Hello, I read several pages of how to calibrate a camera but In the end i didn’t found any solution for my project. I want to install several cameras, and each of these cameras should refer to one main world coordinate system.

I searched for a package which could calibrate each of my cameras. But the standard camera calibration package for ROS (with the checkerboard) only determine my intrinsic parameters.

How could I get my extrinsic parameters? Is there another package? Or do I have to describe the coordinates of the camera coordinate-system in the world coordinate-system for each camera?

I am looking for an algorithm which is already implemented. I don’t want to program my own DLT, the Tsai method or other calibration methods by my own.

I appreciate any help Thanks!

PS: I’m using ROS melodic and Basler Kameras

If all your cameras are fixed with respect to each other? Do you have an URDF model of your camera system?

No I don’t have. Imagine several cameras fixed rigid on a vehicle at different positions and I got one world coordinate system of my vehicle
