In order to enhance the blurred laser image, the enhancement method of blurred laser image based on visual communication technology is studied. The physical model including attenuation model and ambient light model is constructed, the influence of atmospheric environment and other factors on the initial laser image is described, the ambient light and global atmospheric light coefficients in blurred laser image are determined, and the image deblurring process is carried out in combination with the constructed physical model. The Retinex adaptive enhancement algorithm is used to enhance the laser image from three aspects: saturation adaptive stretching, brightness enhancement and color restoration. Experimental results show that the proposed method can achieve better deblurring effect, and has certain advantages in brightness, contrast and color fidelity, which can improve the visual communication effect of blurred laser images.
