Handling the click process

Hello sir,

I am interested in your work and want to try your code.
I don't know why I can't calibrate it.
Would you help me to check?

The following is my video.

Hi @yanlong658, in your video, it doesn't look like you've understood the correct way to click. For each line, you should click 4 times to create a quadrilateral that will enclose the points of a segment. And remember that after each click, you should press a key (like a for example). Here's an image of what a quadrilateral should look like.

I hope this helps you!
