Abstract：A new method to assess the angle accuracy of 3D Laser Scanner is presented. TM5100 electronic theodolite was used to set up datum angle,and the angle accuracy of RIEGL LMS-Z390i Laser Scanner was assessed. The observed angle was obtained by 3D coordinate of point-clouds,and the analysed axes errors of 3D Laser Scanner is used to set up the calibration model. According to the least squares adjustment,the angle accuracy were 0.002 7° and 0.001 5°,so the new method was feasible.
