# Is it possible to make stereo RIG camera setup with one IR and one RGB Camera, i tried this but my disparity map is very poor, is this because i am using different cameras?

probably not possible because the pictures look different.
do you want to change the disparity calculation algorithm so that it can find patches that _don’t_ look similar?
