Contour extraction of point cloud data for tree branches

Abstract: 3D laser scanning technology was used with point cloud data of tree branches to measure the inherent complex characteristics and contour model of the branches was established. Branches were divided into different parts,and a hierarchical model of the tree was established. Also,distribution of the point cloud for tree height was analyzed. With high-precision sampling,the stratified point cloud was used for contour sampling data, and all points of different parts of the branches for each floor of data were connected using a convex hull algorithm. Then a contour model of the branches was established followed by validation of the model. Branches diameter of different height were extracted from the model,the error was less than 5% compared with the actual measurement value. Results showed that in the absence of prior knowledge of the contours and with the establishment of the point cloud objective model, an iterative convex hull algorithm effectively connected discrete point cloud data on the tree branches, and the model was validated. Thus,with the new contours being consistent with the original contours, feasibility of this approach was verified. [Ch,8 fig. 1 tab. 11 ref. ]
