Door Unlock System for Registered Vehicle Using Optical Character Recognition (OCR)

Abstract

The exponential growth in the number of vehicles used in cities and towns is leading to management overhead of vehicles. So for a guard in any premise or in the toll road people have to check the vehicle plate and decide whether vehicle is authorized to go through or not. So all of this takes plenty of human efforts and time to lock and unlock manually again and again. This paper deals with those vehicles which are already registered under any home or any organization. When any registered vehicle comes in front of the door the camera is attached to the door which will read the vehicle plate number. Then Raspberry pi 3 board with Raspbian OS in which camera and DC motor are attached where the OCR(Optical Character Recognition) algorithm along with rest of the python code that will detect the vehicle plate in machine readable language and later the decision will be made whether to open the door or to keep it closed. Soit provides solution in those fields where the registered vehicle of any organization routinely arrives and departs. So every time guard will no longer has to stay on the door to verify. Also the entry time of the vehicle would be saved in the database and would therefore help the people at higher posts to know about when a particular employee entered the office, if he was on time or was he late. It would also save the exit time of that vehicle in the database when the vehicle leaves the premises and it would thus help in maintaining the proper system.
