ABSTRACT
ABSTRACT: Multibeam echosounder system and Side scan Sonar can best compensate each other. In order to fully utilize all information, it needs to fuse two kinds of image and data. And image coregistration is important and complicated work before fusion. This paper presents that combine bathymetry data with intensity image, and obtains the feature points through the minimal angles of lines, then decides the corresponding image points by the maximal correlate coefficient in searching space. Finally, the second order polynomial is used to the deformation model. After image has been coregistered, Wavelet is used to fuse the images. It is shown that this algorithm can be used in the flat seafloor or the isotropic seabed. Some examples have been given following by real data.
