Abstract
(EN)
This video display system (1) comprises: a marker (3); a first polarization filter (4); a video display device (2); and a variation calculation unit (25). The video display device (2) includes a camera (23), a display unit (22), and a second polarization filter (24). The first polarization filter (4) is disposed corresponding to the marker (3). The camera (23) captures an image of the marker (3). The second polarization filter (24) is disposed corresponding to the display unit (22), and has a polarization characteristic that is opposite to that of the first polarization filter (4). The variation calculation unit (25) calculates a variation between a first image (MRF) acquired by the camera (23) in a first attitude and a second image (MCP) acquired in a second attitude, and calculates an attitude variation of the video display device 2 on the basis of the variation.

L'invention concerne un système d'affichage vidéo (1) comprenant : un marqueur (3); un premier filtre de polarisation (4); un dispositif d'affichage vidéo (2); et une unité de calcul de variation (25). Le dispositif d'affichage vidéo (2) comprend une caméra (23), une unité d'affichage (22) et un second filtre de polarisation (24). Le premier filtre de polarisation (4) est disposé en correspondance avec le marqueur (3). La caméra (23) capture une image du marqueur (3). Le second filtre de polarisation (24) est disposé en correspondance avec l'unité d'affichage (22) et présente une caractéristique de polarisation opposée à celle du premier filtre de polarisation (4). L'unité de calcul de variation (25) calcule une variation entre une première image (MRF) acquise par la caméra (23) dans une première orientation et une seconde image (MCP) acquise dans une seconde orientation, et calcule une variation d'orientation du dispositif d'affichage vidéo (2) en fonction de la variation.
