Automatic Parking System is a parking solution designed for the modern establishments that want to manage their parking lot without human assistance. The proposed system consists of fully automated toll gates that control the entry and exit of the vechicles into and from the parking lot. It also features the ability to restrict the entry of blacklisted cars. The live status of the parking slots can be viewed through a mobile application designed for the system admins. The number plates of the cars are recorded on their entry/exit using OCR. The timing of their entry/exit, number plates and the number of empty slots are recorded and stored in database on every operation of the toll gates.
