A rotation estimation device includes an attitude determination section that accepts a plurality of three-dimensional images captured by an image capturing device at a plurality of timings, detects a plane region that is present in common with the plurality of images, and obtains a relative attitude of the image capturing device to the plane region in the image based on the image for each of the plurality of images; and a rotation state estimation section that obtains a rotational state of the image capturing device based on the relative attitude of the image capturing device, the relative attitude being obtained for each of the images.
