A technique that enables, even if a video image corresponding to one period is not obtained, estimating a rotational state of an object is provided. The rotational state estimation device includes: an object image generation unitthat generates object images, each of the object images being an image of an object, from an input video image; and a rotational state estimation unitthat estimates a rotational state of the object by selecting, from among a plurality of hypotheses of the rotational state, a hypothesis of the rotational state, a likelihood of an image of the object resulting from the object in the object image at a certain time being rotated for tunit time based on the hypothesis of the rotational state being high, using the object image at a time t and the object image at a time t+twhere tis a predetermined integer of no less than 1.

Rotation state estimation device, method and program

A technique for interpolating positional information of a target in an image of a frame in which positional information of the target has not been acquired. An information interpolation device includes: a target information acquisition unitacquiring target information that is information related to a target in an image of each frame composing an input video; an indicator determination unitdetermining, based on the target information, an indicator indicating validity as a starting frame for each frame, the starting frame starting predetermined image processing on a target; a starting frame determination unitdetermining a starting frame based on the determined indicator; and a target information interpolation unitinterpolating, when a frame in which positional information of a target is not included in target information exists among frames within a predetermined number from the determined starting frame, positional information of the target of the frame that does not include the positional information of the target by using positional information of the target included in target information of a frame other than the frame that does not include the positional information of the target.

Preliminary experience of a match at a player's perspective is enabled. A virtual environment material storagehas stored therein virtual environment materials for reproducing a dynamic object and a static object on a virtual environment. A dynamic object sensing unitchronologically measures a position and a posture of the dynamic object in a real environment and generates position and posture information composed of one movement action. A presentation sequence acquisition unitobtains a presentation sequence including position and posture information of a plurality of different kinds of dynamic objects. A virtual environment construction unitsynthesizes a virtual environment material of the dynamic object and a virtual environment material of the static object based on the presentation sequence to construct the virtual environment.
