Problems solved by technology

The software verification platform can only verify the algorithm's detection and tracking of the target in the known image sequence, but cannot verify the algorithm's control of the pan / tilt, resulting in the verification platform not being able to close the loop, and the background environment of the target is quite different from the real scene of the airborne target indication system. Large; in the semi-physical simulation verification platform, the application number is: 201310231739.9, and the Chinese patent titled "UAV digital photogrammetry simulation teaching system" uses a single visible light camera as the target detector, the application number is: 200910066445.9, and the name is " The Chinese patent of a simulation system for the terminal guidance section simulates the distance change between the camera and the target by changing the focal length of the camera. System" Chinese patent and application number: 201410127206.0, the Chinese patent named "a soft landing obstacle avoidance simulation test system" uses a multi-rail way to simulate the distance change between the camera and the target, and the airborne target indication system The target background faced by the field is a complex environmental background. The target will face the interference of factors such as changes in the brightness of the surrounding environment, changes in the climate, and partial occlusion by objects. Only using visible light detection methods cannot achieve reliable detection and tracking of the target. , the use of complex multi-rail way to achieve the relative movement between the detection device and the target, the mechanical structure and motor control are very complex, will reduce the reliability of the simulation system, and will greatly increase the cost of the simulation system
