The invention relates to a device for producing a pattern on a surface for measuring, using a projector and a slide. The invention also relates to various advantageous embodiments of the measuring system.

System for measuring the surface geometry and surface evenness of flat products

The invention relates to a method and a device for optically measuring the surface shape and for the optical surface inspection of moving elongated bodies, according to which surface shape measurement and surface inspection are integrated. A projector applies a line pattern to the object to be measured. A camera registers the surface of the object to be measured and compares the image information with a reference pattern. Two high-resolution cameras additionally detect surface defects on the object to be measured. The inventive measuring technique is especially suitable for a combined planarity and surface measurement of metal strips in rolling installations.

Method and device for optically measuring the surface shape and for the optical surface inspection of moving strips in rolling and processing installations

The invention relates to a flatness measurement and control system for metal strip, which makes it possible to obtain improved strip or coil quality by a simple and effective measurement of departures from flatness and to control the finishing parameters through the evaluation of a line pattern on the strip surface or on the end face of a coil as it is coiled.
