Example 15: Automotive Seats
Click on an image to enlarge
Problem: To inspect automotive seating for the purpose of ‘in-vehicle’ clearance
studies. These seats were provided in both cloth as well as leather seating surface configurations.
Process: A large volume CMM fitted with a laser sensor was used to digitize each seat.
This large CMM measuring capacity allowed for multiple seats to be digitized at the same time. In order to
obtain all of the 3-Dimensional information, the model was digitized from a number of different
orientations which were all later associated together into the same coordinate system.
Solution: The multiple scans of the seats were associated together into the same
coordinate system using common references. Once associated together, the entire scan was then aligned to
‘car-body’ position using customer specified datum features. Planar sections were then cut through the
dense measured data for final delivery to the customer. These sections were exported in IGES format for
translation into most any mainstream CAD / CAM software package.
