摘要
利用透视投影几何关系和摄像机内部参数,计算船舶与各陆标之间的距离,提出一种基于单目机器视觉的船舶测距定位方法。仿真结果表明,该方法与传统的陆标定位方法相比,具有简易、实时、受海况影响小的优势,可满足全封闭舰船陆标定位要求。
By using projective geometry and camera intrinsic parameters and calculating the distance between ship and landmarks, a method of locating ship by measuring the distance based on monocular camera machine vision is presented in this paper. The simulation result shows that compared with the traditional method of landmark location this method is easier, simpler and more practical, and less affected by sea situation. Also, this method can meet the locating demand of entirely closed ships.
