摘要：
Terrestrial 3D laser scanning is one of principal methods to get the geometric information of object surface, and the integrity of the scanned object is a basic requirement in data acquisition. In order to solve the missing point cloud problem due to the scanning dead angle caused by confined working space, this paper proposes a method using ordinary plane mirror to obtain laser scanning data for non-direct viewing area according to the plane mirror reflection principle, analyzes the influence mechanism of the ordinary plane mirror on the propagation path and distance of laser beam, deduces the coordinate equation of the object point corresponding to the image point reflected by ordinary plane mirror in laser scanning. Given the laser scanning characteristic, this paper introduces a mirror reflection system included target balls and ordinary plane mirror, and expounds the system construction, system calibration and constructing method of system coordinate system. The feasibility and precision of the method are verified by experiments. © 2017, Surveying and Mapping Press. All right reserved.
