摘要
针对传统电子经纬仪需要人眼瞄准读数,测量效率低下且测量精度易受瞄准误差影响的问题,本文提出一种新型的自动激光经纬仪系统,无需人眼瞄准即可实现经纬仪系统自动瞄准测量。该方法采用精密二维转台和高分辨率相机代替人眼,利用TM5100A的马达驱动功能将经纬仪的望远镜指向相机视场范围,实现引导跟踪功能。然后,再进一步识别并瞄准视场内的目标,完成对目标的识别和测量过程。本文主要就该系统中的跟踪引导算法进行了研究和分析。仿真和实验结果表明,该引导方法效率高,实用性强,能够较好地实现相机对经纬仪激光点的准确引导,保证了经纬仪测量系统的引导精度。
To solve the low precision and efficiency problem of traditional theodolite system due to manual target alignment, a new automatic laser theodolite system was presented which could realize automatic measurement by using a guidance system consisting of a digital camera mounted on servo stages rotating in horizontal and vertical directions. The TM5100A motorized theodolites were used to point at the view field of the camera to realize the guidance process, and then the recognition and measurement process was completed by using the recognition and measurement method. The former method was emphatically introduced and analyzed. The simulation and test result shows that the guidance methodology is feasible and efficient to realize accurate guidance of the theodolites.
