According to the habit and consensus of people looking around in the three-dimensional space around the scene with the front, back, left, and right directions, such as Figure 4 As shown in the view of 1, establish an azimuth compass, on this basis, design a four-azimuth compass including four azimuths evenly distributed (such as Figure 4 2 view of ), six-direction six-direction compass (such as Figure 4 3), the four-direction compass includes front, right, rear, and left, and the six-direction compass includes left front, right front, right, right rear, left rear, and left , each azimuth has attributes including azimuth name, horizontal angle of view, and vertical angle of view, and adjacent azimuths have a fixed azimuth topological relationship. The multi-channel video computer system topology diagram of a network camera group that looks around a multi-directional scene video image in a geographical three-dimensional space is as follows Figure 5 As shown in the view of 1, there are two symmetrical network camera groups in a plane Cartesian coordinate system, such as Figure 22 As shown in the view of 1, four network camera groups are arranged evenly, such as Figure 5 As shown in the 2 view of , the group of six network cameras arranged evenly Figure 5 As shown in Figure 3, the types of multiple network camera groups include two network camera groups, four network camera groups, six network camera groups, and eight network camera groups. Each network camera in the network camera group has a Its own device ID, video network address, and horizontal viewing angle (40 to 110 degrees) attribute, each network camera of the network camera group is 0 to 300 cm away from the origin of the plane Cartesian coordinate system, and is actually installed in a horizontally placed The distance difference between each network camera on the carrying device and the origin of the plane Cartesian coordinate system can be between 0 and 200 centimeters, and the difference between the longitudinal distances between the network cameras relative to the plane of the plane Cartesian coordinate system It can be between 0 and 50 centimeters, at the geometric center point of a horizontal section of a horizontally placed carrying device, with one direction as the reference, superimposing the six-direction compass, according to the rectangular coordinates of the plane where the six network camera groups are located The system is superimposed with the six-direction compass, and the six network camera groups are installed to form a six-eye compound eye network camera, such as Figure 7 As shown, the four-eye compound-eye network camera is a special case of the six-eye compound-eye network camera, such as Figure 6 As shown, the left and right binocular network cameras are a special case of the four-eye compound eye network camera, as Figure 22 As shown in Figure 2, the types of multi-eye compound eye network cameras include left and right binocular network cameras, four-eye compound eye network cameras, and six-eye compound eye network cameras. The types of multi-eye compound eyes include left and right binocular, four-eye compound eyes, and six-eye compound eyes. Just like two-wheeled carts, four-wheeled cars, and six-wheeled trucks are different from a fleet composed of N unicycles, the traditional video surveillance system composed of N network cameras with left and right binocular, four-eye compound eyes, and six-eye compound eyes areas focuses on the problem.
