A comparative analysis of measurement results obtained in measuring parts having complex geometric shapes by means of 3D scanners and CMM
Abstract
This study compares the dimension measurements results obtained for two parts that had convex and concave parabolic profiles. Three different measurement systems were employed for measurements: coordinate measuring machine (CMM), 3D laser and 3D photometric scanners. It was found using Student’s t – test that results obtained by CMM measuring system are statistically significantly (p < 0.001) more accurate than results obtained by means of 3D laser and 3D photometric scanners. It was also established that results obtained by means of 3D laser scanning system are statistically significantly more accurate (p < 0.05) than those obtained by means of 3D photometric scanning system.
