Abstract

The invention discloses a system and a method capable of eliminating lateral reflected light of a video image from the smooth object surface. The system comprises a camera and a polarizing filter, wherein the camera is used for acquiring the video image, and the polarizing filter is arranged in front of a camera lens and used for eliminating the reflected light generated by the smooth object surface in the video image. The polarizing filter comprises an electric field supply unit and a polarizing unit, wherein the electric field supply unit is used for supplying electric fields required by the polarizing unit, and the polarizing unit is used for converting elliptically polarized light to linearly polarized light. The system and the method capable of eliminating the lateral reflected light of the video image from the smooth object surface are capable of eliminating the reflected light generated by the smooth object surface in the video image by the aid of the polarizing filter arranged in front of the camera lens.

Description

technical field [0001] The invention belongs to the technical field of video processing, and relates to a video processing system, in particular to a system for eliminating lateral reflection of a video image from a smooth object surface; at the same time, the invention also relates to a method for eliminating the lateral reflection of a video image from a smooth object surface . Background technique [0002] The existing video surveillance system is prone to glare and glare on the surface of smooth objects, which has a great impact on the entire system. The intelligent video analysis system needs to detect abnormal targets based on the existing scene, and the interference caused by strong light is very large, making intelligent video analysis more difficult and inaccurate, and the reflected light on the water surface will seriously interfere with the target image. [0003] In view of this, there is an urgent need to design a new video surveillance system in order to elimin...
