ABSTRACT:
For computing the absolute height, in a field of view of a CCD-based acquisition system, of the profile of an object moving on an assembly line, two CCD-based image acquisition devices are used. The consecutive acquired images of the two CCD-based image acquisition devices are shifted by a predefined number of lines. Using two relative heights, the absolute height of a feature located in the acquired images is computed.
