Abstract
In civil engineering, point cloud data are used for construction site monitoring. However, with such massive datasets, processing these data have barriers due to the size and computational intensity. This study presents the first scalable Hadoop based point cloud management and processing framework to overcome those barriers. The framework consists of 3 layers: (1) storage layer; (2) operation layer; (3) interactive layer. The storage layer is optimized by indexing techniques to accelerate the map-reduce applications. The operation layer is equipped not only with the common operations such as range query, kNN, or spatial join, but also with two powerful modules including "Change Detection"and "3D Geometric Model", for efficient monitoring. The Interactive layer enables users to approach a parallel processing model on Hadoop without requiring deep related knowledge. In addition, this layer could also visualize massive point cloud data directly from Hadoop, which is useful for analytical processes. With such components, our framework is scalable, inexpensive, and full-fledged.
