In order to solve the problem of small deformation monitoring of tower cranes that cannot be achieved by traditional monitoring methods, the study of small deformation monitoring technology based on LiDAR data to establish a threedimensional visualization model has been carried out. Use a three-dimensional laser scanner to obtain the point cloud data of the tower crane. Based on the RANSANC algorithm and the optimized ICP algorithm, the point cloud data is processed to establish a three-dimensional visualization model, and the amount of tilt of the tower crane during the work process is compared through the comparison of the results of the two scans. Therefore, it is concluded that this method has greater advantages than traditional deformation monitoring methods. It realizes the deformation monitoring of small feature points and can calculate the deformation results faster and more accurately, which reflects the intuitiveness and real-time of 3D laser scanning. It is possible to eliminate potential safety hazards as much as possible. It will provide a favorable basis for future research on subtle deformation characteristics in buildings and other fields
