  • Patent number: 11145205
    Abstract: A system and method for addressing roadside parking issues are provided. The method includes: determining whether a parking fee has been paid for an on-street parking space, and if not, activating a detector of the corresponding parking meter; determining whether an object exists in the parking space and whether the object, if existing, is a vehicle, and if yes to both, activating a camera of the parking meter to obtain an image of the parking space; determining again whether the object is a vehicle by performing image and license plate recognition, and if yes, either prompting a parking enforcement officer to go to the parking space and issue a parking ticket or issuing the parking ticket automatically; updating the parking meter after the parking ticket is issued; and reducing the detection frequency. The method is labor-saving and reduces power consumption by the parking meter.
