| titleOfInvention | Surface gathered water accumulated ice detection method and device |
| abstract | The invention discloses a kind of surface gathered water accumulated ice detection method and device.Wherein, the method includes: obtain the first road surface image frame that the road surface being in image pickup scope is photographed by the first video camera by horizontal polarizer；Obtain the second pavement image picture that the road surface being in image pickup scope is photographed by the second video camera by vertical polarizer, wherein, the camera plane of the imageing sensor (CCD) of the second video camera is coplanar with the camera plane of the CCD of the first video camera, and the distance between the second video camera and the first video camera is less than predetermined value；Judge whether the brightness of the first road surface image frame is more than the brightness range pre-set with the difference of the brightness of the second pavement image picture, if it is, judge that the road surface being in image pickup scope exists ponding or accumulated ice.By the invention it is possible to promote the use of on existing drive test video camera, and have that repacking is easy, recondition expense is low and on original system without the advantage of impact. |
