Arucos detection and Cameras

edit

So I'm working with arucos to try to get the pose of some robots. Using pkg: http://wiki.ros.org/ar_sys

I'm having problems with detecting the arucos at bigger ranges. Using a camera um my laptop I can catch an Aruco at almost 2 meters, aruco size was ~12cm. But in Ros I can only detect the arucos at 0.7 meters max using arucos with size ~6cm.

Is the only way to get bigger ranges in aruco detection, to make the arucos bigger in size, or can I change the camera In some way?

Like having 2 cameras one zoomed for bigger ranges and another not zoomed for close range detection?

Anyone has experience in this? Thx so much.
