Description

A useful model for the field of video shooting, namely, video cameras for receiving and processing video data in 4k format with an overview of 360x360 degrees, and can be used in security surveillance systems.

Spherical (panoramic) video cameras known from the prior art are mainly used in spacious rooms to ensure continuous and seamless recording of everything that happens on the territory. Using a wide-angle lens or several conventional lenses mounted on one device provides a circular view of the room. All collected video data is transmitted to a server, which either splits the picture into several “screens” or displays a panoramic view. The main distinguishing feature of panoramic surveillance cameras is the large viewing angle provided by one unit of the device. If a conventional video camera records within 60-100 degrees horizontally and 90 degrees vertically, then using panoramic video cameras you can achieve a horizontal and vertical view of 360 degrees. In this case, the post-processing of the video image with the selection of images and objects present on it is carried out using (external) computing devices (servers) outside the camera.

The advantages of panoramic cameras are:

- the absence of “blind” zones, since a panoramic video camera shoots a seamless picture, which allows you to capture the movement of an object from one section to another without losing sight of it, as happens between cameras, when shooting with conventional video cameras;

- Reduced installation, maintenance and consumables costs, as one panoramic video camera replaces more than 30 conventional video cameras.

The disadvantages of the prototype video camera are the need to use powerful external server equipment for processing and analyzing video data, as well as the need to use a powerful external network infrastructure for transferring video data from the video camera to the server equipment, which increases the cost of using a panoramic video prototype.

The technical result of the claimed utility model is the creation of a video camera for receiving and processing 4k video with an overview of 360x360 degrees with lower cost of use and increased functionality, due to the absence of the need for external computing systems and an external network infrastructure for processing and analysis of video images, including detection move the object in the video image, while processing and analyzing the video image using internal compute nyh funds camcorder.

Let us consider in more detail the functioning of an embodiment of the claimed video camera for receiving and processing video data in 4k format with an overview of 360x360 degrees (Fig. 1, 2).

In FIG. 2 is a structural diagram of the claimed spherical video camera with viewing angles of 360x360 with a built-in video analytics function. The video camera consists of a housing in which two lenses 1, 3 with viewing angles of 360x210 degrees and two photosensitive matrices 2, 4 with a resolution of 12 MP 4K are installed. The matrices are connected to the auxiliary switching module 10 (VMK) via the MIPI interface. In the auxiliary switching module 10, there is a navigation receiver 13, a power supply 14, a slot 15 for connecting a microSD card, USB interfaces 16, a charger 17, a rechargeable battery 18 and an Ethernet PoE 19 switch. All connectors for connecting external devices, a power button and LED indication moved to a separate panel 11 switching and display. All camera interfaces are connected to the processor 5, which is also located on the auxiliary switching module 10. The processor software implements the functions of processing video data coming from photosensitive matrices 2, 4, forming a single panoramic video image, and video analytics algorithms.

Using two light-focusing lenses 1, the light flux is focused on two photosensitive arrays 2, 4. Each photosensitive array 2, 4 generates an analog signal and transmits it to its control system 6, 7 with a built-in analog-to-digital converter, after conversion, in which the video data 5 cameras are transmitted to the processor via the synchronous interface. Control systems 6, 7 adjust the brightness, contrast and white balance for each video frame. The processor 5 generates a clock signal and transmits both photosensitive arrays 2, 4 to the control systems 6, 7 through the synchronous interface. Thus, video frames from both photosensitive arrays 2, 4 arrive at the processor 5 synchronously at uniform times. The processor 5 in real time converts the video frames from two photosensitive matrices 2, 4 into a single video frame with viewing angles in the space of 360x360 degrees, after which each converted video frame is transmitted to the analysis module 8, in which the video data is analyzed using algorithms based on the use of neural networks , for the presence of moving objects in the frame. After conversion, each frame is transferred to a data storage module 9, which records video data in a non-volatile memory device.

Although the embodiment of the utility model described above was set forth to illustrate the present utility model, it is clear to those skilled in the art that various modifications, additions and replacements are possible without departing from the scope and meaning of the present utility model disclosed in the attached utility model formula.
