Fraunhofer Vision Guideline Series

Knowing about the possibilities and limitations of the latest technologies is an important prerequisite for the successful implementation of image processing in the production.

The Fraunhofer Vision guideline series wants to contribute to this goal. We release one volume per year, each volume dealing with one specific topic in the field of industrial image processing and describing the potential of the technology in several areas of application as simply and concretely as possible, in order to facilitate access to the topic for potential users.

Optical 3D Measurement

The exact observation of geometric dimensions is very important for the quality assurance in production and manufacturing. The measuring with mechanical gauges or coordinate measuring machines is time-consuming and thus can only be performed on some samples. A lot of tasks can be resolved much faster with contactless optical measurement.

Optical measurement systems support the development and qualification of new products, secure and objectify production processes and enable fast quality control loops in the production cycle. Furthermore, it is nowadays possible to measure with high accuracy the structures inside an object made out of nearly every material.
