An Adaptive Merging Method between Point Clouds in Reverse Engineering

This paper introduces an adaptive merging method between point clouds from optical scanning system. The point clouds will be wrapped in the form of triangulated mesh. One is used as feature data, and the other point cloud as target data. Then the special mesh region that needs to be updated is automatic recognized through the detection of the overlapping area between the feature data and target data, and the half edge data structure and angle criterion is used. The target triangular mesh is eventually updated to the final output by replacing the recognized region with the newly added feature data points. After that, the merging data import to CAD software environment to reconstruct. Experimental results demonstrate the efficiency of the proposed method, which is suitable to rapid customization and deformation of triangular mesh model for the product innovative design with the shorten time.
