Devices and virtual environment generation method, and recording medium storing a virtual environment generation program

摘要

A virtual environment model of an inside of a room is created from a panoramic image thereof by performing the steps of:arranging the panoramic image on a cylindrical body in a virtual space such that information about an angle of view of the relevant panoramic image is reflected;arranging a ceiling plane and a floor plane of said room in said virtual space such that the ceiling plane and floor place are brought into contact with an upper plane and a lower plane, respectively of said cylindrical body;deriving a radius (r) of the cylindrical body from a circumferencial length of said cylindrical body corresponding to a length (L) of said panoramic image and deriving a height (H) of said panoramic image;setting markers (A', B') on the panoramic image, said markers corresponding to vertices (A, B) of posts at respective corners of the room, at said vertices the posts being brought into contact with the ceiling plane and floor plane, respectively on the virtual space;deriving heights (a, b) of said markers on the panoramic image; andderiving a distance (Z) from a virtual view point (O) set in the virtual space to a post (A-B) and a height (w) of said virtual view point (O) from said radius (r) of the cylindrical body, said height (H) of the panoramic image and said heights (a, b) of the markers on the panoramic image.
