Abstract

Building installation quality inspection is an active research field in the overlapping fields of engineering survey and civil engineering. Furthermore, ensuring the installation quality of temporary buildings in large-scale sports events has more practical and social significance. In this paper, Terrestrial Laser Scanner (TLS) is used to acquire the point cloud of the steel portal frame of the Zhangjiakou Olympic restaurant. Based on the established building coordinate datum, the data of the whole model is simplified, components are extracted and classified. This paper presents an automatic measurement method of verticality and deflection based on point cloud model. The results demonstrate that the mean error of verticality of the steel portal frame is ±0.002 m, and the mean error of member deflection is better than ±0.028 m. The whole structure installation quality meets the specification requirements. The terrestrial laser scanning (TLS) measurement meets temporary building installation detection accuracy requirements.
