摘要
分析LiDAR数据处理流程,结合开放网格服务体系结构(OGSA),提出一种LiDAR数据处理平台体系,将数据处理任务合理划分并分配到各个分布的网格节点上,通过各节点并行、协同计算,达到提高运算速度的目的。最后以对激光点云重采样生成格网DEM为例,说明算法在该体系下的计算过程。
The software architecture in Light Detection And Ranging (LiDAR) data processing was described. It partitioned LiDAR data and processed task into distributed Grid nodes. Processing speed was improved by parallel computing of every Grid node. The Open Grid Service Architecture (OGSA) also provided flexible share style for LiDAR data and processing service.
