Aiming at the problem that traditional visible light imaging systems are easily affected by environmental factors and cannot accurately describe the scene information, a gradient residual generative adversarial network for polarization image fusion is proposed in this paper. In the generator network structure, dense blocks are added to the encoder part to retain more features, the gradient residual module is constructed for fusing the feature maps to enhance the texture and detail features of the image, and the multi-scale weighted structural similarity loss function and gradient loss function are designed to improve the network performance. The experimental results show that the method in this paper obtains fused images with richer texture structure and more in line with the visual sense perception of the human eye, and at the same time has the optimal objective evaluation index.
