| dc.description.abstract | We describe a scheme for reduction of depolarization artefacts in passive stereo-projection systems. These problems appear due to non-perfectness of stereo-projection equipment: depolarization of the light due to reflection from the screen or due to the passage through the screen, non-ideality of polarizing filters, mixing of left- and right-eye images in a change of relative orientation of the filters, which together produce a strong crosstalk effect, resulting to difficulting stereo-perception. The artefacts are eliminated by software methods, using linear filtering of the image before its projection to the screen. We have implemented this algorithm in VE system Avango 1 by means of texture mappings. All necessary operations are performed by the graphics board, thus providing the real-time rendering rate. The described method considerably improves stability of stereo-perception, making high-quality performances of virtual environment possible on affordable equipment. | en_US |
