The invention discloses a false alarm prevention method for a vehicle whistling snapshot system. The method comprises the following steps: pre-establishing a feature library of a corresponding relationship between a vehicle model and whistling feature reference data; when a whistling behavior of a preset monitoring area is detected, determining a whistling position of the whistling behavior through a sound source positioning technology; a video image of a target vehicle is obtained, the license plate number of the target vehicle is recognized according to the video image, the target vehicle is a vehicle located at the whistling position during the whistling behavior, and the target vehicle is a vehicle; querying a corresponding vehicle model from a vehicle management system according to the license plate number; matching a whistling sound signal of the whistling behavior with the corresponding vehicle model based on the feature library; and if yes, determining that the target vehicle has the whistling behavior. The method not only can be used for more accurately judging whether the target vehicle has the whistling behavior, but also can be used for identifying the abnormal whistling behavior.

    本发明公开了一种用于车辆鸣笛抓拍系统防误报的方法。所述方法包括:预先建立车辆型号与笛声特征参考数据对应关系的特征库;当检测到预设监控区域的鸣笛行为时,通过声源定位技术确定所述鸣笛行为的鸣笛位置;获取目标车辆的视频图像,并且根据所述视频图像识别所述目标车辆的车牌号码,所述目标车辆为所述鸣笛行为时处于所述鸣笛位置的车辆,所述目标车辆是一个车辆;根据所述车牌号码向车辆管理系统查询对应的车辆型号;基于所述特征库将所述鸣笛行为的鸣笛声音信号与所述对应的车辆型号进行匹配;若相匹配,则确定所述目标车辆存在所述鸣笛行为。本方法既可以用于更准确地判断目标车辆是否存在鸣笛行为,还可以用于识别异常鸣笛行为。
