ROTATION STATE ESTIMATION DEVICE, METHOD FOR SAME, AND PROGRAM

WIPO Patent Application WO/2022/162830

A1

In the present invention, the rotation state of an object is estimated by: using, an object estimation image that is an image of the object at time t + w ⋅ u at which the object in an object image, which is an image of the object at a given time t obtained from a time-series input video comprising a plurality of frames, is rotated for w unit times on the basis of a rotation state hypothesis, and an object image at time t + w ⋅ u obtained from the input video, with the absolute value of w being an integer equal to or greater than 2 and u representing unit time; and selecting the rotation state hypothesis and the w for which the likelihood of the object estimation image is high from among a plurality of rotation state hypotheses and a plurality of w having an absolute value equal to or greater than 2.
