The invention discloses a black smoke vehicle license plate recognition method, a black smoke vehicle license plate recognition method system, a device and a readable storage medium. The method comprises the following steps of: collecting the exhaust emission factor of a detected motor vehicle driving on a road so as to obtain the discharged smoke intensity value of the detected motor vehicle; comparing the obtained discharged smoke intensity value with a discharged smoke intensity threshold value preset in a discharged smoke intensity database, and recognizing a black smoke vehicle; capturingthe vehicle driving video of the recognized black smoke vehicle; and carrying out image processing on the captured vehicle video to obtain the license plate information of the black smoke vehicle. With the black smoke vehicle license plate recognition method, the black smoke vehicle license plate recognition method system, the device and the readable storage medium adopted, the license plate of the black smoke vehicle can be accurately recognized. The method and system have the advantages of wide detection range, high test speed, high monitoring precision and low routine maintenance cost.
