Lacks of visibility detection (fog, rain, …) by Computer Vision
 |
. Detects when visibility conditions are not appropriate to camera-based detection (reliability of detection and sensor fusion : if Visibility is poor, do not trust camera-based detection), and also when driver is not good at detection (adapted HMI to bring trust in the cockpit)

Lines give distance of visibility. Color spots estimate if quantity of information inside the area is usable or not to do objects detection (theory of detection), with human eye and brain, or with computer vision detectors. When all colour spots are red, visibility is inappropriate to computer vision based detection and you know it ! (you can react properly in case of « white truck on a white sky background ») |
