The challenge

The position of the holes on every car door had to be measured, and the deviations had to be tracked over time.

Our solution

The camera images the hole at the four measuring points on the door in turn. Our software locates the hole and reports its position deviation on two axes (H and L) in millimeters; each image is checked in under half a second.

The latest measurement of each point is shown on screen and its history in trend charts, and the images are saved. When there is no door at the station, the system shows a "No door" warning.
