A system and method for measuring the potential eyestrain felt by audiences while watching a 3D presentation, e.g., a stereoscopic motion picture, are provided. The eyestrain measurement system and method of the present disclosure is based on the measurement of disparity (or depth) and disparity transition of stereoscopic images of the 3D presentation. The system and method of the present disclosure provide for acquiring a first image and a second image from a first segment (202), estimating disparity of at least one point in the first image with at least one corresponding point in the second image (204), estimating disparity transition of a sequence of first and second images (206), and determining potential eyestrain felt while viewing the 3D presentation based on the disparity and the disparity transition of the sequence of the first and second images (208).

L'invention concerne un système et un procédé destinés à mesurer la fatigue oculaire potentielle ressentie par un public visionnant une présentation 3D, par ex. un film stéréoscopique. Le système et le procédé de mesure de la fatigue oculaire selon la présente invention sont basés sur la mesure de la disparité (ou du relief) et de la transition de disparité des images stéréoscopiques de la présentation 3D. Le système et le procédé selon la présente invention permettent dacquérir une première image et une deuxième image issues dun premier segment (202), destimer la disparité dau moins un point de la première image avec au moins un point correspondant de la deuxième image (204), destimer la transition de disparité dune suite de premières et de deuxièmes images (206), et de déterminer la fatigue oculaire potentielle ressentie en visionnant la présentation 3D sur la base de la disparité et de la transition de disparité de la suite de premières et de deuxièmes images (208).
