摘要: We present the problems faced in design of an artificial vision inspection system metallic tubes and solutions adopted. propose a theoretical model image acquisition discuss signal processing case continuously moving products: influence period, resolution, movements defect size on detection scattering; signal-to-noise ratios are estimated. Finally, we some results obtained production line. Our solution is based use set linear CCD cameras, ensuring achievement 2D image. The tint can be detected by using two different view angles. introduction angular correction reduces scattering responses. calculation parameters low level language enables us to perform real time inspection. >
