Multi-polarization-degree image collecting system

Abstract

The invention discloses a multi-polarization-degree image collecting system which comprises a controller, a plurality of polarization image sensors which are connected with the controller and carry out trigger control through the controller, and a power module which supplies power to the entire system. An input end of each polarization image sensor is connected with a polarization camera which is used for collecting images, and an output end of each polarization image sensor is connected with an analog video decoder which is used for enabling the collected images to be decoded to readable information. The polarization image sensors are connected with the analog video decoder through a video input interface. The analog video decoder is connected with a microprocessor which is used for analyzing and processing decoded information of the analog video decoder. The multi-polarization-degree image collecting system is simple in structure and stable in operation, the entire device is small and exquisite in structure and light in weight, the fact that polarization images with different polarization degrees in the same scene and in the same time are collected and processed, and the multi-polarization-degree image collecting system can be used in the fields of unmanned plane detecting and the like.

Description

technical field [0001] The invention belongs to the technical field of image acquisition, and in particular relates to an image acquisition system with multiple polarization degrees. Background technique [0002] The polarization characteristics of ground targets and background light are different. Studies have shown that polarization information is not only unique in analyzing atmospheric background parameters, but also unique in identifying ground targets. When the polarization image sensor is used to detect the ground, multi-dimensional information can be obtained, and the directionality of the polarization information is helpful for the inversion of the surface state, structural characteristics and material type of the target. The detection task can be completed more effectively. [0003] The current video acquisition and processing boards on the market have many deficiencies in the acquisition and processing of polarization images. Most of the acquisition and processi...

AI Technical Summary

Problems solved by technology

Most of the acquisition and processing boards on the market are single-channel (or dual-channel) systems, which can only acquire one or (two) images, and cannot simultaneously acquire and process more than three polarization images

In some fields such as precise monitoring and precise tracking, it cannot satisfy the acquisition of image polarization information of multiple polarization degrees (more than three) in the same scene at the same time
