Abstract

In this paper, a problem of interactive stereoscopic display is considered. To provide a stereo image pair with correct viewing angle, a stereoscopic system must be able to identify a viewer spatial location. A fast and low-cost viewer location estimation method using a single video camera is described in this paper. The method tracks a viewer's standing position by estimating his/her leg end-point on the floor. The so-obtained position is then transformed to a 3D coordinate by using a planar homographic projection. Because the estimated viewer position is noisy, a smoothing and semi-interactive updating algorithm is developed to reduce a flicker caused by the imprecise estimate. © 2005 IEEE.
