摘要： Framework for processing a point cloud of an object includes an electronic device coupled to a testing device. The testing device includes a worktable and a scanning device. The worktable has a number of labeled points. The electronic device controls the worktable to rotate at predetermined angles of rotation, and controls the scanning device to scan the worktable at each angle of rotation. A number of sets of points scanned by the scanning device is obtained. A transformation matrix of the sets of points is calculated according to coordinate positions of the labeled points of each set of points. A number of point cloud sets of an object placed on the worktable is obtained by scanning the object at corresponding angles of rotation. The point cloud sets are combined to obtain an overall point cloud according to the transformation matrix, and overlapping points of the overall point cloud are removed.
