pip install pytesseractĪfter this, install the PYTTSX3 library for text to speech conversion using the below command: pip install pyttsx3 sudo apt-get install tesseract-ocrĪfter that, install the pytesseract using the pip. SMTP Mail Setup for Raspberry Pi Car Plate Recognition Use the below command to install the imutils: pip3 install imutils Imutils is used to make essential image processing functions such as translation, rotation, resizing, skeletonization, and displaying Matplotlib images easier with OpenCV. SMTP (Simple Mail Transfer Protocol) is the standard protocol for providing email services on a TCP/IP network. This server provides the ability to receive and send email messages. We are using SMTP to send a mail when the Raspberry Pi detects and recognizes a license plate. Use the below command to install the same: sudo apt-get install ssmtp To use the SMTP services on Raspberry Pi, we first have to install the SMTP library on Pi. Don’t forget to add your email and email Programming for Number Plate Recognition using Raspberry Pi For that, open Configuration file using the below command: sudo nano /etc/ssmtp/nfĪnd add the below lines. License plate recognition OpenCV python code involves three major steps. The first step is License Plate Detection. The contour function will be used to detect the rectangular objects in the image to find the number plate. The second step is Character Segmentation. Once Contour detects the License Plate, we have to crop it out and save it as a new image. And the final step is Character Recognition. We will perform Optical Character Recognition on the cropped image to detect the number.Ĭomplete Number Plate Recognition code in python is given at the end of the page.
