Unmanned aerial vehicle wreckage searching system and method based on polarization imaging and infrared distance measuring

Abstract

The invention discloses an unmanned aerial vehicle wreckage searching system based on polarization imaging and infrared distance measuring. The unmanned aerial vehicle wreckage searching system comprises an imaging subsystem and a distance measuring subsystem; the imaging subsystem comprises a laser beam expanding unit and a polarization imaging unit; the laser beam expanding unit comprises a laser source and a beam expander; the polarization imaging unit comprises a polarizing film, a motor, a CCD camera and an upper computer; and the distance measuring subsystem comprises an infrared emission unit, an infrared receiving unit, an amplification unit and an upper computer. The invention further discloses an unmanned aerial vehicle wreckage searching method based on polarization imaging andinfrared distance measuring. When unmanned aerial vehicle wreckage is searched in a complex environment, the clearer imaging effect can be achieved, a target is identified better, meanwhile the distance between a target object and a measuring point is measured, and the searching range is convenient to lock.

Description

technical field [0001] The invention relates to the field of UAV wreckage search, in particular to a UAV wreckage search system and method based on polarization imaging and infrared ranging. Background technique [0002] In complex environments, UAV detection is used more and more frequently, and in unknown environments, UAVs often encounter unpredictable problems or failures, resulting in crashes and its wreckage is difficult to find. In the past, after a drone accident, a large number of personnel were dispatched to search for it, which was time-consuming and laborious. In complex terrains and environments, it is difficult for human eyes to effectively identify targets, and it is even more difficult to search at night when there is a lack of natural light. Contents of the invention [0003] The object of the present invention is to provide a UAV wreckage search system and method based on polarization imaging and infrared ranging, so as to solve the deficiencies in the p...
