A family of single-user autostereoscopic displays with head-tracking capabilities

Abstract

We present prototypes of autostereoscopic displays which allow single users to experience stereoscopic vision without the need for special eye glasses or helmet-mounted displays. The design of the displays is based on lenticular raster plates and includes a number of novel concepts for tracking of raster plates or projection lenses to account for changes of the viewers position in front of the screen. Applications envisioned include 3-D multimedia desktop visualization for medical and biological imaging, design, and architecture, as well as computer games and 3-D virtual reality in general. Concepts and results for both high-resolution flat liquid-crystal panel monitors for PC desktop applications as well as large screen high resolution displays using rear-projection technology are discussed

3DTV rendering from multiple cameras

“…The weight is different for every, of the c = [1,8], original cameras. When the distance approaches zero, the weight gets a great value, but it can never approach infinity, due to the 4 10  factor.…”

“…3DTV Rendering from Multiple Cameras -38 -The RGB values of each of the eight cameras, are represented by a vector V c,. ,(c [1,8] stands for the number of the camera). V c is therefore a 3x1 vector, containing information for the three color components of camera c. The eight V c vectors constitute the dataset of the algorithm.…”

“…Autostereoscopic displays with tracking rely on real time tracking of the viewer position and projecting the left and right parts of a stereoscopic video stream into the corresponding user"s eye. Current trackers and display optics are suited for a single-user 3D video experience only [8].…”

Full Resolution, Low Crosstalk, and Wide Viewing Angle Auto-Stereoscopic Display With a Hybrid Spatial-Temporal Control Using Free-Form Surface Backlight Unit

“…There are attempts to extend the viewing angle to over 15 degrees, but there is no quantitative description to the maximum viewing angle and to the exact crosstalk value at different viewing points. It is generally acknowledged that the crosstalk gets higher as the viewing angle becomes larger as a result of optical aberrations [24]. Although different techniques are utilized to deal with the spherical aberration, the overall crosstalk remains high up to the present [25].…”

Enhancement of calibrated stereo vision depth map estimation for autostereoscopic viewing

“…Over the years several types of 3D display technologies have been developed such as well known red/green stereo glasses-based displays, volumetric displays [1], and autostereoscopic displays [2,3]. The red/green stereo glasses-based displays require inputs from two cameras and hardly any processing, but requires viewers to wear special glasses.…”
