Photogrammetry, CAD-based inspection bring speed, accuracy to helicopter panel assembly
The larger things are, the more challenging they are to inspect. Traditionally there were only two choices--bringing the measuring system to the parts or taking the parts to the measuring system. Now, this problem is being solved by combining two proven dimensional-measurement technologies--photogrammetry and CAD-based inspection. The result is a new type of coordinate measuring machine (CMM).
Neither of the original options for measuring large objects was very appealing from a productivity standpoint. Moving the measuring system to the part requires recalibration. At ...
