Abstract
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 large-scale unorganized 3D scanned datasets into layered datasets firstly. Then based on data parallel mechanism, a loosely coupled parallel reconstruction algorithm is designed; the algorithm has less inter-node 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.
