Abstract

Abstract: The urban intelligent perception and precision measurement engineering center, which is jointly established by Wuhan University and Beijing Urban Construction Survey and Design Institute. Based on in-depth study of the current situation of subway tunnel structure monitoring, it applies mobile 3D laser measurement technology to subway tunnel structure monitoring, proposes a set of hardware integration scheme suitable for tunnel structure and disease monitoring, and develops a set of efficient and fast underground acquisition method. The method of three-dimensional geometric characteristics of spatial structure realizes the high-precision extraction to tunnel structure apparent geometric features and disease monitoring results and obtains significant social and economic benefits. In the paper, it through the development of rail transit tunnel full section intelligent identification and analysis system and testing equipment realizes the evaluation of rail transit full section disease intelligent monitoring and tunnel service status.

Key words: 3D laser measurement, tunnel structure monitoring, platform research and development, equipment research and development, disease intelligent recognition
