Subpixel resolution in 3D television for teleoperation
Daniel B. Diner, Marika Von Sydow · 2002
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.>
