The Design And Performance Of Stereoscopic Television Systems

Abstract

Real-time, three-dimensional television systems have already found applications in the guidance of remotely controlled robots and operations carried out under tele-manipulator control. This paper presents an investigation into the performance of a 3-D television system and its dependence on various parameters. It is shown that the region of space which can be displayed in three dimensions without causing undue eyestrain to the observer does not cover the total overlap area of the fields of view of the two cameras. The extent of this region and the minimum detectable depth interval which influences the accuracy of remote handling and inspection tasks are found to be affected by the geometrical and optical parameters of the system.
