摘　　要：为解决三维重建过程中重建数据计算量大、重建时间长等问题,提出了基于散乱点的三维重建并行策略。利用任务池的方法,实现了任务分配过程中的动态负载平衡。基于可视化工具包VTK对待重建的图像进行体绘制和可视化。通过仿真实验对并行算法的性能进行了量化分析,实验结果表明所提并行策略能够提高重建速度,缓解重建精度与重建速度之间的矛盾。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 improve the speed of reconstruction and make a balance between the speed and the precision.
