Abstract During the accuracy registering for scanning point set of complex aviation casting and forging blank part
and the CAD model, the vast amounts of point set, lots of model faces and no relevance between the points and CAD model
surfaces can bring amounts of calculation for the registration algorithm, and restrict the processing efficiency severely. In
order to improve the efficiency of registration, this paper proposes a fast and high accuracy adaptive method to register
blank points and CAD model. This method uses registration surface to extract the registration points, and the correspondence
between point and surface can be built by the way, and classifies registration surfaces, and then gradually increases
quantity of points and surfaces to the precise registration which uses ICP algorithm. Finally, the efficiency and reliability of
the algorithm are verified by the instance.
