![]() ![]() The system’s use of a ‘spatially imaged iris plane screen’ and ‘linear blending technology’ enables it to have fewer image sources and projectors than existing multi-view projection. GOODSON, STEVEN RITTER, and RANDY THORPE DePauw University, Greencastle, Indiana 46135 This experiment was designed to study the influence of motion parallax on depth and move ment perception. The resulting parallax, which is an epipolar field, is estimated using an adaptive windowing technique and used to obtain the refined depth map. This paper describes a glassless 3D screen system we propose that is capable of natural stereoscopic viewing with motion parallax in a wide viewing area. Motion parallax in depth and movement perception FELIX E. The reference depth map is used to estimate the camera motion and the motion of the 3D points on the reference surface is compensated. The term parallax refers to a change in position. A Motion Parallax Rendering Approach to Real-time Stereoscopic Visualization for Aircraft Virtual Assembly As a cue to depth perception, motion parallax can improve stereoscopic visualization to a level more like human natural vision. ![]() A coarse and potentially incomplete depth map of the scene obtained from a digital elevation map (DEM) is used as a reference surface which is refined and updated using this approach. For the egocentric orientation of observers moving with respect to a plane (e.g., pilots and automobile drivers), the movement parallax field provides the main cue. Motion parallax is a monocular depth cue arising from the relative velocities of objects moving across the retinae of a moving person. This generalizes the plane-parallax recovery methods to surface-parallax using arbitrary surfaces. In this thesis we have studied detection of 3D structures having a forward camera movement which has strong influence of translation along the optical axis. We present an approach to update and refine coarse 3D models of urban environments from a sequence of intensity images using surface parallax. Rather, the direction of image motion relative to observer motion is crucial to specifying depth-sign (Fig. ![]() A plane surface and an eye (the terrestrial situation.
