- Libraries: Install OpenCV (cv2) and Pillow (PIL) libraries using pip (pip install opencv-python pillow).
- Camera Device: A smartphone or a webcam to capture the images.
- Internet Connection: For downloading packages and accessing tutorials.
- Sample Documents: Physical documents to scan and test your code.
Procedure
- Set Up Your Environment: Install Python from the official website and set up a virtual environment.
- Install Required Libraries: Use pip to install OpenCV (pip install opencv-python) and Pillow (pip install Pillow).
- Capture Image: Write a script to capture an image using OpenCV. Use your webcam or smartphone as the input device.
- Preprocess Image: Convert the captured image to grayscale, apply Gaussian Blur, and use edge detection to identify the document’s boundaries.
- Detect and Transform Document: Find contours, approximate the document’s shape, and apply a perspective transform to obtain a top-down view.
- Save the Scanned Image: Save the transformed image using Pillow for high-quality output.
- Run Your Scanner: Test your Python scanner by running the script and capturing documents.
