摘要: 针对高程传递路线受山体植被等阻碍遮挡的通视困难区域,本文联合测量机器人的自动跟踪能力,提出了一种微型无人机辅助的三角高程测量方法。其基本原理为,两台时钟同步的测量机器人首先以悬停于遮挡区域上空的微型无人机悬挂的360°棱镜为目标,进行动态测量,并利用同步观测值计算测站间的高差;然后对影响该方法精度的主要因素及应对策略进行了分析,并制定了相应的观测流程。实际测试对比结果表明,该方法能够获得较高的高程精度,有助于在通视困难区域快速完成高程传递。

Abstract: For some non-line-of-sight areas which are blocked by hills and vegetation on elevation transfer routes, an UAV assisted trigonometric leveling method combined with the automatic tracking capability of robotic total station is proposed. The principle is that two robotic total stations with synchronized clocks take the 360° prism carried by an UAV hovering over the obstacles as the target for dynamic observation, and the height difference between the stations is calculated using synchronized observations. The main factors affecting the accuracy of the method and the countermeasures are analyzed, and the corresponding observation procedures are formulated. The actual test results show that the proposed method can obtain comparable height accuracy and is helpful for rapid height transmission in non-line-of-sight areas.
