| Abstract: | The interactive modeling system for point cloud process is designed and implemented in this paper.Based on mobile laser scanning data for buildings,RANSAC is used to detect the geometry feature from the point cloud automatically,and interactive method is applied to complete the feature detection.Boundary feature is calculated based on random algorithm and the building model is generated from adjacency graph for the polygons.Most of the operations are real-time except the feature detection,so the modeling system presented in this paper is more of effectiveness and accuracy compared with the conventional ones. |
