Method and apparatus for determining an unsupervised planar geodesic path |
摘要 |
The present invention provides a system and method for performing three-dimensional surface measurements of a path length along a surface. The method for determining the path length along the surface of a three-dimensional object includes the step of first selecting a first and second point on the three-dimensional surface. A plane is then defined which contains both the first and second points. A determination is then made to find the shortest path curve between the first point and second point which is defined by the intersection of the three-dimensional object with the plane. This path length is recorded for future comparison. A series of subsequent planes is defined that contains the first and second point, wherein these planes are rotated at an angle to each other. A determination is then made for the shortest path length associated with each subsequent plane. The overall shortest path length is the minimum of these recorded path lengths.
