The invention relates to an electronic police. The invention particularly relates to a traffic electronic police snapshot control device and method. The device comprises a controller and an audio acquisition module used for acquiring road sound. The controller is connected with an audio identification module for identifying whether whistling audio exists in the road sound or not. The controller isconnected with a wave beam energy difference calculation module used for calculating a wave beam energy difference value in each linear direction in the audio acquisition module, and the wave beam energy difference calculation module is connected with a data analysis module. The controller is connected with a sound source position judgment module used for judging the position of a whistling soundsource according to a data analysis result. The controller is connected with a front face image acquisition module used for acquiring a front face image of a whistling vehicle, and the front face image acquisition module is connected with a license plate recognition module used for recognizing the license plate of the whistling vehicle according to the front face image of the whistling vehicle. According to the technical scheme provided by the invention, the defects that in the prior art, vehicle whistling snapshot is not accurate enough, and snapshot pictures are not clear enough can be effectively overcome.
