The invention discloses a highway visibility detection method, system and device based on image multi-feature fusion, and a road fog visibility grade evaluation method based on image multi-feature fusion, obtains image features of a real-time monitoring picture of a highway, and constructs a support vector machine-based method. The method for classifying the visibility level of the fog fog can be used to evaluate the visibility of the highway in real time; the present invention does not require complicated operations such as camera calibration, setting targets in advance, etc., and does not require expensive visibility detection instruments, such as transmission-type or scattering-type visibility meters. ; Real-time detection of the visibility of Tongduo highways, which can effectively guide highway traffic and ensure highway traffic safety and people's life and property safety.
Description
【Technical field】 [0001] The invention belongs to the technical field of image processing, and relates to a road visibility detection method, system and device based on image multi-feature fusion. 【Background technique】 [0002] In recent years, the development of expressways has been particularly remarkable, which has greatly improved the highway traffic capacity and transportation efficiency, and promoted the sustainable and healthy development of the economy and society. But what followed was the increasing number of traffic accidents. According to statistics, traffic accidents caused by mass fog accounted for more than 1 / 4 of the total number of accidents, and the accident rate of expressways in foggy days was 10 times higher than usual. [0003] Fog mass is a local-scale atmospheric condition affected by the local microclimate environment. The characteristics of mass fog are: strong suddenness, covering a range of one kilometer to five kilometers, and low visibility wit...
