    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.
