# QR code orientation using OpenCV

![Alt text](https://raw.githubusercontent.com/TemugeB/QR_code_orientation_OpenCV/main/media/Example.gif)

Simple demo that uses OpenCV QR detector and photogrammetry functions to determine the location and orientation of QR code in camera view. Explanation of the code is provided as a blog post here: [link](https://temugeb.github.io/python/computer_vision/2021/06/15/QR-Code_Orientation.html). In this demo, I've included a short video clip as well as the camera calibration parameters. The camera calibration parameters must be known.

**Requirements:**  
Python 3.8  
OpenCV  
Intrinsic camera parameters must be known for your camera.

**Functionality:**  
To see the demo on provided video clip, simply call as:
```
python run_qr.py
```

If you want to use a webcam, call the function with the camera id. For example, webcam registered to 0: 
```
python run_qr.py 0
```

It is recommended that you keep your image resolution low (480p). If you want to use high resolution, resize the image to low resolution right before ```qr.detect()``` call and then rescale back to your full resolution.
