Method and apparatus for recognizing and evaluating environmental impact based on road condition and weather

摘要

The present invention relates to a method of classifying road surface conditions based on image data of an in vehicle camera system, and an on-board camera system corresponding thereto.This method isHaving the following steps: - by an in vehicle camera system configured to depict at least one area outside the vehicleSteps for providing image data (S12)HoweverTheAt least partiallyThe vehicle contains the lane running;- the difference between at least one point on the roadStep S14: distinguishing scattered and specular reflections on the road by evaluating at least two images of the camera system;HoweverA rough image isTaken from different shooting points;- at least one image of the camera systemAt least one tire of the vehicleStep (16) to find out if there is any obstacle caused by winding up the road cover in rolling- in the following five road state classes, considering reflection types and failure level resultsClassification of road conditions (S18);Dried road surface: reflection type: scatter, no damageB) normally wet road: reflection type: specular, obstacleC) very wet road, hydroplaning risk: reflex type: mirror, obstacleSurface covered with snow: reflection type: scattering and obstacleFrozen road surface
