Cloud Capturing System Based on Computer Vision for Inner-surface of Pipe Figure Components

In order to capture the inner-surface cloud of pipe figure components with different material rapidly and efficiently, a new cloud capturing system based on computer vision for inner-surface of pipe figure components was designed. Firstly, the IIRDL (Integrated Inner-reflection Ringy Discrete Laser-spot) method was proposed, which combined the merits of the LSS (Laser Single-spot Scanning) method, the IRLS (Integrated Ringy Laser Section) method, the DRLS (Distributed Ringy Laser Section) method and the DRDL (Distributed Ringy Discrete Laser-spot) method, while overcoming the weakness of them. At the same time, the measurement arm employed the new method as the core of the capturing system was designed. Secondly, on the basis of the new measurement arm the whole capturing system was constructed. At last, the real 3D mathematical model for the capturing system was built. The new system based on the new method could complete the cloud capturing for inner-surface of pipe figure components rapidly and efficiently in experiments, which demonstrated good stability, and high precision.
