Checking shape and dimensional accuracy is an important part of quality control in industrial manufacturing. In the field of machine vision in particular, special test methods and techniques are often used to ensure compliance with tolerances and dimensional specifications.

One way to check form and dimensional accuracy is to use optical measuring methods, in which the part to be checked is photographed with a camera and the dimensions are automatically determined using image processing software. The advantage of this method is that it is fast, accurate and does not require physical contact with the part.

Alternatively, non-contact 3D scanners can also be used to measure the shape of the part. These methods are particularly suitable for checking complex geometries and for monitoring production processes in real time.
