多源数据融合在大型市政工程竣工测绘中的应用

The Application of Multi-Source Data Fusion in Surveying and Mapping of Large-Scale Municipal Projects Completion Stage

针对大型市政工程竣工测绘中普遍存在的工期紧、任务重的问题,介绍了基于多源测量、数据融合的“空地一体化”的作业模式。通过在成都市东西城市轴线东段竣工测绘的应用,梳理了各测量方式的作业流程,分析了其优缺点,总结了相关经验,并通过对1∶500地形图成果的精度分析验证了此模式的可行性。

Aiming at the problems of tight time limit and heavy task in the completed stage surveying and mapping of large-scale municipal projects,this paper introduces the operation mode of“space-ground union”based on multi-source measurement and data fusion.Through the application of completed stage surveying and mapping in the eastern section of the east-west axis in Chengdu,the operation process of each surveying method is sorted out,its advantages and disadvantages are analyzed,the relevant experience is summarized,and the feasibility of this model is verified by the accuracy analysis of 1∶500 topographic map results.
