Abstract
Method of measuring a point cloud of an object includes obtaining the point cloud of the object from a storage device of the electronic device. Based on the point cloud, a triangular mesh surface is constructed and triangles of the triangular mesh surface are determined. According to the triangles, a reference plane is determined. According to the reference plane, a three dimensional (3D) object coordinate system is established. 3D object coordinates of points in the point cloud are calculated in the 3D object coordinate system. Measurement elements of a profile of the point cloud are determined and points in the point cloud corresponding to each of the measurement elements are determined. According to the 3D object coordinates of the determined points corresponding to each of the measurement elements, each of the measurement elements are fit. A distance and an angle of two fit measurement elements are calculated.
