Requirements and development of depth and spatial orientation sensing

I’m trying to understand from the signal processing perspective how the perception of depth and the ability of spatial orientation is calculated by our brains. One possible explanation seems to be that the brain receives two visual signals, at each interval one signal at each eye. From the differences in the two visual signals (especially from the variation in resolution), the brain can learn to calculate the depth of the merged image signal. This ability however needs to be learned by the brain first, so I would think at least.

• I’d like to ask, at what age do we learn depth and orientational sensing?
• Does the ability to learn this sensing require two receivers of the visual signal? If someone, who was born with only one functional eye, completely blind on the second eye from birth, would this person still be able to develop this sensing, and if yes, would it take this person more time to do this?
