Stereo vision, or Stereopsis, is the process in visual perception leading to the perception of depth from the two slightly different projections of an object onto the two eyes. Computer stereo vision mimics this behaviour by having the computer compare multiple images of a scene and determine the ...

Could the X-Y resolution for a stereo camera setup be better than that of either of the cameras alone?

My understanding is that it shouldn't be different than the resolution of a single camera, since the actual X and Y coordinates of a point in space are defined from the point's image up to a scalar ...
