trevista® DOME

The intelligent illumination components of the trevista® product range enable surface inspection in a new dimension. The patented unit is based on a special Shape from Shading algorithm. With its unique technology, it is the reference for 2.5D inspection. trevista® DOME is perfectly suited for the automated inspection of technical and decorative surfaces in the industrial environment.

Thanks to the shape-from-shading technology, trevista® DOME “sees” more compared to classic image-processing inspection systems since it represents the surface shape of the inspection objects plastically and makes even defects in the micrometer range visible. With its standardized illumination method, trevista® DOME can be used flexibly as a plug-and-play system for a multitude of tasks.

High inspection speed enables 100% inspection with a high parts throughput.

Shape from Shading: See What's Really There.

The trevista® process is based on a patented “shape from shading” technology, which means that information about the three-dimensional shape of an object can be obtained from the shading of surfaces. The surface to be tested is diffusely illuminated by means of a hemispherical scattering body. From several input images, a special algorithm calculates high-quality result images for the subsequent automatic evaluation.

The Image – The Basis for Every Successful Image Processing Solution

By combining the result images in different ways, the inspection objects can be checked reliably and flexibly for various defect characteristics.
