The parameters that can be set in the process of system calibration are discussed in the paper, and the scanning results with parameter change are evaluated based on the indicators of camera and projector’s reprojection error, scanning resolution and point cloud’s uniformity. The research concludes that the distance between the projector and the calibration board is a key factor needs to be controlled. It can be set up properly based on the indicators for the quality of scanned data, which improves the speed of system calibration and keep the collected point cloud data more stable. |
