System and method for navigation assistance in a scattering environment |
摘要 |
For performing navigation assistance in a scattering environment, a system is intended to detect at least one navigational light marker in scenes captured by an image capturing device, each navigational light marker generating a light beam having a predefined polarization state. The system includes an image capturing device that is adapted for: capturing a first image of a scene, said first image being polarized in accordance with the predefined polarization state of the light beam generated by said navigational light marker(s); capturing a second image of the scene, said second image being polarized according to a polarization state orthogonal to the polarization state of the first image; generating a polarimetric contrast image by combining the first and second captured images; and providing a feedback for performing navigation assistance in the scattering environment, on the basis of the generated polarimetric contrast image. |
