putText(image, display_message, (rect_points, rect_points), cv2. decode( 'utf-8')ĭisplay_message = "Access Granted" polygon_points = np. We will start by importing the needed libraries and setting up the webcam camera for video capture. Now, let us implement that by building an authentication and identification system to detect authorized and unauthorized personnel. Most employees in various companies and students in schools get access to specific areas by scanning their identification cards or special entry cards to grant them access. On testing it out on real-life objects, sample outputs are displayed as shown below for both QR and Barcodes: putText(image,encoded_text,(rect_points,rect_points),cv2. To use the libraries, we will import them using the commands below:Įncoded_text = barcode. We will also need the NumPy library to work with multi-dimensional arrays and matrices. To decode the codes, we will use the pyzbar and zbar libraries. To scan the QR codes, we will use the OpenCV library to read the input images and video streams and display the outputs.
