Description
technical field [0001] The invention relates to the technical field of object detection, in particular to an object surface icing detection system. Background technique [0002] There are various object ice detection systems in the prior art. For example, based on the change of the polarization state of the reflected light after passing through the ice layer, it is determined whether there is an ice layer on the surface by detecting the brightness of the light passing through the analyzer. By actively emitting 1000-2000nm unpolarized near-infrared light to the road surface, the reflected light is received by three detectors located at the same height, with the same spacing and inclination to the ground, and polarizers in different directions are placed in front of the two detectors. No equipment is placed in front of a detector, and it is judged whether the road is icy by detecting the reflected light intensity. However, although the above-mentioned icing detection system c...
