A case study was conducted on the left side of the K146 + 150 point at S236 Boshan section, Shandong Province, and research results show that from 14 August 2018 and 9 November 2019, the overall deformation of the slope was small with a maximum value of 0.183 m, and the slope will continue to maintain a stable state without special inducing factors such as earthquake, heavy rainfall and artificial excavation. In order to integrate the advantages of point measurement and surface measurement, an improved point cloud comparison method was proposed and the optimal model parameters were determined through model tests. The results show that they were superior to other algorithms (such as speeded-up robust features (SURF) feature points, Harris feature points, and Levenberg-Marquardt (LM) improved ICP algorithm) when taking the Stanford Bunny as an example, and had high applicability in coarse and fine registration. He has published over 19 journal articles indexed in Web of Science, attended 9 conferences, and won three awards. His background in surveying engineering, geomatics, and remote sensing inform his mindful but competitive approach. Internationally known editors, reviewers and columnists deliver the latest results of their research worldwide, dealing with the. He is fuelled by his passion for developing algorithms for remote sensing and geospatial applications. Coarse registration method of point cloud based on scale-invariant feature transform (SIFT) feature points and fine registration method based on the k-dimensional tree (K-D tree) improved iterative closest point (ICP) algorithm were proposed. The Journal of Laser Applications is the official journal of the Laser Institute of America and serves as the major international forum for exchanging ideas and information in disciplines that apply laser technology. Terrestrial laser scanning (TLS) is highly applicable to this field. Slope deformation monitoring is the prerequisite for disaster risk assessment and engineering control.
