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.

Key words: vehicle-borne mobile surveying system, accuracy analysis, speed, point cloud, control point
