Abstract

Abstract System for remotely displaying and sensing information in which an image of information (3) is displayed by a flying-spot scanning device (4) on work area (3). The device (4) contains both a display system and a plurality of non-overlapping sensors receiving images alike in perspective but differing in shadow placement. A computer system (5) including a processor and a storage controls what is displayed and interprets the information received by the sensors. Used without the display function a visualization of work area (3) is obtained that is much more interpretable by a computer than with standard visual parallax for improved robotic visual perception.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 84 words
System for remotely displaying and sensing information using shadow parallax, characterized in that it comprises : . a central processor and a storage; displaying means, for projecting an image representative of information stored in said storage onto a selected area; introduction means for introducing an image of information not stored in said storage onto said area; flying spot scanner means for scanning said area and sensing said information not stored in said storage; and input means for storing said sensed information in said storage
Claim 2
Dependent Claim 84 words
System for remotely displaying and sensing information using shadow parallax, characterized in that it comprises : . a central processor and a storage; displaying means, for projecting an image representative of information stored in said storage onto a selected area; introduction means for introducing an image of information not stored in said storage onto said area; flying spot scanner means for scanning said area and sensing said information not stored in said storage; and input means for storing said sensed information in said storage
Claim 3
Dependent Claim 20 words
System according to Claim 1 wherein said input means stores the sensed information in correlation with the already stored information.
Claim 4
Dependent Claim 46 words
System according to Claim 1 or 2 wherein said flying spot scanner means for sensing said information includes a plurality of non-concentric sensors such that each senses an independent shadow on a common perspective of the introduction means indicative of the movement of said introduction means.
Claim 5
Dependent Claim 17 words
System according to Claim 1, 2 or 3 wherein said displaying means is a cathode ray tube.
Claim 6
Dependent Claim 18 words
System according to Claim 1, 2 or 3 Claim 5 wherein said displaying means is a laser scanner.
Claim 7
Dependent Claim 78 words
Method for detecting the location of an object in a selected area comprising the steps of : a) scanning said selected area point by point; b) sensing said selected area from a plurality of sensors such that each sensor senses an independent shadow on a common perspective of said object in response to said scanning; and c) combining the point by point output of said sensor means to derive a resultant indicative of the location of said object.
Claim 8
Dependent Claim 78 words
Method for detecting the location of an object in a selected area comprising the steps of : a) scanning said selected area point by point; b) sensing said selected area from a plurality of sensors such that each sensor senses an independent shadow on a common perspective of said object in response to said scanning; and c) combining the point by point output of said sensor means to derive a resultant indicative of the location of said object.
