Chromasens GmbH has developed a new kind of process for colour 3D surface measurement based on its self-developed, trilinear CCD line scan camera technology.

The system, that can be used in a variety of areas, is based on stereoscopic capturing and supports the capturing of almost any size object. Through the fusion of high-quality line scan camera systems and state-of-the-art graphic processor technology, altitude values can be captured and displayed with the highest precision in real-time using an image correlation process.

“The new measurement system for industrial use combines the advantages of customer-specific line scan cameras with proven 3D evaluation methods known from 3D matrix camera systems.”

An obvious application for the colour 3D process presented here is the matching of colour impression and shape on a 3D shape embossed print on the surface, e.g. in high-quality cosmetic packaging, toys or membrane keypads.

Further applications for 3D surface measurement include wood and wooden products, tiles, flagstones or veneered surfaces. Processed metallic surfaces can also be holohedrally measured with this solution. The first projects, e.g. in the quality control of leather, have already been achieved.

"Customers can turn to us with their measurement tasks. By an analytical pre-evaluation of the respective object surface, Chromasens can suggest a suitable camera system with the right sensors, lenses and illumination that is optimally suited to that measurement task," says Markus Schnitzlein, inviting interested parties to try out the new 3D surface measurement process.
