Research On Key Technique Of Computer-vision Surface Inspection System For Cold Rolled Strips

With the development of the computer-vision and computer capacity, automatic strip surface inspection based on image has become favorable question for study. This peper proposes automatic strip inspection system, and finishes the development acquiring image, pre-processing image, analyzing and dispelling noisy, inspecting and cuting apart defect. The paper researches the technique of shape recover from shading and network. The main content and achivement of this paper are listed as follows:1.According to inspection system's technical requirement, its overall design plan is put forward. It includes hardware and software design scheme.2.Advancing the method for acquiring image with VFW.3.Putting forward the method for the acquirement the noisy image, finding the noisy's character and advancing the intelligencal method for dispelling noisy.4.With the research of the defect's character, putting forward the method of defect recognition and cut apart.5.Researching the shape from shading and putting forward the shape from shading neural algorithm.6.Putting forward the design scheme about local area network's hardware and software.Test result shows the technologies are effective.
