Model construction based on CMM and optical scanning data for reverse engineering

Abstract

This paper introduces a combined modeling method using points acquired by a touch probe on a coordinate measuring machine and an optical scanner. The optical scanning data and the high precision points captured by a touch probe are transformed into a common coordinate system through an improved iterative closet point algorithm. A data merging method is used to keep the high precision of feature surfaces and then unified into a precise 3D model. Experimental results demonstrate the efficiency of the presented method, which enhances the flexibility of digitization while maintaining the accuracy of feature surfaces. © Springer-Verlag Berlin Heidelberg 2011.
