Automatic doorstop safety system based on image processing using webcam and scanner

In this paper has been studied about design of safety system for prevent thievery vehicle at parking area and implemented at miniature. This system consisted of camera from webcam at entrance gate, main computer at center and scanner at portal gate. The image of plate taken by webcam processed by computer using Open Source Computer Visual (OpenCV) library who have Optical Character recognition (OCR) and tesseract function till became string data and finally saved in database at computer via XAMPP - MySQL. After string data saved in database the program generate audio signal as input who processed by Analog to Digital Converter (ADC) at microcontroller ATMEGA8535 for finally moving servo motor as automatic bar at entrance gate. The data which already saved at database in computer is ready to be checked at portal gate side which if string data taken by scanner from vehicle registration certificate is match with data who saved in database, the automatic bar at portal gate would be opened with the same method from automatic bar at entrance gate otherwise it the automatic bar at portal gate wouldn´t active.
