摘要：This study deals with the development of methods for the evaluation of the resolution of terrestrial laser scanners. For this purpose, experiments were accomplished using the laser scanner Cyrax HDS 3000, that was produced by Leica-Geosystems. Two methods for the evaluation of the resolution and the beam are compared: the direct method, based on the analysis of the capacity of the laser beam to penetrate in the spaces of a grid, and an analytical method, that models the resolution of the beam based on the border effect. The proposed methods are efficient for evaluation of the resolution of laser scanner systems and they can be used to improve the quality of the surveys using terrestrial laser scanners.
