摘要
This invention is about the method for detecting the position, and orientation of holes using a robotic vision system. In certain industrial applications, there are parts with many tiny or large holes or tunnels of various shapes, and the orientation and position of each of the holes need to be inspected automatically using non-contact measuring systems such as a vision system. The relative motion of the hole being measured and the measuring system can be realized by an industrial robot or other multiaxis CNC motion systems. The method in this invention includes the approaches and algorithms to detect the hole position, size, and orientation by using a vision system mounted on the robot arms. The hole orientation is determined based on the alignment of the vision system and the hole axis. The position of the hole is the intersection between the hole axis and the surface region around the hole opening.
