Optical Tracking System

The presented optical tracking system allows intuitive controlling and programming of industrial robots by demonstration. The system is engineered with low cost components. Using an active marker (IR-LEDs) in combination with a stereo vision configuration of the camera system and the selection of suitable algorithms for the process chain of the image processing a positioning accuracy in the range of millimeters has been achieved. The communication between the tracking system and the robot is realized by using the TCP/IP protocol via an Ethernet connection.
