Hi there , I want to layout aruco markers inside a bus and be able to track the driver's line of sight according to the markers placed.
My goal is to have the markers as smallest as I can (hopefully less than 4cm) and place them between 1m - 1.5m .
This is for experiment to detect the driver's behavior , the USB cam will be mounted on his hat.
I have no idea what is the best camera which will fit this requirement , I currently use microsoft webcam and the quality of detecting markers isn't good , markers need to be big (7cm atleast) to be detected around 70cm distance.
Any recommendations will be welcomed
