VIRTUAL THREE-DIMENSIONAL SPACE GENERATING METHOD, IMAGE SYSTEM, CONTROL METHOD FOR SAME, AND STORAGE MEDIUM READABLE BY COMPUTER DEVICE

摘要

According to the present invention: three-dimensional reference object data which indicates the boundary of a reference object included in an actually photographed image is generated from first data including the actually photographed image, on the basis of the positional relationship between a virtual screen position at which the actually photographed image is shown and a virtual camera position corresponding to a camera position; second data is generated which indicates an object constituting a virtual three-dimensional CG space which is a reproduction of a real space in which the actually photographed image is photographed; and third data for generating a virtual three-dimensional space is generated on the basis of the first data and the second data. The third data is data in which the virtual camera position is defined in the virtual three-dimensional CG space by adjusting the boundary of the reference object in the reference object data to the boundary of the object which corresponds to the reference object in the second data.
