Abstract

La présente invention concerne un système d'imagerie intégrale à vues multiples utilisant un réseau à double prisme, et fournit une image de reconstruction tridimensionnelle à vues multiples à l'aide d'un système de capture composé d'un réseau à double prisme et d'un réseau de lentilles, le système d'imagerie intégrale à vues multiples comprenant un objet tridimensionnel (400) positionné à gauche d'un réseau de lentilles (200) et un réseau à double prisme (300) positionné entre le réseau de lentilles (200) et l'objet tridimensionnel (400) et ayant deux réseaux de prismes identiques fixés l'un à l'autre, un réseau de prismes étant fixé à l'autre réseau de prismes après une rotation de 180 degrés, de sorte qu'un faisceau de lumière émis à partir de l'objet soit réfracté par le réseau à double prisme (300), et deux prismes étant fixés l'un à l'autre de sorte que le faisceau lumineux émis à partir d'un point de l'objet réalise deux points, et ainsi un objet est visualisé sous la forme de deux images visuelles ayant deux côtés différents et les faisceaux lumineux réfractés traversent le réseau de lentilles (300) et sont captés par une caméra (100), et l'ensemble d'images d'élément formé est une image d'élément pour les deux images visuelles si bien que l'image d'élément générée devient une image d'élément à double prisme (500). Par conséquent, la présente invention peut fournir plus de points de vue qu'un afficheur tridimensionnel classique, présente une facilité d'utilisation de système élevée étant donné qu'un système d'affichage classique est utilisé, et permet de ressentir un sentiment de profondeur supérieur au moyen de multiples points de vue.
