AB  - The precise setting of the zero point represents a critical factor in non-contact measurement of mechani-cal components, particularly in areas such as the engineering and automotive industries, where high accuracy is key to quality control. This study analyzes the impact of various alignment methods-specifically the best-fit method and the datum method (3-2-1)-on the measurement results of complex geometric shapes. Experimental measurements were conducted using a laser scanner and Polyworks 2015 software. The results indicate that the best-fit method achieves higher accuracy when measuring complex and freely oriented shapes, while the 3-2-1 method provides more consistent results for simply defined geometries. These findings confirm the importance of proper alignment method selection in op-timizing non-contact measurement processes and offer new insights for improving efficiency in industrial quality control.
