B4J Question Help with corners recognition!

[Beja]

Hello friends,
please see the attached image.. I have a varying rectangle and I want to keep track of it by the device camera and find the coordinates of each corner.
Is there any way to achieve that, here or in B4A?
thanks.

There is no camera library in B4J.
