摘　　要：精密三角高程测量利用两台高精度测量机器人对向观测,大大削弱大气折光的影响,并且无须量取仪器高和棱镜高,避免了该项测量带来的误差,能够达到国家二等水准测量精度的要求。对精密三角高程测量方法进行研究,利用C++编程语言开发了精密三角高程测量系统TriLevel,该系统基于地理数据通信接口(GEOCOM)与测量机器人进行通讯,实现精密三角高程自动化测量和质量控制。通过在青海地区开展实际工程应用,与二等水准测量结果进行对比,结果表明:该系统能够达到二等水准测量精度要求,且工作效率有很大的提高。应用成果对类似高程传递测量具有一定的借鉴意义。Precision trigonometric leveling uses two high-precision measuring robots to observe in the opposite direction,which greatly weakens the influence of atmospheric refraction,and does not need to measure the instrument height and prism height,which avoids the error caused by the measurement,and can meet the national second-class leveling accuracy requirements.In this paper,through the research of precision trigonometric leveling method,the Precise Trigonometric Leveling System trilevel was developed with C++.The system communicates with the surveying robot based on GeoCOM to realize the automatic measurement and quality control of Precise Trigonometric Leveling.Through the practical engineering application in Qinghai area,the results showed that the system could meet the accuracy requirements of second-class leveling,and the working efficiency had been greatly improved.The method provides reference for the similar height transfer survey.
