# Error Projection Points ArUco Marks

Hello,

I am developed an application for calibrate 3 cameras, i'm using an Aruco board 3D. When i try to project points from 3D to 2D and then draw this, the ids markers is drawn randomly. I don't understand why this happens and is harder draw this markers exactly. I attach the image with the result

Below you can see the output of my calibration
