Our world is made in 3D and therefore most of the tasks for vision systems
relate to the shape of objects. Traditional vision systems work on 2D
images. There is an unsatisfactory fact for the engineer that he gets
deviations of the shape only in some manner as modulation of gray-values.
This may result in laborious software-engineering and unreliable solutions.
We overcome these problems with our 3D-measuring principle by providing
additionally x-, y- and z-coordinates to all the pixels in the images. |
Imagine you have to control the letters and symbols of the coin below.
2D image of a used coin.

Image in depth (z-values) of the same coin at the same point of view.
