe various detections of objects such as, for instance, pixel locations for the detected object in respect of a first record and a last record for the camera within which the respective metadata is being generated.
Regarding the memory device 315 within the camera 103, this can include a local memory (such as, for example, a random access memory and a cache memory) employed during execution of program instructions. Regarding the processor 313, this executes computer program instructions (such as, for example, an operating system and/or software programs), which can be stored in the memory device 315.
In various embodiments the processor 313 may be implemented by any suitable processing circuit having one or more circuit units, including a digital signal processor (DSP), graphics processing unit (GPU) embedded processor, a visual processing unit or a vision processing unit (both referred to herein as “VPU”), etc., and any suitable combination thereof operating independently or in parallel, including possibly operating redundantly. Such processing circuit may be implemented by one or more integrated circuits (IC), including being implemented by a monolithic integrated circuit (MIC), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), etc. or any suitable combination thereof. Additionally or alternatively, such processing circuit may be implemented as a programmable logic controller (PLC), for example. The processor may include circuitry for storing memory, such as digital data, and may comprise the memory circuit or be in wired communication with the memory circuit, for example. A system on a chip (SOC) implementation is also common, where a plurality of the components of the camera 103, including the processor 313, may be combined together on one semiconductor chip. For example, the processor 313, the memory device 315 and the network interface of the camera 103 may be implemented within a SOC. Furthermore, when implemented in this way, a general purpose processor and one or more of a GPU or VPU, and a DSP may be implemented together within the SOC.
In various example embodiments, the memory device 315 coupled to the processor 313 is operable to store data and computer program instructions. The memory device 315 may be implemented as Read-Only Memory (ROM), Programmable Read-Only Memory (PROM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), flash memory, one or more flash drives, universal serial bus (USB) connected memory units, magnetic storage, optical storage, magneto-optical storage, etc. or any combination thereof, for example. The memory device 315 may be operable to store in memory (including store in volatile memory, non-volatile memory, dynamic memory, etc. or any combination thereof). The memory device 315 need not necessarily be a single device, but instead may be comprised of a plurality of separately packaged electronic articles of manufacture inserted into, provided inside, or otherwise provided locally at the camera 103.

First, the illustrated computer-implemented method 400 includes initially detecting (410) that a water vessel is present as a foreground object within at least one FOV of a respective at least one camera. Referring to
It will be understood that a water vessel is a vessel that is movable over a body of water, and the body of water consistent with the present example embodiment is a background object that occupies a first region of the FOV of the aforementioned at least one camera. Within

Regarding the above-mentioned third region, this corresponds to a part of the body of water that is closer to a protected structure than the second region (the protected structure may be located at or physically connected to land abutting the body of water).
Because larger water vessels have larger stopping distances (i.e. with all other factors being equal) it will be understood that the third region will be relatively larger for larger water vessels (and conversely relatively smaller for smaller water vessels). This difference is diagrammatically illustrated in
Other factors besides the water vessel size may impact relative size of the above-mentioned third region including, for example, a measured wind speed and direction, and loading of the water vessel (the loading of the water vessel may be already known, or alternatively video analytics may be provided that may be capable of generating an estimate of loading for at least certain types of water vessels).

Other examples of providing a real-time excessive velocity notification are contemplated. For instance, the real-time excessive velocity notification could be communicating over at least one radio wave signal for audible communications receipt by one or more persons present on the water vessel (for example, the small water vessel 502 or the large water vessel 608).
Other types of analytics-based alarm(s) are contemplated. For example: i) abnormality in the water vessel's direction of travel (for instance, the travel path is such that the water vessel does not appear to be moving towards a designated dock; ii) abnormality in the water vessel's containers (for instance, one or more containers could be slanted in orientation such as to evidence some risk of falling overboard); iii) abnormality in some separation distance (determining that a separation of the water vessel with respect to port infrastructure or some other water vessel is too small).
Not all example embodiments are limited to water vessels. In this regard,
As should be apparent from this detailed description, the operations and functions of the electronic computing device are sufficiently complex as to require their implementation on a computer system, and cannot be performed, as a practical matter, in the human mind. Electronic computing devices such as set forth herein are understood as requiring and providing speed and accuracy and complexity management that are not obtainable by human mental steps, in addition to the inherently digital nature of such operations (e.g., a human mind cannot interface directly with RAM or other digital storage, cannot transmit or receive electronic messages, electronically encoded video, electronically encoded audio, etcetera, and a human mind cannot define and set region boundaries for application to an FOV of a camera, among other features and functions set forth herein).
In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings. The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has”, “having,” “includes”, “including,” “contains”, “containing” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a”, “has . . . a”, “includes . . . a”, “contains . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially”, “essentially”, “approximately”, “about” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1% and in another embodiment within 0.5%. The term “one of”, without a more limiting modifier such as “only one of”, and when applied herein to two or more subsequently defined options such as “one of A and B” should be construed to mean an existence of any one of the options in the list alone (e.g., A alone or B alone) or any combination of two or more of the options in the list (e.g., A and B together).
A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
The terms “coupled”, “coupling” or “connected” as used herein can have several different meanings depending on the context in which these terms are used. For example, the terms coupled, coupling, or connected can have a mechanical or electrical connotation. For example, as used herein, the terms coupled, coupling, or connected can indicate that two elements or devices are directly connected to one another or connected to one another through an intermediate elements or devices via an electrical element, electrical signal or a mechanical element depending on the particular context.
It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors and field programmable gate arrays (FPGAs) and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and/or apparatus described herein. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used.
Moreover, an embodiment can be implemented as a computer-readable storage medium having computer readable code stored thereon for programming a computer (e.g., comprising a processor) to perform a method as described and claimed herein. Any suitable computer-usable or computer readable medium may be utilized. Examples of such computer-readable storage mediums include, but are not limited to, a hard disk, a CD-ROM, an optical storage device, a magnetic storage device, a ROM (Read Only Memory), a PROM (Programmable Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory) and a Flash memory. In the context of this document, a computer-usable or computer-readable medium may be any medium that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device.
Further, it is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein will be readily capable of generating such software instructions and programs and ICs with minimal experimentation. For example, computer program code for carrying out operations of various example embodiments may be written in an object oriented programming language such as Java, Smalltalk, C++, Python, or the like. However, the computer program code for carrying out operations of various example embodiments may also be written in conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on a computer, partly on the computer, as a stand-alone software package, partly on the computer and partly on a remote computer or server or entirely on the remote computer or server. In the latter scenario, the remote computer or server may be connected to the computer through a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).

It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure.
