Abstract
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.
