| Abstract: | To resolve some problems in the process of three-dimensional (3D) reconstruction, which include huge computing data and long time for reconstruction, a parallel strategy of 3D reconstruction based on scattered points was put forward. Dynamic load-balance in the process of task assignment using task pools was carried out. And volume rendering and visualization based on Visualization Toolkit (VTK) were implemented. The advantage of parallel strategy is validated through simulation experimentation. It can impr... |
