ArUco detection x-y axis values are extremely different

edit

Hello. My problem is that I am trying to detect aruco markers. I need coordinates aruco centered so I implemented this part of the code to c++ and checked. Some of the output:

When I check 2 consecutive frames, we can see that even though there are almost no difference in images we get 30 centimeters of difference:

I calibrated well enough and I am sure of it because Z axis is very good. Results for Z axis very fine( in terms of world coordinates) but X and Y axis values are changing very different. Has anyone got the same problem? What could be the problem ?

Any idea is helpful. For the code you can check the permalink above. PS: Numbers in the image-> "Frame number: X Y"
