| accommodation |
focussing of an observed point |
| angulation / convergence |
resulting angle spanned between the optical axes of the two cameras |
| autostereoscopy |
seeing a picture three dimensional without additional utilities (glasses) |
| binocular |
with both eyes |
| convergence |
to pivot both optical axes to an observed object |
| depth cues |
information about the depth of a scene; there are monocular depth cues like perspective and binocular depth cues like stereopsis |
| deviation |
parallactic displacement of corresponding points on two 3D-exposures (left and right image) |
| disparity |
distance of two corresponding points on the retina |
| far point |
the farthest point from the nodal point of the camera |
| Fovea Centralis |
area of the sharpest vision on the retina |
| Horopter |
set of points for which the light falls on corresponding areas in the two retinas |
| interaxial (distance) / stereo base |
distance of the center-points of the two camera lenses |
| interocular distance |
distance of the center-points of the eyes |
| monocular |
with one eye |
| motion parallax |
change of angular position of two stationary points relative to each other as seen by an observer, caused by the motion of an observer |
| near point |
the nearest point from the nodal point of the camera |
| nodal point |
point about which a lens is rotated where close and distant subjects focused on the film plane maintain their relative positions to one another |
| Panum's fusional area |
region of binocular single vision |
| parallax |
change of angular position of two stationary points relative to each other as seen by an observer. If there is no parallax between two objects then they occupy the same position. |
| pseudoscopy |
inversion of the spatial impression |
| plane of screen |
image plane mapped directly on the surface of the screen |
| screen parallax |
distance of two corresponding points on the screen surface |
| stereopsis |
ability to make fine depth discriminations from parallax provided by the two eye's different positions on the head |
