Abstract
- A system of obtaining image of surface of wire rope is designed in this paper. Three linear-array charge-coupled device industrial cameras are used, separated by 120 degrees in the same plane. The acquisition is realized by receiving the synchronous pulse transmitted by the encoder. Considering that the wire rope is bent due to gravity, this paper restores the wire rope to the straightened state through image processing. The wire rope is then separated from the image. In order to obtain a complete surface unrolling diagram, this paper firstly corrects the projection of curved surface of image of the wire rope. Three unrolling diagrams of surface of wire rope with different angles are obtained, and then, the surface development image with different directions is aligned in axial and circumferential directions, respectively. At last, weighted average algorithm is used for image fusion. The experimental results show that the method proposed in this paper can obtain a complete, intuitive and non-dislocation surface development image of wire rope. [ABSTRACT FROM AUTHOR]
