| 摘 要： | 市政管线建设中，相应的地形图对其规划、设计等起着至关重要的作用。传统方式在市政管线地形图测量中有一定的局限性，特别是大城市的重要交通要道、快速路等。而车载移动测量系统则有其得天独厚的优势，快速、高效、安全。在测图过程中，车载移动测量系统精度受各方面的影响，如车速、地面遮挡、控制点布设等。本文对车速、控制点布设线路等方面进行了试验验证，结果表明，通过一定的质量控制措施，车载移动测量系统能够很好地应用于市政管线地形图测量中。

| Abstract: | In the construction of municipal pipelines,topographic map plays a vital role in its planning and design.However,the traditional method has some limitations in topographic mapping of municipal pipeline,especially on important traffic arteries and fast road of cities.Vehicle mobile surveying system has unique advantages due to its fast,efficient and secure properties.The accuracy of the vehicle mobile surveying system is affected by various factors such as speed,ground occlusion,control point arrangement and so on.Experiments in this paper verified the vehicle speed,control points and other aspects.The results showed that the vehicle mobile surveying system can be applied to the topographic mapping about municipal pipeline through a certain quality control measurement. |
