Abstract: By synthesizing the advantages of various surveying systems at home and abroad, a visual automatic surveying system is developed in this paper. This surveying system has the important function of automatic shield tunneling guiding survey visualization and engineering dynamic management visualization, and it also has merits of simply operation and higher automation level. It has been applied to the construction of a section of railways, the result indicated that the surveying system is convenient, accurate and feasible, and can automatically accomplish the whole measurement task?? taking the place of manual measurement. Meanwhile, this system also provides the visual information of the correlations of the TPM site and the building around, which is propitious to prevent accidents caused by surroundings during the tunnel construction.
Key words : automatic-guiding survey, Shield-Driven, automatic total station, visualization
