  • Corrosion evaluations on car rims or wheel segments, as well as on corrosion test panels
  • Partial scanning of installed parts on cars, e.g. wheels, doors, bumpers, etc.
  • Imaging and optical quality control of any kind of coatings
For more information refer to the robot-guided line scan camera and the Corrosion Inspector.


The robot-guided line scan camera with integrated corrosion inspection can be used to evaluate corrosion on car rims or wheel segments or other curved surfaces. Just as with the Corrosion Inspector it provides automatic and interactive measurement of corrosion phenomena, like area, width, filament length, red rust, delamination, multi-impact.

Exhibition setup

A sensor head consisting of a high-resolution line scan camera (monochrome or color) with integrated line illumination is mounted on a robot arm. The robot arm executes a scanning movement on a programmed path over the surface. The path programming is easy possible by manually setting of few way points. During the movement, the line signals are assembled one by one into a 2D image. The computer displays the final image on the monitor. The image processing and evaluation can be applied to the entire image after the scan is finished, or frame-by-frame already during the scanning process.

Unlimited freedom with high safety

Thanks to a 6-axis robot arm, there are almost no limits to the scanning of surfaces. Whether strongly curved, slightly twisted or a flat surface - all this is no handicap for the robot arm. This great freedom is supported by intuitive operation for creating the path for the scanning process. Waypoints can be set either by hand or in an easy-to-use software interface. When using the software interface, the robot arm can be controlled with high precision in both the position and angle of the sensor head.
The operator also benefits from the high safety of the robot arm thanks to force-torque sensors that comply with the standards DIN EN ISO 10218-1 as well as the requirements of DIN ISO/TS 15066. If too much force is applied, the robot arm switches off automatically. The operator must manually confirm the safety status in order for the robot to resume its work. This ensures safe operation in cooperation with humans.

Automatic Evaluation

Automated evalution of various corrosion parameters of different scribe pattern. Among other things, the infiltration area, the average infiltration width, length and number of threads are evaluated.
