Terrestrial laser scanning (TLS) technology has the advantages of wide range, high efficiency, and low cost in spatial information collection, so it is widely used infrastructure monitoring measurement. During TLS application, registration positioning point cloud have a direct impact on quality data validity results. The linear distribution tunnel structure lack significant features present challenges 3D clouds railway tunnels. commonly methods are difficult to achieve accuracy prone...
Abstract. Recent years have witnessed a growing investigation of terrestrial laser scanning (TLS) for monitoring the deformation tunnels. TLS provides ability to obtain more accurate and complete description tunnel surfaces, allowing determination mechanism magnitude deformation, because entire surface is concretely modelled rather than being represented by number points. This paper models analyses point clouds from detect possible newly built tunnel. In application Badaling Tunnel Winter...
Abstract. This paper focuses on the analysis of point clouds from terrestrial laser scanning to interpret possible deformations new Badaling Tunnel that was built for Winter Olympics 2022 in nearby Beijing, China. A reference framework is established compare data corresponding various days with blocks uniform columns and rows an estimated tunnel axis. Filling holes detecting outliers are performed quasi-planar estimation, refinement transformation used adjust errors between different days....
