The Three-Dimensional World
3-D vision
Humans are able to employ 3-D vision with consummate ease, and according to conventional wisdom, binocular vision is the key to this success. The truth is more complex than this, and this chapter demonstrates why.
Look out for:
• what can be achieved using binocular vision.
• how the shading of surfaces can be used in place of binocular vision to achieve similar ends.
• how these basic methods provide dimensional information for 3-D scenes but do not immediately lead to object recognition.
• how the process of 3-D object recognition can be tackled by studies of 3-D geometry.
Note that this is an introductory chapter on 3-D vision, designed to give the flavor of the subject and to show its origins ...
