| Abstract: | Recently, structured light system (SLS)-based selective data acquisition, where the complexity of the object surface is analysed before acquiring surface data, has been introduced as an alternative to traditional reverse engineering approaches that normally acquire the point cloud from the entire object surface and perform data reduction prior to model reconstruction. Presented in this paper is an attempt to simplify and to improve the performance of the acquisition part of SLS-based selective data acquisition. Rather than being used to make recommendations to an acquisition device on where to obtain contours, the sets of projected bright line images are used to create contours directly. All contours are assembled by realigning a reference that is explicitly introduced on all images to the known positions. This contour generation has been investigated under both perfect segment projection and SLS projection. Based on the results, an SLS-based contour creation algorithm has been developed, implemented and tested with various samples. |
