The point clouds data were assembled through LiDAR USA.
uThe Total Point Clouds Captured By Drone Camerav The next image indicates original point-clouds of a tree taken from drone camera.
The next indicates point clouds where the point dencity is increased for processing.
Four images are on different viewpoints. Each image adopts color mapping.
The increased points makes it possible for polygon generation.
The trunk and branches are polygons. Wands and leaves are points as they are.
