Raspberry pi ve python ile gerçek zamanli plaka tanima sistemi

In order to provide reliable transportation with the increasing traffic density in the current time, it is necessary to detect dangerous situations with video analysis by using camera and remote control system. One such analysis is Automatic License Plate Recognition. Automatic license plate recognition systems consist of algorithms such as license plate detection, edge detection, character segmentation and optical character recognition. With the license plate recognition system developed in this thesis, after preprocessing the license plate image taken from the camera with image processing algorithms, license plate recognition has been made with the deep learning algorithm and the recognized license plate information has been sent to the defined e-mail address. In the developed license plate recognition system, Raspberry Pi, called mini computer, has been utilized as hardware, and the software has been developed in Python programming language. From edge detection methods; the performances of Canny, Fuzzy, Roberts, Sobel and Prewitt methods on the license plate recognition system were measured and the performance of the Canny edge detection method was found to be high and the algorithm of this method was embedded in the license plate recognition system. As a final step, Tesseract optical character recognition has been performed by scaling the frame. After recognition, a comparison has been made with the characters defined in the deep learning structure and the license plate recognition process has been completed. Tests were carried out to evaluate the developed license plate recognition system. As a result of these tests, the average accuracy rate of the system was 91.67% in real-time license plate recognition and edge detection, and 89.43% in character recognition. With the developed license plate recognition system, low cost and high accuracy recognition will be achieved.
