| Abstract: | It presents a software system of data processing for continuous deformation monitoring of the subway tunnel with the shape measurement characterized with 3D terrestrial laser scanning technology, combined with multi-temporal point clouds data high-precision, high spatial resolution. The system＇s main functions include： point clouds registration, tunnel＇s central axis fitting, continuous vertical section abstraction, deformation analysis, and results output, which are combined with the multi-period laser scanning data processing of a subway tunnel in Shanghai. The application prospect of this system is discussed finally. |
