The present disclosure discloses a vehicle tail light recognition method, device and vehicle. The method includes: identifying the tail light of a first target vehicle according to the collected historical front-of-vehicle images; and determining the first target according to the recognition result The historical position area of the taillight of the vehicle in the historical front image; according to the historical position area, using a preset model to predict the position of the taillight of the first target vehicle in the collected current front image , to obtain a target detection area; in the target detection area of the current front image, identify the tail light of the first target vehicle, so as to obtain the current information of the tail light of the first target vehicle. This disclosure utilizes the historical position area of the vehicle tail light to predict the vehicle tail light position area of the current front image to obtain the target detection area, and only recognizes the vehicle tail light in the target detection area, so as to reduce the amount of calculation, improve the detection efficiency and improve the real-time performance Effect.
Description
technical field [0001] The present disclosure relates to the field of intelligent transportation systems, in particular, to a vehicle tail light recognition method, device and vehicle. Background technique [0002] With the rapid development of science and technology, in the field of intelligent transportation systems, the ability to identify road surfaces can be improved by detecting vehicles ahead, especially when driving at night when the road traffic environment is complex, giving drivers more It has become an important direction for the development of this field to improve the active safety of vehicles. [0003] At present, the identification of the vehicle ahead in the night driving environment is generally realized by identifying the tail lights of the front vehicle. In related technologies, for the identification of vehicle taillights, the characteristics of vehicle taillights are usually used to formulate corresponding extraction and matching rules, and the taillig...
