Calibrating a vision system into car frame

A new model must first be set up in the ISRA system before it can be integrated into the line. Up to now, the relationship between the vehicle and the robot has been measured using a laser tracker. An external service provider was necessary for this work. In the future, the customer wants to carry out this work on his own with the help of the LaserLAB and the base:in software.

Four measuring balls are attached to the car body with corresponding adapters. The positions of these balls are measured in the measurement house relative to the vehicle zero point. The measuring body is then moved into the production cell and measured with each robot in turn. The result is the base transformation body – robot. This is transmitted to the robot. The measurement body is measured with the ISRA system at the same position where it was measured with the robots and stored as a so-called zero measurement. In the future, the ISRA system will determine the offset of the current body to the zero body and perform a base correction of the robots.
