A New Method to Measure 3D Textile Defects by Using Dual-lens Camera

Résumé

Industrial textile fabric with functionalization always has a high standard requirement. Take polytetrafluoroethylene (PTFE) conveyor belt as an example, the base fabrics must be of first-rate quality, with no weaving faults or broken fibers on coated surface [1]. In a previous work, we have proposed an original method to measure the height of the fiber based on variable homography. This measurement is based on a single camera acquiring two successive frames. This scheme is working well, but measurement depends on conveyor speed used for scrolling fabric. In this paper, we propose an improvement by using a new acquisition device based on two mini-lenses assembled as a dual-objective. With this device, variable homography modeling leads to 3-D online inspection whatever fabric speed with a simplified calibration procedure compared to classic stereovision approaches.
