Abstract
This paper describes an automated visual inspection system for the size measurement of workpieces, widely applicable to industrial on-line and real-time products inspection such as bearing, gear and so on. The systematic makeup, basis demands and CCD-based size measurement principle is introduced. To increase the efficiency and effect of pre-processing image, take a bearing as an example, fast algorithm for 2-D median filter is advanced and investigated. Also, based on the fundamental theory of the wavelet transform, an edge detection method is successfully used in the feature extraction of a bearing image. Finally, with the studied automated visual inspection system, the out-diameter of a bearing is inspected and analyzed. The result meets demands and shows the system has a broad applied foreground
