How can I plot axes in image like this ?

Answer 1

[Wayne Xun]

You'll have to use some sort of video tracking in order to determine object positions as they move through the video feed. Using this, keep track of three corners of the board and plot axes by drawing lines between: - each of the two points to a single point - the perpendicular to the plane defined by those three points, through a single point

Use the plot function to plot the lines onto the canvas once you have them
