The video shows a program made using OpenCV with python.
The program detects the position of the chessboard and places and image in the center. The perspective of the image will vary according to the chessboard.
The program allows to change the level of zoom, to change between images and to increase or decrease the threshold used to isolate images with black background.
You can see the options selected (zoom, change image...) in the log tab at the bottom right corner.
You can download the code and the sample images from the link below:
