Outline
In the paper, it is proposed the method of detecting such problems as tearing, surface tears, edge damages and foreign matters of materials for travelling belt adopting 3D vision technology in such industries as mining and metallurgy, elaborated the technical principles and detection algorithms of detecting surface defects for travelling belt based on 3D vision technology as well as described the design and installation way of visual image acquisition device suitable for dusty working environment. The detection system of surface deterioration trend and tearing for travelling belt is suitable for such operation environments of transporting large-scale bulk material as steel metallurgy and ports. It has been in operations in steel enterprises for two years, during which the surface tears of travelling belt are detected timely and accurately so that further expansion of faults is avoided and good effects are achieved.
