Marker layout method, mixed reality apparatus, and mixed reality space image generation method
There is disclosed a marker layout method in a mixed reality space, which can reliably detect markers in units of players, even when a plurality of players share a common mixed reality space. According to this invention, markers to be used by only a given player are laid out at positions that cannot be seen from other players. Real objects used in an application that uses a mixed reality space may be used.
1. An information processing method comprising:
obtaining a model of a real object;
obtaining information indicating a movable range of a viewpoint of a given player;
obtaining a layout condition of markers;
computing a range in which the given player can see but the lines of sight of other players are intercepted based on the model of the real object, the information indicating a movable range of a viewpoint of the given player, and the layout condition; and
determining positions at which the markers are to be laid out based on the computed range,
wherein the markers are used for detecting the viewpoint and an orientation of the player.
2. The information processing method according to claim 1 , wherein the layout condition is a layout rule.
3. The information processing method according to claim 1 , wherein the layout condition is the number of the markers.
4. The information processing method according to claim 1 , further comprising:
storing, for each player, the information indicating a movable range of the viewpoint of a player.
5. A computer-readable storage medium containing code for performing an information processing method comprising:
obtaining a model of a real object;
obtaining information indicating a movable range of a viewpoint of a given player;
obtaining a layout condition of markers;
computing a range in which the given player can see but the lines of sight of other players are intercepted based on the model of the real object, the information indicating a movable range of a viewpoint of the given player, and the layout condition; and
determining positions at which the markers are to be laid out based on the computed range,
wherein the markers are used for detecting the viewpoint and an orientation of the player.
6. An information processing apparatus comprising:
an obtaining unit, which obtains a model of a real object, information indicating a movable range of a viewpoint of a given player, and a layout condition of markers;
a processing unit, which computes a range in which the given player can see but the lines of sight of other players are intercepted based on the model of the real object, the information indicating a movable range of a viewpoint of the given player and the layout condition; and
a determination unit, which determines positions at which the markers are to be laid out based on the computed range,
wherein the markers are used for detecting the viewpoint and an orientation of the player.
