| Research Abstract |
In this research, a set of point cloud data processing algorithms for generating mesh models of large-scale environments from point clouds acquired by laser scanning was developed. In particular, the following algorithms were developed: (1) efficient registration algorithms of point clouds of large-scale environments, (2) an effective point cloud rendering algorithm to support easy visual understanding of the scanned environments, (3) a segmentation algorithm of point clouds of urban environments, (4) pole-like object recognition and classification algorithms from point clouds, and (5) mesh modeling algorithms of the objects in urban environments. The effectiveness of each algorithm was evaluated through the experiments using several point clouds, and it was confirmed that the mesh models of the pole-like objects and street trees could be generated efficiently from point clouds of urban environments using the developed algorithms.
