摘　　要：基于嵌入式操作系统和开发环境,利用精密三角高程测量算法,进行了精密三角高程测量的功能设计和算法实现,并通过某桥梁工程的应用对算法实现进行了数据分析和精度评测实验。结果表明,在地形起伏变化和坡度较大的区域,采用本文算法,精密三角高程测量可以达到水准测量相当的精度。通过合理设定棱镜常数、观测距离、测回数目等关键技术参数,嵌入式精密三角高程测量在地形复杂地区工程测量应用中,完全可以代替传统水准测量技术。Based on embedded operating system and development environment, using the precise triangulated height measurement algorithm, it has carried on the precise triangulated height measurement function design and algorithm imple- mentation. Through a bridge engineering application it realized the experiment of data analysis and accuracy evaluation to this algorithm. Results show that using the embedded algorithm in complex terrain region, precise triangulated height meas- urement can achieve the considerable precision of the leveling. Embed precise triangulated height measurement can replace the traditional leveling technology through setting the prism constants, observation distance and account with reasonable val- ue. In the complex terrain region engineering survey application, it has very high application potential.
