Abstract: Aiming at the problem that the current multi-beam and side-scan sonar image registration methods fail to take into account the details of image deformation, the scale differences and exist local texture distortion, a iterative adaptive registration method combining wavelet transform, affine transform and Demons registration algorithm was proposed. By using wavelet transformation to extract the low frequency information from side scan sonar image and reconstruction images, using affine transformation and Demons algorithm to reconstruct image with iterative adaptive multi-beam image registration, obtain registration transformation model. The model is used to transform the original side-scan sonar image to obtain the side-scan sonar image constrained by the geographic coordinates of the multi-beam image. The results of example verification show that this method can effectively realize the registration of multi-beam and side-scan sonar images, and obtain the fusion sonar images with accurate position and rich texture.

Key words: multi-beam sonar image, side-scan sonar image, image registration, wavelet transformation, affine transformation, Demons algorithm
