Abstract: A method of providing a parking service comprises calculating overlap degree of a target vehicle and specific parking area by analyzing a parking monitoring image obtained from a sensor for monitoring specific parking area at a first time of point and determining through the calculated overlap degree whether the target vehicle is parked; recording the target vehicle in an exit queue when the target vehicle goes out of the specific parking area by analyzing a parking monitoring image obtained from the sensor at a second time of point; performing an exit process when the target vehicle included in the exit queue moves to go out of the specific parking area by analyzing a parking monitoring image obtained from the sensor at a third time of point. A payment process in accordance with an exit of the target vehicle is performed based on payment information preregistered when the target vehicle is parked.
