Abstract

The invention discloses a high-definition camera-based method and system for pavement event detection. A detection region is divided into three regions; and different vehicle locating methods and license plate locating methods are used in the three regions. A detection method containing a confidence degree and a weight is applied to the event detection for the first time. Therefore, not only the problem of incomplete detection caused by too narrow high-definition license plate recognition region is solved, but also the detection precision can be greatly improved, and the false alarm rate is reduced.

Description

technical field [0001] The present invention relates to the field of road surface traffic event detection, in particular to the real-time detection of various traffic events on a wide range of road surface, specifically a method and system for detecting road surface events based on a high-definition camera. Background technique [0002] In order to prevent various accidents on the expressway and respond to emergency treatment of various emergencies, the highway pavement incident detection system is especially useful in early warning of road incidents, real-time alarm of road accidents, and prevention of secondary accidents. Great significance. [0003] At present, the traffic incident detector is still mainly based on large-scale simple incident detection. The main problems are: due to the large detection range, the detection is subject to environmental interference factors. Although many excellent algorithms can largely compensate for various sunshine, However, the increas...
