The addition of the new ABIS II contrast sensor system allows quickly and easily extending the range of detectable defects to include surface characteristics that are not visible in the 3D image. With the contrast sensor system, bar-shaped LED lines and the camera are customized for the field of view and the measurement distance of the ABIS II sensor. The images are captured almost simultaneously by the ABIS II sensor and the contrast sensor system (time difference 0.1 msec), so that the overall inspection time for component testing is not prolonged when using the contrast sensor system.

To ensure exact positioning of the part under test, an optional laser beamer can indicate the part‘s contour on the measuring table of an ABIS II Offline system (see bottom picture on page 14). The position of the part on the table can be determined using an optical position recognition system. This data is then used to correct the robot path during the test procedure. The camera of the position recognition system can be installed either above the measuring table or directly to the robot.

The robust, industrial strength design of the sensors ensures a reliable, high-speed measurement data acquisition in press shop and body shop environments: The ABIS II sensors are not affected by high acceleration loads, vibration, hall lighting, fluctuating temperatures, etc., which they are exposed to on site every day.
