Claim One:
1. A moving body recognition apparatus for recognizing a movement of a moving object by positions of features points in an image corresponding to said moving object, comprising: image input means for capturing three images of said moving object at three instances in time at equal time intervals, said three images being observed from a direction perpendicular to an axis of rotation of said object moving on a single plane and said object having a rotation at a constant rate; feature point extraction means for extracting two feature points each in said three images captured by said image input means, said feature point extraction means including space filter means for extracting an outline image from said three images captured by said image input means and edge point extraction means for extracting an edge point from said outline image; feature point position storage means for storing known position data corresponding to said extracted two feature points and for storing said edge point as feature point data; and, shape/movement recognition means for calculating actual positions of said extracted two feature points and a movement of said object from said known position data.
