The invention discloses a vehicle whistling recognition and positioning system and method. The system comprises a sound acquisition module, a sound processing module, a sound recognition module, a MUSIC sound source positioning module, a license plate recognition module and an identity confirmation module. According to the invention, the spherical sound array is adopted to collect the sound on the road from multiple angles; performing framing windowing preprocessing on the collected sound to obtain smooth and continuous sound, and extracting the characteristics of the sound by using a harmonic impact source separation method; a classifier model combining a bidirectional peephole network and a residual network is designed, a classifier is trained by using a large amount of vehicle whistling sound, and then road sound is identified; and the identified whistling sound is positioned by using a MUSIC method, the license plate of the vehicle is photographed and identified, and finally the identity of the vehicle owner is determined for law enforcement officers to punish the vehicle owner. Compared with a traditional vehicle whistling recognition and positioning system and method, the vehicle whistling recognition and positioning system and method have higher whistling recognition rate and more accurate positioning.

    本发明公开了一种车辆鸣笛识别定位系统及方法,包括:声音采集模块、声音处理模块、声音识别模块、MUSIC声源定位模块、车牌识别模块和确认身份模块。本发明采用球形声阵列多角度采集道路上的声音;对采集的声音进行分帧加窗预处理,得到平滑连续的声音,使用谐波冲击源分离方法提取声音的特征;设计了双向窥视孔网络和残差网络相结合的分类器模型,并使用大量车辆鸣笛声音对分类器进行训练,然后对道路声音进行识别;对识别到的鸣笛声音使用MUSIC方法进行定位,并对该车辆的车牌进行拍照识别,最后确定车主的身份,供执法人员对其进行处罚。本发明与传统的车辆鸣笛识别定位系统及方法相比,有着更高的鸣笛声音识别率和更准确的定位。
