The invention discloses a vehicle whistling detection system and method, which are used for improving the accuracy of vehicle whistling detection. The system comprises acoustic equipment, camera equipment, road test equipment and processing equipment. The acoustic equipment is used for acquiring sound in a detection range and detecting a vehicle, and determining whistling sound information, distance information of the vehicle making whistling sound and corresponding timestamp information; the camera equipment is used for receiving the distance information and the corresponding timestamp information, determining camera shooting data acquired by the camera equipment corresponding to the timestamp information, analyzing and processing the camera shooting data according to the distance information, and determining structured information of the whistling vehicle; the road test equipment is used for collecting vehicle driving state information broadcasted by a vehicle-mounted unit of the vehicle after the vehicle whistles; and the processing equipment is used for determining whether the whistling vehicle has a whistling phenomenon or not based on whether the license plate information and the time period information in the structured information and the vehicle driving state information of the whistling vehicle are matched or not.
Description
technical field [0001] The invention relates to the technical field of traffic monitoring, in particular to a vehicle whistle detection system and method. Background technique [0002] At present, with the continuous advancement of urban modernization and the continuous improvement of people's living standards, the number of cars is also increasing year by year, so there are often traffic jams on urban roads, causing car drivers to honk their horns in residential areas or core areas. The living environment of the residents is noisy, affecting the rest of the residents. [0003] Moreover, in the prior art, the distance between vehicles is small, which leads to low detection accuracy of the vehicle whistle. To solve this problem, in the prior art, the distance between vehicles is reduced by adding speed bumps in the supervision road section. The spacing is widened to reduce vehicle overlap and improve detection accuracy. However, this way not only needs to set speed bumps, b...
