Abstract: In view of the accuracy evaluation of the ground 3D laser scanner used in the deformation monitoring of urban rail transit, this paper mainly describes the three error sources of 3D laser scanner: itself, external environment and scanned targets. We analyzes the error of ranging and angle measurement of 3D laser scanner and verifies the feasibility of 3D laser scanning technology used in rail transit deformation monitoring through experiments.

Key words: 3D laser, accuracy evaluation, deformation monitoring, ranging, angle measurement
