Note: SRI Project 8487, 8059, 8121. This work partially supported by the NSF under Grant 14-08-0001-17296, by Lockheed-California under PO ALJ2N9530E, and by Lockheed-Georgia PO RT88798 and contract F33615-78-R-5008.
The SRI Vision Module has been tested for its ability to provide dimensional measurements on a sample aircraft subassembly. The parameters measured were the upset diameter of a rivet, and the distance from the center of a upset head to a stiffener edge. A total of 37 rivets were measured, using a dial caliper and the Vision Module.
