Urban road-based illegal parking vehicle detection and management method and system

The invention provides an urban road-based illegal parking vehicle detection and management method and system. The detection method comprises the following steps of obtaining continuous frames of monitoring video images and selecting a monitoring area; detecting the vehicle coordinate data and the license plate number of the vehicle in the monitoring area in the continuous frames of monitoring video images, and determining that the vehicle is an illegal parking vehicle if the deviation value of the vehicle coordinate data of the vehicle corresponding to the same license plate number is smallerthan a position threshold value and the vehicle is in a no-parking area corresponding to the monitoring area; if the vehicle is in the temporary parking area corresponding to the monitoring area, carrying out face detection and parking duration statistics on the vehicle, if the conditions that a face is detected and the parking duration is smaller than a duration threshold value are met at the same time, indicating that
