IMPROVED THREE-DIMENSIONAL STEREOSCOPIC RENDERING OF VIRTUAL OBJECTS FOR A MOVING OBSERVER

摘要

A system is for three-dimensional stereoscopic rendering of virtual objects in a scenario by a display screen (S) with respect to which an observer (O) can move. The system overcomes the problems of incorrect perception of three-dimensionality which are present in prior art stereoscopic rendering systems. The system includes a device (20) adapted to detect the coordinates of the respective observation position (OL,R) in a predetermined reference system related to the screen (S), by computing (estimating) the positions of the observer's eyes, and includes a processing unit (10) adapted to generate, for each object point (T), a pair of corresponding image points (tiL,tiR) on the screen (S), which are selectively visible to the observer (O) and are related to the detected current observation position (OiL,R).

1. System for three-dimensional stereoscopic rendering of virtual objects without distortion in a virtual or augmented reality scenario by a display screen with respect to which an observer can move and/or change his/her position and/or the orientation of his/her head and consequently a position of his/her eyes, including processing means adapted for generating, for each virtual object point defined in a three-dimensional coordinate system, a pair of corresponding image points on said screen which are selectively visible to the observer, comprising:
means for tracking an observer, adapted to detect the coordinates of a respective observation position in a predetermined reference system related to the screen; wherein said processing means are arranged to generate, for each virtual object point defined in a three-dimensional coordinate system, a pair of corresponding image points on said screen as a function of the position of the eyes of the observer in a detected current observation position.
