Registration of Terrestrial Laser Scanning Data Based on Projection Distribution Entropy
Fig. 1. Point cloud distributions corresponding to different rotation parameters. (a) Correct registration;(b) incorrect registration 1; (c) incorrect registration 2; (d) point cloud distribution of correct registration; (e) point cloud distribution of incorrect registration 1; (f) point cloud distribution of incorrect registration 2
Fig. 2. Relationship between entropy change and rotation angle around z axis. 0° corresponds to space distribution of correct registration
Fig. 3. Three groups of point clouds before and after registration. (a) Dataset 1 before registration; (b) dataset 2 before registration; (c) dataset 3 before registration; (d) dataset 1 after registration; (e) dataset 2 after registration; (f) dataset 3 after registration
Fig. 4. Registration errors caused by view change and structural similarity and symmetry. (a) Incorrect registration caused by view change and structural symmetry; (b) incorrect registration caused by structural similarity; (c) incorrect translation caused by structural similarity; (d) rotation error caused by structural symmetry
Fig. 5. Registration error and time in terms of different tG. (a)(b) S2-S3 of dataset 1; (c)(d) S2-S3 of dataset 2; (e)(f) S1-S2 of dataset 3
