There is a problem of laser scattering in the image acquisition process of laser images, which affects the image effect. Therefore, a method for repairing laser images with backscattered light under visual communication technology is proposed. The collector collects the laser image, denoises the laser image through the sparse denoising method, applies the adaptive color correction factor in the gradient domain Tone mapping method to correct the color of the laser image, introduces the linear color correction model to eliminate the color difference of the image, and completes the back scattered light repair of the laser image based on the improved Generative adversarial network. The experimental results show that the repaired laser image using the proposed method is consistent with the actual situation of the experimental object. The similarity of the feature structure between the repaired image and the original laser image is more than 90%, and the repair time is less than 89.5 ms, indicating good repair results.
