Jibin Zhao, Weijun Liu, Renbo Xia · 2012
An algorithm of effective feature line extraction for triangle mesh model is proposed. Feature line extraction of triangle mesh model is not only the key technology of revere engineering, but also an important research project of computer vision and machine intelligence. In the paper, firstly the principal curvatures and principal directions of vertex of triangle mesh model are analyzed and feature vertex is confirmed, then the method of “seed growth” to extract feature line is proposed. Experiments and applications show that the method is not only simple and extracting feature rapid, but also extract stably and exactly feature line.
