Multi-polarization parameter image fusion method and system and terrain exploration monitor

The invention belongs to the technical field of polarization image processing, and discloses a multi-polarization parameter image fusion method and system and a terrain exploration monitor. Acquiring polarization intensity images at any three different angles by using a polarization camera; demodulating the polarization intensity image to obtain an intensity image, a polarization parameter image and a linear polarization degree image; preprocessing the polarization parameter image to obtain a polarization information difference image; respectively decomposing the intensity image, the polarization information difference image and the linear polarization degree image into a base layer and a detail layer, fusing to obtain a fused base layer and a fused detail layer, and reconstructing a fused polarization image. According to the fusion task of the multi-polarization parameter image, the advantage information of different polarization parameter images can be fully fused. Compared with a polarization parameter ima
