Title:
仮想視点映像レンダリング装置、方法およびプログラム
Document Type and Number:
Japanese Patent JP7360366
Kind Code:
B2
Abstract:
To enable a composite image being in the middle of rendering in which only a texture of a partial camera is mapped to be viewed when composing a virtual viewpoint image.SOLUTION: A virtual viewpoint image rendering device comprises: a camera image acquisition unit 101 which acquires a camera image; a 3D model acquisition unit 102 which acquires a 3D model created on the basis of the camera image; a virtual viewpoint decision unit 103 which selects a virtual viewpoint; a mapping unit 105 which sequentially maps the texture of each camera image to the 3D model in a camera unit; and a middle image output unit 106 which allows the virtual viewpoint image in the middle of rendering in which only the texture of the partial camera is mapped to be viewed. A camera decision unit 104 decides the number of partial cameras to be less than the number of cameras used in creation of the 3D model. By providing a priority setting unit 104a for setting the priority in each camera instead of the camera decision unit 104, the texture of each camera image may be sequentially mapped in the order based on the priority.SELECTED DRAWING: Figure 1
