An effective way to eliminate the accumulative error of multi-view registration

Error analysis of free-form surfaces is a requirement to assure quality and to reduce manufacturing costs and rework. This paper proposes a new approach and algorithms for eliminate the accumulative error of multi-view registration. The main influence factor of sequential sub-surface registration error is analyzed detailedly. To eliminate accumulated errors of registration, a method based on an overall errors compensation method is proposed, which distributes accumulated errors to each of transformations, depending on a concept that continued registration errors of surfaces in closed form is zero. And, overlapping area can be chose reasonably. Experimental results showed that the proposed method is effective.
