Abstract
Radar is essential to safety navigation for ships. However, it is not perfect equipment and there exist marine accidents. The authors propose using stereo vision that automatically detects ships and/or other objects and measures their 3D locations in order to assist usual navigation equipment. This paper focuses on a novel method to detect ships from stereo images. The proposed method is composed of detection of edges from images, confirmation of corresponding points between left and right images, and final judgment of ships from 3D measurement results. An experiment, which used twelve pairs of stereo images obtained at Akashi Strait, was conducted. The result indicates good possibility of the proposed method, although there is room for improvement in order to ensure the detection.
