摘要： A virtual viewpoint image generation method for generating a virtual viewpoint image that is an image of an object viewed from a virtual viewpoint based on plural images of the object taken by plural cameras. Projection planes having a multi-layered structure are set on the images of the object, corresponding to a projection point of a projection plane. Color information of each projection point is determined based on color information of corresponding points, for each of the projection points overlapping when viewed from a reference viewpoint in a space. A degree of probability that the object exists at a distance corresponding to a position of the projection point is determined based on a degree of correlation of the corresponding points.

摘要： According to the method and apparatus, light beams directed toward virtual visual points are detected from among light beams emitted from or reflected on the surface of an object. The detection is effected by an image pickup device in a plurality of positions lying on a virtual closed surface with which the object is enclosed. The detected light beams are converted into image pickup signals, which are delivered to a display device adapted to display an image toward a visual point of an observer standing or sitting in a place different from a place where any of the virtual visual points is disposed. The image is displayed in such a manner as if light beams were emitted toward the visual point of the observer from various points on the surface of a virtual object disposed in a virtual position corresponding to the relative positions of the real object and any of the virtual visual points. The invention is particularly adapted for enabling persons present in different localities to feel as if they met together in a room.
摘要翻译：根据该方法和装置，从从物体的表面发射或反射的光束中检测到朝向虚拟视点的光束。检测由位于虚拟封闭表面上的多个位置的图像拾取装置实现，物体被封闭在该虚拟封闭表面上。检测到的光束被转换为图像拾取信号，该图像拾取信号被传送到适于向位于不同于任何虚拟视点的位置的位置的观察者的视点显示图像的显示装置。该图像以如下方式显示，即如同从布置在虚拟位置的虚拟对象的表面上的各个点向观察者的视点发射光束，该虚拟对象对应于实际对象的相对位置和虚拟对象中的任何虚拟对象视觉点。本发明特别适用于使存在于不同地方的人感觉到在房间里一起见面。
