Method and system for positioning whistling vehicle based on audio and video coupling

The invention discloses a whistling vehicle positioning method and system based on audio and video coupling. The method comprises the following steps: firstly, acquiring to-be-analyzed audio data and to-be-analyzed video data; extracting time domain features and frequency domain features of the to-be-analyzed audio data, and performing identification according to the time domain features and the frequency domain features to obtain audio clips of whistling sound; determining a sound source direction of the whistling sound according to the audio clip of the whistling sound; determining the position of a whistling vehicle according to the to-be-analyzed video data; and finally, determining information of the whistling vehicle according to the sound source direction and the position of the whistling vehicle. The method is low in cost, small in calculation amount and high in accuracy, and can be widely applied to the technical field of computers. 本发明公开了一种基于音视频耦合的鸣笛车辆定位方法及系统，方法包括：首先获取待分析音频数据和待分析视频数据；接着提取所述待分析音频数据的时
