Ford engineers are using 3D mapping in what is believed to be the technology’s first application in the auto industry to better analyze rear axle parts of F-Series pickups during assembly, leading to a smoother, quieter ride for drivers of Ford trucks.

Similar to Google Earth, which uses three-dimensional imaging to map the world, Ford’s photogrammetric pattern reader (PPR) uses a pair of digital cameras to combine photos of the axle gears into a series of 3D pictures that are compared against an ideal computer model of the gears. Gears that don’t meet “Built Ford Tough” specifications are discarded.
