Abstract: For the problem that the existing target tracking methods can not quickly track the high-speed moving targets, a dynamic target tracking method based on optical imaging with rotating mirror is proposed to accurately obtain the dynamic target parameters in military range experiments. A combination of high-speed camera and mirror is used to collect the multi-image information of dynamic target based on the principle of light reflection. A mathematical model of motion state of target is established. According to the angle offset of mirror, the matching relationship between the rotation parameters of mirror and the motion parameters of target is studied. The hardware platform of the system was built with embedded controller, single chip microcomputer and optical camera, and the multi-parameter control and optimization of target tracking system were realized by using the mathematical model of target motion state and the image processing algorithm. The test results show that the proposed target tracking model can be used to obtain clear target image and achieve the purpose of tracking under the variable motion state.
