“In addition to conventional applications such as reverse engineering and product inspection, surface fitting techniques have been applied to metal part repair processes and work piece localization processes. In these new applications, the orientation and position information of the work piece are extracted from point clouds. In order to improve the accuracy of the fitted orientation parameters, sampling boundary effects, which are an innovative approach, are studied in this paper. A boundary sampling strategy is proposed and compared to grid sampling strategy, Hammersley Sequence sampling strategy, and random sampling strategy. The results showed that the boundary sampling strategy is accurate at estimating the orientation parameters in the surface fitting processes in which the linear least squares method is employed. It also provides a short digitizing path, thus, reduce motion of CMM and shorten the operation time. This method can be easily adopted in industry--Abstract, page iv.
