摘要
Radar detection is a useful technique in ship navigation and collision avoidance, especially in bad weather conditions. However, radar image cannot show the actual location of target in the electronic chart directly. In order to solve this problem and comprehensively utilize the information of both radar and electronic chart, the two images should be matched beforehand. In this paper, a multi-scaled registration algorithm fir radar image and electronic chart is presented. Based on the scale-space theory, coastlines from the two images are matched in both phase domain and image domain with continuous scale level.
