Abstract:
A system and method for calibrating the position of a machine having a stationary part to a stationary marker. The process first images the machine and the marker, and then identifies a visible part of the machine in the images that has been 3D modeled. The process then calculates a location of the stationary part of the machine using the modeled position of the visible part and the known kinematics and position of the machine. The process then identifies the stationary marker in the images, and establishes a relationship between the stationary marker and the stationary part of the machine, which can be used for calibration purposes. In one embodiment, the machine is a robot and the process is performed by an AR application.
