Algorithm 2
The region growing algorithm for point cloud segmentation.
Input: Point cloud = , point normals , residuals , neighbor finding function , residual threshold , angle threshold | Output: Leaf point cloud | (1) Initialize Region List , Available points list | (2) while is not empty do | (3) Current region , Current seeds | (4) Point with minimum residual in | (5) | (6) | (7) for to size () do | (8) Find nearest neighbors of current seed point | (9) for to size () do | (10) Current neighbor point | (11) if contains and | (12) then | (13) if | (14) then | (15) end-if | (16) end-if | (17) end-for | (18) end-for | (19) Add current region to global segment list | (20) end- while | (21) Sort according to the size of the region. | (22) Return |
