Abstract :
Sheet metal is often used for components which, for functional reasons or visual effects, have to meet high requirements concerning form accuracy as well as smooth surface curvature, while dimensional errors are of minor significance. In this paper a measuring system which allows automatic detection of waviness and form errors is presented. The system is based on a stripe projection method using a high resolution line scan camera. Particular focus is put on achieving both short measuring times and high resolution in depth, aiming at reliable automatic recognition of dents and waviness of only 10 μm depth within less than 10 seconds per m2.
