Surface Topography Reconstruction of Ring Components Based on Polarization Vision
In order to enhance the quality inspection of ring component surfaces,a FSV polarisation detection method based on a monocular DoFP polarisation camera was proposed.The FSV-based polarimetric 3D reconstruction model was calibrated based on the diffuse reflection information separated from the polarimetric reflections.Enhanced 2D surface images were obtained using the polarisati-on data and the corresponding polarisation 3D modelling was performed.The experimental results show that the DoP images measured by the proposed detection method are more than 3％better in terms of image evaluation index compared to conventional imaging systems and non-FSV polarisation imaging systems,and the root-mean-square error between the reconstructed 3D model and the real inspection surface is 0.35,which greatly improves the quality inspection capability of the ring components surface.
