Abstract
The invention relates to an apparatus and a method for measuring rotation quantity of a spherical object. A recording device photographs and records a rotating spherical object from one definite direction as a plurality of stationary circular images at definite intervals. An instrumentation device measures positions of definite two points in each of the recorded stationary circular images. An arithmetic unit calculates rotation quantity of the spherical object on each axis of a three-dimensional coordinate-system on the basis of the positions of the two points in each of the stationary circular images.
