Abstract

Dans les présents films et télévision 3D, des premières doubles caméras 2D sont spécialement utilisées pour photographier des angles afin de produire une vidéo 3D, et des lunettes correspondant à la technologie de photographie sont utilisées pour décomposer les deux vidéos en images stéréoscopiques 3D pendant la lecture. Les caractéristiques techniques du procédé de la présente invention sont les suivantes : au moyen d'une analyse physique et optique, il est déterminé qu'il existe des éléments d'informations stéréoscopiques 3D dans une vidéo 2D, et il est trouvé que la raison pour laquelle aucun effet stéréoscopique n'est produit lorsqu'une personne regarde une vidéo 2D à l'aide des deux yeux est que l'effet d'«interférence» entre les deux yeux provoque l'échec de l'effet stéréoscopique ; à cet égard, une théorie de décomposition et de conversion d'une vidéo 2D en une vidéo 3D et un procédé de production sont inventés et un dispositif de lunettes est produit par le procédé de production. Selon la présente invention, la présente technologie de film 3D et de télévision est scientifiquement et théoriquement interprétée, et le concept de technologie 3D existant est élevé au niveau d'une théorie de technologie 3D, rendant l'effet de l'invention théorique plus scientifique ; ainsi, la photographie d'un film 3D est transférée de la photographique de la scène à la lecture d'une image vidéo 2D ; lorsque l'on utilise des lunettes 3D pour regarder une image 2D, les lunettes «photographient» une vidéo 2D, et au moyen de la différence de vision optique dans les lunettes et de la fonction de décomposition spatio-temporelle 4D de vidéo 2D de l'optique électronique, on voit une image vidéo 3D restaurée. La présente invention couvre un procédé de production théorique de l'invention, et est une invention d'un procédé de production de lunettes 3D. La technologie de l'invention peut rendre des sources de film 2D et de journaux de télévision, littéraires, artistiques, et sportifs en vidéos 3D, ce qui permet d'obtenir un effet visuel stéréoscopique 3D complet lors de la visualisation de films 2D ordinaires et de télévision par port de lunettes.
