Abstract:
Access control in general is a mechanism for limiting access to areas and resources based on personnel's identities and their membership in various predefined groups. Access to limited zones can be managed based on vehicle identification alone or together with personnel identity. In this project vehicle access control is provided through Automatic Number Plate Recognition System and personnel access control through the Radio Frequency Identification. Automatic Number Plate Recognition is an image processing technology, which uses number plate to identify the vehicle. Vehicle number plate region is extracted using image segmentation. Optical character recognition technique is used for the character recognition. MATLAB is used for the implementation of License Plate Detection algorithm. This system takes a vehicle image of any size and first of all extracts the number plate area from the image. The image is then given to the Optical Character Recognition module, which recognizes the characters and converts them in text format. Radio Frequency Identification tags are used for the identification of personnel at the entrance of the restricted area. The resulting data obtained through Automatic Number Plate Recognition and Radio Frequency Identification will be used to compare with the record in a database and if the data matches, only then the barrier will be raised and the gate will open at the entrance of the restricted area.
