Abstract
In order to enhance the image of laser imaging radar and improve the image matching effect of laser im-aging radar,a laser imaging radar image matching system based on visual communication technology is designed.Ob-tain the laser imaging radar image.After the image enhancement processing is completed by the optimized Retinex en-hancement algorithm in the visual communication technology,SIFT and rotation invariant LBP methods are used to ob-tain the rotation invariant LBP features of the key points and the area around the key points,and the laser imaging ra-dar image matching is realized according to the similarity judgment of the key points.Experimental results show that the proposed system has a maximum signal-to-noise ratio of 47 dB and a maximum structural similarity of 0.92.The high-est matching accuracy of image feature points is 97％,and the fastest matching speed is 3.6 s.The system enhances the image quality of laser imaging radar,and can realize the image matching of laser imaging radar with high precision,which provides a reliable basis and reference for practical work.
