Abstract
This paper describes a computer vision system for the high-precision inspection of bearing shells. We have developed algorithms to solve the problem of inspecting the wearing surfaces of sputter-coated metal shells for surface defects (high spots, cavities, blisters, grooves, and pores). The quality goal to be achieved was 0.3 m2/h, which for a typical 90 mm bearing shell being measured would mean about 0.5 minutes/shell. The resolution to be achieved was of each pixel covering an area of 24 micrometers by 24 micrometers . The analysis method was based on gray-scale rather than a binary algorithm. The quality standards were those defined by the Motoren and Turbinen- Union GmbH, Germany, and Daimler-Benz AG.
