Surface Reconstruction Technology from Dense Scattered Points Based on Grid
In order to improve the speed of surface reconstruction from densely scattered points, and reduce the application cost, this paper describes a new and fast surface reconstruction method based on grid computing. The proposed method converts largescale unorganized 3D scanned datasets into layered data-sets firstly. Then based on data parallel mechanism, a loosely coupled parallel reconstruction algorithm is designed; the algorithm has less internode communication, so that it is more suitable for grid computing. In order to realize load balance in grid, the priority preemptive scheduling strategy is designed based on two-level scheduling model. Finally, the grid environment is built by Globus Toolkit, and the parallel reconstruction and visualization are achieved based on mpich-G2 and the Visualization Toolkit (VTK), this experiment shows that the reconstruction time is reduced significantly.
