we use 3D laser scanning for global inspection of parts produced using
rapid prototyping and also to measure molds produced using rapid tooling or
equivalent.
We are developping an automatic process planning system for 3D laser
scanner in order to be able to directly and automatically generate the good
relative positions between the part (or the mold) and the scanner, and also
also the laser scanner path in order to minimize time consuming.
It is for a complete measurement process, in order to verify that the
obtain part (tool) is compatible with the initial CAD file, in a rapid
measurement way.

Best regards, and Happy new year to all list !
