System for remotely displaying and sensing information using shadow parallax.

摘要

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.
