目前，随着船舶的巨型化，进坞方法已成严重问题。为此，国外研制了一种跟踪激光测距系统，该系统由两部分组成：上部分装在船坞上，另一部分装在船头上用以测量船R与陆地距离、船只偏离船坞中心线的距离，以及船只中心线偏离船坞中心线的角度。该系统基本作用是测距、测位及数 At present, with the hugeness of the ship, the docking method has become a serious problem. To this end, a tracking laser ranging system has been developed abroad. The system consists of two parts: the upper part is mounted on the dock and the other part is mounted on the bow to measure the distance between the ship R and the land, and the ship deviates from the center line of the dock Distance, and the center line of the ship off the center line of the dock. The basic role of the system is ranging, positioning and number
