Abstract

The invention discloses a method and system for synchronously processing light splitting and polarization spectrum information. The system includes a lower computer and an upper computer, wherein the lower computer is connected with three CMOSs ​​through light splitting to obtain three different directions of polarization in the same band and the same main optical axis. Image; the upper computer is connected to the lower computer through the USB port, and stores the polarization images in three different directions obtained by the lower computer, uses the phase correlation method to correct the displacement changes of the three polarization images, and uses the linear tuning method to calculate the polarization parameters. Four polarization parameter images, and finally based on the PCA method, the polarization parameter image and the polarization degree image are fused to obtain the polarization characteristic image, and the polarization characteristic image and the synthetic light intensity image are fused and displayed based on the dual-channel PCNN. The invention can realize effective acquisition of polarization spectrum information and improve imaging quality.

Description

technical field [0001] The invention belongs to the technical field of image acquisition and processing, and in particular relates to a method and system for synchronous processing of spectroscopic polarization spectrum information. Background technique [0002] Polarization imaging is the process of using the obtained information to reconstruct and enhance the target on the basis of obtaining the target polarization information in real time. It can provide more dimensional target information. It is a cutting-edge technology with great application value, especially suitable for stealth , camouflage, and false target detection and recognition, and can improve the target detection and recognition capabilities of photoelectric detection equipment in harsh environments such as smog and smoke. [0003] Polarization is one of the basic characteristics of light. Any object will show polarization characteristics determined by its own characteristics and the basic laws of optics in t...
