A Proposal of Automatic Camera Placement Method for Wide Sea Area Monitoring

Abstract

Rader is essential and widely used in order to obtain information around own ship and find other ships. And GPS and Gyro sensors indicate the location and attitude of own ship but not estimate other ones. These systems are not perfect to prevent marine accidents. One of the major causes of the marine accidents is improper lookout. The authors have proposed a stereo vision system which detected ships and other obstacles and measured their 3D locations in order to improve the navigational safety. To apply the proposed methods to watching ships in the wide sea area such as a straight or port, this paper shows a method to automatically determine the arrangement of the camera system that is set up on land to monitor all over the target sea area.
