Subpixel resolution in 3D television for teleoperation

Four trained human subjects were tested for subpixel resolution capabilities, by presenting two identical 3D targets at depths differing in disparity by fractions of a pixel difference. All four observers were able to use the subpixel information when evaluating the relative depth perceived between the two bars. With a viewing distance of 1.3 m, and a stereo camera rig configured to yield a pixel depth resolution of over 5 mm, the observers have demonstrated depth resolution of 1 mm. For high-precision teleoperation, that is, precision on the order of millimeters, these results may extend operator capabilities
