Description

APPLICATION AREA

The present invention relates to the field of data display, and more specifically to systems and methods of using graphical user interface tools to customize the display of data on a video wall.

LEVEL OF TECHNOLOGY

Video wall is a system of video displaying devices (displays, monitors), which are physically and logically interconnected and form a single screen that allows displaying large amounts of information received from various sources in a multi-window mode.

Video walls are used for the convenience of presenting a large amount of information, for example, at exhibitions, in shopping centers, at concert venues, etc. Video walls are well suited for displaying large images with a high degree of detail. Therefore, most of the prior art solutions describe the division of the video image into parts corresponding to the number of monitors on the video wall, and the subsequent synchronous supply of video data to the screens (for an example, see US 2011/0047489 A1, US 8911291 B2). Such solutions are cheaper in execution, in comparison with the use of huge screens, because if a huge display fails, its replacement will be expensive. While a video wall consists of many standard displays and if one of them fails, it can be easily replaced with a new one.

However, installation and use of video walls in premises (for example, in situational centers, control rooms, call centers, etc.), where constant monitoring of protected objects (premises, territories) is carried out, is no less useful. Such objects are usually equipped with video surveillance systems that use a variety of surveillance cameras, the data from which are processed and written to the archive. At the same time, the call centers carry out operational analysis of large volumes of received data (graphic, cartographic, text and video data).

Video surveillance systems generally mean software and hardware or hardware that uses, among other things, computer vision methods for automated data collection based on the analysis of streaming video. The aforementioned video surveillance systems rely on image processing and pattern recognition algorithms that allow video analysis according to specified criteria without direct human intervention.

How well and clearly the information from many different sources is presented on the video wall in call centers has a huge impact on the efficiency of security systems in general. At the same time, at large objects, the video wall can contain a very large number of monitors, in addition, the mentioned monitors can be connected to different servers or devices, which undoubtedly complicates and slows down the process of setting up the display of data on the video wall.

The prior art known solution disclosed in the application US 2011/0320948 A1, G06F 3/048, publ. 12/29/2011, which discloses various options for methods of providing a user interface of a display device, the method, in one of the options, comprises: inputting a user signal to select at least one mode from a plurality of modes corresponding to a video wall system device; inputting screen setting information corresponding to the selected at least one mode of the plurality of modes; and displaying a video wall setting user interface window for configuring a plurality of video wall system settings in accordance with the inputted screen setting information.

This solution, according to the description, is aimed at displaying a general video image, divided into all screens of the video wall, and differs from the proposed solution mainly in that it, in each of its implementation, contains the stage of choosing the mode of arrangement of display devices, that is, the user of the system does not himself build the presentation of the video wall based on a real video wall, but selects from templates of possible representations. At the same time, the known solution does not disclose how the correlation of real monitors and their representations is carried out.

The closest in technical essence to the claimed solution is the solution known from the prior art, disclosed in the application US 2015/0220300 A1, G06F 3/14, publ. 08/06/2015, which describes a system for setting up a video wall in real time, which contains: a video processor that processes data from a video source for display on video display devices; video canvas containing: one or more video sources connected as inputs to the video processor; and one or more display devices connected as outputs to the video processor, wherein at least one of the one or more video sources of the video panel contains a plurality of video sources, or one or more display devices of the video panel include a plurality of display devices; and a computing device separate from and associated with the video processor, the computing device comprising a processor and memory, which in turn includes stored instructions that, when executed by the processor, cause the processor to: generate a video canvas object representing the video canvas; and transmitting the configuration data to the video processor representing the configuration of the video panel object, the video processor controlling one or more display devices to display one or more sources based on the configuration data.

In the known solution, a very cumbersome system for setting up a video wall is described, while it does not disclose exactly how the video wall is configured and the correlation of real monitors and their visual representations. In addition, according to the description, this solution only deals with the display of video data.

Our solution is designed primarily for use in call centers for monitoring, video surveillance and facility control. That is, the system a priori includes video surveillance cameras and, accordingly, this is displayed in the GUI video wall settings. At the same time, our solution is not limited to displaying only video data, that is, any data can be displayed on the video wall, for example, statistical data, a map or area plan, analysis reports, etc. And by reconstructing a visual representation of a video wall of any kind on the screen of a user's computing device, which fully corresponds to a real video wall, the proposed solution simplifies the process of setting up a video wall and significantly reduces its time.

CARRYING OUT THE INVENTION

Below will be a description of exemplary embodiments of the claimed group of inventions. However, the claimed group of inventions is not limited only to these embodiments. It will be obvious to those skilled in the art that other implementations may fall within the scope of the claimed group of inventions described in the claims.

The claimed technical solution in its various embodiments can be implemented in the form of systems and methods implemented by various computing means, as well as in the form of a computer-readable storage medium storing instructions executed by a computer processor.

FIG. 1 is a block diagram of an embodiment of a system for setting up data display on a video wall. This system includes: at least one video camera (40, ..., 4m); at least two data display devices (1, 2, 3, ..., n), logically and physically combined in a video wall (30), and each data display device is connected to at least one data processing and storage device (50, ..., 5k), also included in the system and configured to process data received from video cameras, store data and transmit data to said data display devices (1, 2, 3, ..., n), while at least one processing device and data storage (50, ..., 5k), a graphical user interface (60) is installed containing data input and output means that allow the user of the system, who sees the real video wall, to customize the data displayed on it. The video cameras (40, ..., 4m) of the system, in turn, are connected to at least one data processing and storage device (50, ..., 5k) via a local or global network (Internet).

In this context, systems are understood as any computing / computer systems built on the basis of software and hardware interconnected technical means.

The video cameras are configured to receive real-time video data and transmit it over the network to at least one data processing and storage device.

Data display devices can be displays, monitors, screens, panels, etc. At the same time, the display devices of the system are physically and logically united into a single screen - a video wall.

A computer, laptop, server, tablet, etc. can act as a data processing and storage device. In this case, for data processing, each said device contains one or a combination of: processor, microprocessor, graphic processor, computer (electronic computer), PLC (programmable logic controller), configured to execute certain commands (instructions, programs) for data processing. And for data storage, said devices include at least one of, but not limited to: hard disks (HDD), flash memory, ROM (read only memory), solid state drives (SSD), optical storage devices, etc.

A graphical user interface (GUI) installed on at least one data processing and storage device is a system of data input and output means for ensuring user interaction with a computing device, based on the presentation of all system objects and functions available to the user in the form of graphical screen components (windows, icons, menus, buttons, lists, panels, etc.). In this case, the user has random access, through input / output devices, to all visible display objects - interface blocks that are displayed on the display. The input / output device may be, but is not limited to, for example, a mouse, keyboard, touchpad, stylus, joystick, trackpad, and the like.

It should be noted that the described system may include any other devices known in this prior art, for example, such as various types of sensors, input / output devices, additional display devices, etc.

Next, an example of the operation of the above-mentioned video wall display setting system will be described in detail. All the stages of the system operation described below are also applicable to the implementation of the proposed method for setting up the display of data on a video wall, which will be discussed in more detail below.

So, let us consider in detail the principle of operation of the claimed system for setting up the display of data on the video wall. Suppose the system under consideration, as well as the corresponding software, are installed on the controlled object. For example, such an object can be both a small and a large enterprise with a huge controlled area. Depending on the area of the monitored object, the number of video cameras required for complete control is installed there (one or several, not limited to). Camcorders are used to continuously receive video data from their field of view. In the case when it is required to install more than one video camera, installers preferably position them in such a way as to completely cover the entire room / territory, while the fields of view of the video cameras may slightly overlap / overlap to obtain a complete picture. Thus, during further analysis of video images, it is easy to detect various moving or stationary objects, track the trajectory of objects, identify objects, search for objects of interest, get a good one or several images of interest from video data, and also perform many other necessary actions. All installed video cameras are connected via a network (local or global) to one or several data processing and storage devices, in this case, to a server.

At the same time, a video wall is being installed in the call center where system operators are monitoring. A video wall is a kind of frame in which data display devices are mounted, for ease of understanding - monitors. The monitors are preferably installed close to each other, thus avoiding large gaps between them. This is important for the aesthetic presentation of the data. Then the monitors are physically connected to at least one computer with the system GUI installed using cables, through which the connection to the server is carried out (using the IP address and authorization parameters). Thus, the video wall is built. In this case, monitors can be either the same size or different. For example, assume that the video wall has a 6x4 configuration, that is, 24 monitors of the same size are arranged in a rectangular manner, as shown in FIG. 1. However, in the simplest case, a video wall can only consist of two monitors, or it can have a configuration of 2 × 2, 3 × 3, 4 × 2, etc. Depending on your needs, you can build a video wall from any number of monitors of various sizes, without being limited. In this case, the video wall can be built in the shape of a rectangle, square, or have a non-standard shape, for example, a cross, a star or any other shape.

As mentioned earlier, all monitors on a video wall are physically (via cables) connected to one or more computers. As an example, consider various options for system configuration, from simple to complex.

(1) The simplest option is when there is only one data processing and storage device in the system - a server. A server is a computer on which the back-end services for data processing and GUI are installed. All video cameras of the system are connected to it via the network and all monitors (data display devices from which the video wall is configured) are physically connected. This option is possible in small businesses.

(2) The next option is when there are two data processing and storage devices in the system - a server and an operator's computer. All video cameras of the system are connected via a local network to the server, which receives in real time all video data from the cameras, processes this data, stores the archive, and also sends the required data to the specified monitors by preliminary configuration. All monitors of the video wall are physically connected to the operator's computer, on which the system administrator, using the GUI tools, configures the displayed data on the video wall. At the same time, through the GUI on the operator's computer, a connection to the server via a local or global network is established.

(3) Another embodiment is when the system contains 3 data processing and storage devices - a server to which all video cameras are connected, an operator's computer to which all video wall display devices are physically connected, and an administrator's laptop. The operator's computer and the administrator's laptop are connected via a local or global network to the server, while a GUI is installed on them for configuring the video wall. The administrator on his laptop in the GUI sees the connected operator's computer with monitors connected to it, builds a visual representation of the video wall, and also configures the display of data on the video wall.

It should be noted that the system can be configured in absolutely any way, not limited to the described options, but within the scope of the claims. That is, a system in a large enterprise can contain one server to which all video cameras are connected via the network, while video wall monitors can be physically connected to a different number of operator computers (for example, it can be 10 operator computers, each of which is connected to 2 monitors video walls). And then, in this case, the administrator on his computer sees all connected operator computers with monitors connected to them and logically configures the video wall. In addition, the system can contain several servers, each of which is connected to many video cameras.

Next, let's take a closer look at configuring a video wall and setting up the display of data on it. For this purpose, a graphical user interface (GUI) is preinstalled on each data processing and storage device, containing means for data input and output. All users of the system have access to the mentioned GUI, but their powers differ. That is, system administrators will have full rights to build a visual representation of the video wall and customize the displayed data on it, while system operators will not be able to edit anything. Operators can view the displayed data, enable or disable sound on any of the video wall monitors, adjust the playback volume, and perform predefined actions.

To logically configure and configure the video wall, the system administrator enters the GUI settings on his computer and, seeing the real video wall in front of him, builds in a similar way the visual representation of the real video wall displayed in the GUI. For this, the system administrator sequentially adds the required number of visual representations of data display devices in accordance with the number of real monitors on a real video wall. It should be noted that the GUI has such a feature, according to which the aspect ratio of each visual representation of the data display device is proportional to the resolution of the corresponding real data display device. Simply put, the length and width of the visual representation of the monitor are respectively proportional to the physical dimensions (length and width) of the actual monitor. That is, the visual representation of a square monitor will be square, the visual representation of a Full HD monitor (1920 × 1080) will be a rectangle with an aspect ratio of 16 × 9, and the visual representation of a VGA monitor (640 × 480) will be a 4 × 3 rectangle (see Fig. 2 ).

Next, the system administrator places each added visual representation of the monitor in accordance with the position of the real monitor on the video wall, thus sequentially creating a visual representation of the video wall that fully corresponds to the real video wall. It should be noted that the administrator can either add visual representations of monitors or remove them. To do this, on each added visual representation there is a button in the form of a "cross" (see Fig. 2).

At the stage of positioning the visual representations of the monitors, the system administrator will be very useful such a function of the GUI, according to which each visual representation of the data display device added to the view of the video wall is assigned a sequence number corresponding to the real display device. So, at the command of the administrator, carried out by using the GUI tools, the mentioned serial numbers are displayed both on the real data display devices (monitors) connected to the system, and on each visual representation of the data display device. Thus, the administrator sees, for example, that the monitor with serial numbers 3 is located in the first row on the right on the real video wall, and accordingly places the visual representation of the third display device at the same position as on the real video wall. Therefore, it is easy for the administrator to accurately and quickly correctly match the positions of the real and visual representations and recreate the visual representation of the real video wall in the GUI. It should be noted that the positioning of each visual representation of the display device on the video wall view is carried out using a drag-and-drop method. That is, for example, the administrator adds the first visual representation of the display device, which is automatically positioned on the video wall representation in an arbitrary way (for example, centered). Then, using a computer mouse, the user "takes" this visual representation and transfers it to the position where he needs to be in accordance with the location of the monitors on the real video wall.

In addition, the positioning of the visual representations of the monitors in the system provides several features to help the user to quickly and correctly position the visual representations. The first feature is that when each visual representation of a display device is positioned on a videowall view, it is not automatically allowed to overlap. The second feature is that when each visual representation of a data display device is positioned, their faces are automatically attracted to each other and set at a distance preset by the user of the system, thus eliminating the formation of large gaps between them. That is, for example, when the system administrator has already placed two visual representations of the monitor on the videowall view, then he adds a third view of the monitor, then takes it with the mouse and drags it, trying to dock it to the second visual representation. When the administrator releases the mouse button approximately next to the second visual representation of the monitor, then the mentioned third visual representation automatically falls into the correct place, that is, without overlapping, but not too far. The edge of the third visual representation is attracted to the edge of the second visual representation of the monitor and is automatically set to a predetermined distance. The mentioned distance is preset by the administrator, for example, R = 10 mm. Thus, each new visual representation of a data display device will ultimately always be located at a specified distance from another (adjacent) visual representation of the monitor. This approach allows the user of the system to accurately and quickly position the visual representations of the monitors, without fear of making mistakes if he himself did not get where he planned.

For clarity, FIG. 2 shows an example of visual representation of a video wall in the GUI. This videowall view consists of four visual representations of actual display devices, two monitors of the same size and two more monitors of a different size. Each visual representation of a data display device displays its serial number, as well as a cross icon that allows you to remove any of the existing visual representations from the videowall view. In this case, the abutting (adjacent) faces of all representations of data display devices are located at a given distance from each other.

After the diagram of the visual presentation of the video wall is logically formed in the GUI by analogy with the real video wall, the administrator chooses from all available data what exactly will be displayed on each monitor of both the real video wall and on its presentation in the GUI.

The data selected by the user of the system and displayed on the display devices of the video wall data can be at least one or a combination of (but not limited to): video data obtained from video surveillance cameras; area plan or map of the area (controlled area); or an information window containing data related to video data. The mentioned information data related to video data can be obtained by processing and analyzing video data received from video cameras. That is, at least one data processing and storage device analyzes the received video data based on user-specified criteria for a predetermined period of time. For example, you can perform the identification of objects (person, vehicle, etc.), track the trajectory of objects, recognize the necessary attributes of a person's clothing (for example, a uniform or personal protective equipment for a person), and much more that may be necessary for control specific territory. The data obtained after the analysis is saved as reporting documents in the form of lists (for example, lists of events), graphs or tables on the data processing and storage device on which the said analysis was performed (for example, on an operator's computer or on a server). In this case, the files with the mentioned data are displayed in the GUI block, configured to set specific data displayed on the monitors of the video wall, namely, on the panel with the list of information data. Thus, the administrator sees all possible data available for display and assigns specific data for each visual representation of the data display device. It should be noted again that said data will be displayed in a similar manner on real video wall data display devices.

And to set specific data displayed on each visual representation of the data display device, the user of the system sees in the GUI one or a combination of:

(1) a panel with a list of connected video cameras and data processing and storage devices available to provide data on the video wall,

(2) a panel with a list of layouts, and each layout contains N cells with data displayed in them, where N is a positive integer,

(3) panel with a list of informational data (reports, files, documents, etc.)

(4) a map or plan of the area, on which the icons indicate the cameras connected to the system.

The system administrator selects a name from the list on any of the presented panels with the mouse, namely, either the name of the device from the list on the panel (1) or the name of the layout on the panel (2) or the name of the file with information data on the panel (3). Or, the system administrator selects the video camera icon from a map or area plan (4). And then the administrator drag-and-drop the selected name or icon to the desired visual representation of the data display device or to the desired cell.

For example, in case (1), a user with administrator rights sees a panel where all connected devices of the system are displayed, for example, 30 video cameras, 1 server and 2 operator computers. Selecting a video camera and transferring its name with the mouse to a certain visual representation of the data display device, in this visual representation, the broadcast of the video data received from the selected video camera begins. Depending on the further settings of the system user, video data from cameras can be broadcast in real time (that is, received at the moment), or you can display archived video data. If the user wants to view any information data, then on the panel with a list of information data (3) he sees the names of all information data files available for display and chooses any name from the available ones.

In case (4), a map or a plan of the area is displayed in the GUI for selection. This is convenient when you do not know, for example, the name or serial number of a video camera, but you know from what place in the controlled area you need video data. At the same time, all cameras connected to the system are marked with icons on the map of the area, and they are located on the map in the same way as in reality. Then the administrator selects the necessary video camera on the map and transfers it to a specific visual representation of the data display device.

As for the case (2), when a panel with a list of layouts is displayed in the GUI, in this case the user selects the required layout with the mouse and transfers it to the required visual representation of the data display device. It should be noted that a layout is a set of cells in which data preset by the user (both video data and information data) are displayed. For example, but not limited to, the layout can be 3 × 3, with some informational data or a map of the area displayed in the central cell, and video from 8 selected video cameras is broadcast around this cell (in the remaining 8 cells). Layouts can contain any number of cells (N) with pre-configured data in them. If all cells of the layout display only video data from different cameras, then this layout is the layout of video cameras. When the administrator transfers the name of a layout to a visual representation of a specific monitor, that layout opens on that layout, regardless of what data and how many cells on this visual representation of the monitor were installed before. That is, the visual representation of the monitor, to which the layout with N cells is transferred, will be similarly automatically divided into N cells in which the preset data is displayed. In this case, the system user has the ability to set and change the data displayed in each cell. That is, the user simply selects other data from the available ones (on panels or on a map / terrain plan in the GUI) and transfers them in the same way as described earlier to the desired cell.

The use of layouts is very useful when you need to display a lot of data (more than the number of monitors on the video wall). For example, in FIG. 3 shows a visual representation of the video wall in the GUI. This visual representation consists of 4 monitors of the same size, arranged in a T-shape, with 3 of them divided into 9 cells each, and another visual representation of the monitor is presented in a standard form. In three visual representations divided into cells, data from video cameras can be broadcast (3 video camera layouts are obtained), and in the fourth visual representation, for example, a map of the area can be displayed, on which the video cameras from which the video is being broadcast are marked with icons.

It should be noted that the system administrator, before setting up the video wall, chooses in what form (from possible options and combinations) the data for selection will be presented. This approach allows you to quickly find the necessary data for display and adjust the video wall accordingly.

Next, an example of a specific implementation of a method for setting up data display on a video wall will be described. FIG. 4 shows a block diagram of one of the embodiments of the method for setting up the display of data on a video wall.

The specified method is performed by a computer system already described above, to which at least two data display devices are connected, logically and physically united in a video wall, and at least one video camera is connected via a network, and the computer system has a graphical user interface (GUI) containing data input and output means that allow the user, who sees a real video wall, to customize the data displayed on it. And for the aforementioned setting, the method contains the stages at which the system user through the use of GUI tools:

(100) arranges the visual representation of the video wall on the screen by adding and positioning the visual representation of each display device in accordance with the number and location of the actual display devices on the actual video wall;

(200) defines, for each visual representation of a data display device, specific data to be displayed, said data being similarly displayed on real video wall data displays.

The stages of the method have already been described in detail earlier, when describing the system. In addition, since this method can be implemented using the previously described computing system, it can be extended and refined with all the same particular variants of execution that have already been described above for the implementation of a system for customizing the display of data on a video wall.

Among other things, embodiments of the present group of inventions can be implemented using software, hardware, software logic, or a combination thereof. In this embodiment, program logic, software, or a set of instructions is stored on one or more of various conventional computer-readable storage media.

As used herein, a "computer-readable medium" can be any medium or medium that can contain, store, transmit, distribute, or transport instructions (commands) for use (execution) by a computing system, such as a computer, for example. In this case, the storage medium can be a non-volatile computer-readable storage medium.

If necessary, at least some of the various operations discussed in the description of this solution can be performed in a different order from the presented one and / or simultaneously with each other.

Although this technical solution has been described in detail for the purpose of illustrating the presently most necessary and preferred embodiments, it should be understood that this invention is not limited to the disclosed embodiments, and moreover, is intended to modify and various other combinations of features from the described embodiments. For example, it should be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment may be combined with another one or more features of any other embodiment.
