Opencv exampleHow to run opencv using pixi

The opencv example is located in the pixi repository.

git clone https://github.com/prefix-dev/pixi.git

Move to the example folder

cd pixi/examples/opencv

Run the start command to start the face detection algorithm.

pixi run start

The screen that starts should look like this:

Check out the webcame_capture.py to see how we detect a face.

Next to face recognition, a camera calibration example is also included.

You'll need a checkerboard for this to work. Print this:

Then run

pixi run calibrate

To make a picture for calibration press SPACE Do this approximately 10 times with the chessboard in view of the camera

After that press ESC which will start the calibration.

When the calibration is done, the camera will be used again to find the distance to the checkerboard.
