Feature Hole Extraction using 3D Point Cloud Segmentation and its Application to Registration

Abstract

Especially for large scale measurement using laser trackers, registration between measured 3D point cloud and reference (CAD) data is widely required. In this study, feature hole extraction using 3D point cloud segmentation was studied. Measurement device was set as a line scanner mounted on CMM of which integrated measurement range was about 1000 mm. We introduce the trial of automatic initial alignment using extracted features.
