From observation, there is a natural bias where the lower part of the image is always closed to the camera. As we discussed above, we derived the equation for depth with the following assumptions. The camera can also find the distance of the subject. The camera sends it's video feed of this distorted dot pattern into the depth sensor's processor, and the processor works out depth from the displacement of the dots.
