Abstract

At present, the continuous advancement of science and technology, the requirements for digitization in various fields are getting higher and higher. As a tool for 3D point cloud acquisition, 3D laser scanners are increasingly researched and developed, and scanners with different performances are used in different fields. The registration of point cloud data by these workers is the key to the success of the project. The point cloud data of all the different coordinate systems are all registered, so that the complete point cloud data of the measured entity can be obtained, and the entity with the measured entity is Complete point cloud data is ready for the next step. This paper studies the registration method of point cloud data, discusses the commonly used registration methods in detail and then analyzes the point cloud error, and then derives the propagation model of point cloud error. Finally, design a set of schemes to complete the building. Scanning data is obtained by scanning, and the data is registered by target and non-target respectively; the differences in the registration process are compared, and the results are analyzed and compared.
