Abstract
A gear inspection system and method for a gearbox, wherein an image acquisition unit is oriented proximate the gearbox with a field of view of a section of the gears. The image acquisition unit obtains images of a gear tooth and corresponding contact pattern. In one embodiment a processing unit transforms the images to a gear tooth model so that the gear tooth image and contact pattern image matches the model gear tooth. Metrics are computed for the contact pattern, and based on threshold values, a determination is made as to whether the gearbox is acceptable.
