Eye-in hand calibration

Hi everyone, I am doing a project to grasp objects in a shelf with an UR10 by using an Intel RealSense 435i to guide the robot. I am using python and OpenCV. At this point I understand the formula to obtain the eye-in-hand calibration matrix which is:

but I don’t understand on how to get those matrices.
Also, I dont know what to do with the resulting eye-in-hand calibration matrix.
Could someone help me on this?
