Multiple-sensor integration for efficient reverse engineering of geometry

摘要: This paper describes a multi-sensor measuring system for reverse engineering applications. A sphere-plate artefact is developed data unification of the hybrid system. With coordinate acquired using optical system, intelligent feature recognition and segmentation algorithms can be applied to extract global surface information object. The machine (CMM) used re-measure geometric features with small amount sampling points obtained subsequently compensate point patches which are measured by Then optimized exploited accurate CAD model. limitations each measurement compensated other. Experimental results validate accuracy effectiveness this optimization approach.
