使用C ++在OpenCV中单击鼠标功能

Question

I am relatively new to OpenCV and I am trying to work on virtual mouse. I figured out how to detect different colors and filter them out. I couldn't find how to make mouse click when specific color is detected. Here my sample code:

if (b == 1){
        if (x >= 0 && y >= 0 && PosX >= 0 && PosY >= 0)

        //Here is the function to left clicking the mouse

    }

I figured out how to move the mouse. I used SetCursorPos(x,y) . I would appreciate any help. Thank you in advance!

Answer 1

The mouse click event comes with the x,y of the mouse position. Use these coordinates for accessing the image.
Take a look at SetMouseCallback() .
Here's an example of how to use it.
