The depth error for a stereo camera is given by:
As the depth increases the error increases quadratically. I'm wondering if there's a way to model that error and then correct the estimate.
On my camera, I notice that the z value of these points are always over estimated as I move the object further. Is this always the case? Or is the error some sort of gaussian such that it cannot be modeled.
I was wondering if I could just subtract some number from the depth value, based on where the object is to account for the quadratic nature of error and correct it?
