Glare suppressed 3D mapping system based on linear polarization filtering and binocular vision fusion

To address the problem of large errors in 3D maps caused by mismatching due to white flares formed through specular reflections on smooth object surfaces during digital image acquisition, we propose applying the polarization principle to filter out the orthogonally polarized component of linearly polarized light in the reflected light, thereby reducing or eliminating the white flare area. The experimental results demonstrate that the system can effectively suppress the flare intensity on nonmetallic surfaces, which mitigates artifacts in 3D reconstruction.
