The invention provides a method, device and system for detecting a modified vehicle. The method comprises the following steps of based on a collected sound signal, obtaining a first position of a target sound source emitting a roar signal; identifying a target vehicle of which the coincidence degree of the vehicle position and the first position is smaller than a coincidence degree threshold valuefrom acquired video images; identifying vehicle features of the target vehicle; and determining whether the target vehicle is a refitted vehicle based on the vehicle characteristics. The method is advantaged in that the refitted vehicle can be detected efficiently at low cost.

    本申请提一种检测改装车辆的方法、装置及系统。其中,方法包括:基于采集到的声音信号,获得发出轰鸣声信号的目标声源的第一位置;从采集到的视频图像中,识别出车辆位置与所述第一位置的重合度小于重合度阈值的目标车辆;识别所述目标车辆的车辆特征;基于所述车辆特征,确定所述目标车辆是否为改装车辆。如此,可以高效、低成本的实现对改装车辆的检测。
