基于集群技术的实景三维建模研究

随着无人机技术在续航能力和相机分辨率方面的不断提升，目前不断发展起来的集群技术为单一工作站在大测区实景三维建模方面提供了有力支撑。详细论述了集群技术的具体组成、并行计算方式、集群技术下在ContextCapture软件中实景三维模型实现的过程。最后，将量测实景模型上检查点的三维坐标与实测坐标值进行对比，得到检查点的平面位置和高程中误差，验证了集群技术在实景三维模型中应用的可行性。

Research on Real Scene 3D Modeling Based on Cluster Technology

With the improvement of UAV technology in cruising ability and camera resolution, the cluster technology that has been continuously developed provides a strong support for a single workstation in 3D modeling of a real scene in the large survey area. The specific composition of cluster technology, the parallel computing method and the process of realization of the real 3D model in ContextCapture software under cluster technology are discussed in detail. Finally, the three-dimensional coordinates of the checkpoints on the real scene model were measured and compared with the measured coordinate values to obtain the plane position and elevation errors of the checkpoints, which verified the feasibility of the application of cluster technology in the real scene three-dimensional model.
