Moving target tracking system and tracking method based on random medium surface diffusion light

Abstract

The invention provides a moving target tracking system and tracking method based on random medium surface diffusion light to solve the technical problem of narrow application scope of a conventional moving target tracking system and tracking method. The tracking system comprises a laser, a beam expander, rotary ground glass, a random medium, an aperture diaphragm and a detector array, wherein the light emitted by the laser forms pseudothermal light after passing the beam expander and the rotary ground glass and irradiates on a moving target to be tracked, light carrying target information is irradiated onto the scattering surface of the random medium at an acute angle, the diffusion light, of which the stray light is filtered by the aperture diaphragm, is received and acquired by the detector array, and the tracking method is used to calculate the acquired images to obtain the actual displacement of the moving target to be tracked. Target tracking is realized through diffusion light on the surface of a random medium, and the application scope is wide. The system and the method also have the advantages of simple algorithm, high tracking precision and simple system structure, and are applicable to the fields of biomedicine and earth observation.
