Excerpt from Some Remarks on Robot Vision

Visual information most useful if it is given as 3-d visual data, i.e. If true 3-d coordinates are immediately calculated for all points observed. We note that devices which provide such 3-d data, usually based on laser-beam scanning or on use of specially 'structured light' are commercially available already; see e. G. [t83] The crucial advantage of 3-d vision is that it allows images to be acquired by arbitrarily many eyes. Whereas to take ordinary (2-d) images acquired by several eyes and combine them is not easy, multiple 3-d images of a single scene combine in a trivial way, since they all refer to surfaces in a common geometric space. This makes it possible to use arbitrarily many eyes, some fixed, others mounted on moving parts of the robot system. (eyes need to be mounted on the robot itself if either the robot can roam freely, or to ensure that the space near moving porn'ons of the robot is not obscured, either by an intervening object or by parts of the robot itself. This second purpose may require specialized eyes of appropriate form and position.) Note that an 'all seeing' eye system of this sophis tication subsumes a quite satisfactory proximity sensor, and makes other forms of proximity sensors superfluous.
