By analyzing the map of multi-beam water depth false-gray image and side-scan sonar image, and adopting CANNY operator to extract contour line. Then select the turning points which cater the constraints as the feature points, and deal the feature points with quadratic polynomial algorithm to obtain the deformation model to realize image registration between the two. Finally, process the fusion result by wavelet decomposition and evaluate it by cross entropy algorithm. Data simulation shows that the result is reasonable and the method proposed in this paper is practicable. << 收起
