Space Sampling을 이용한 직접적 삼각메쉬 곡면 생성에 관한 연구
Reverse engineering technology refers to the process that creates a CAD model of an existing part using measuring devices. Recently, non-contact scanning devices have become more accurate and the speed of data acquisition has increased drastically. However, they generate thousands of points per second and various types of point data. Therefore, it becomes important to handle the huge amount and various types of point data to generate a surface model efficiently. This paper proposes a new triangular mesh generation method with scattered raw scanned data. The proposed method takes a combined approach that reduces the amount of point data by space sampling and constructs a uniformly dense mesh structure simultaneously. In our research, a uniform 3D grid is generated for both data reduction and triangulation. The grid structure is efficiently used not only for neighbor point search that speeds up the overall mesh generation process but also for estimating surface connectivity to guarantee topological correctness. Through the method, it is possible to create a uniformly dense mesh surfaces directly from dense scanned data efficiently.
