Abstract:
A measuring device 101 measures the spin of a spherical body. A templater 102 acquires a template image in which the spherical body is captured from a video in which the spherical body is captured or a photographic image in which the spherical body is captured under photographing conditions comparable to the vireo. A clipper 103 extracts a region similar to the template image from the video and acquires multiple clipped images having the center position and size matched. A calculator 104 calculates and arranges in the chronological order similarities/dissimilarities between the clipped images to acquire a matrix. An estimator 105 estimates the spin of the spherical body from the distribution of elements in the matrix of similarities/dissimilarities.
