In the paper, there is presented the comparison of the quality of three-dimensional object measurement by scanning devices using a coherent light beam and a structured light field. Several selected issues from the fringe pattern analysis, as well as the characteristics of terrestrial laser scanning are also presented. The comparative analysis was performed to scan a crankshaft in order to assess the measurement accuracy of both scanners. By applying the appropriate software for the resulting point clouds we created a three-dimensional model of the crankshaft and made adequate comparative measures.
