1. A moving body recognition apparatus for recognizing a movement of a moving object by positions of feature points in an image corresponding to said moving object, comprising:

  • image input means for capturing images of said moving object;

    feature point extraction means for extracting feature points in said images captured by said image input means;

    feature point position storage means for storing known position data corresponding to said extracted feature points; and

    shape/movement recognition means for calculating actual positions of said extracted feature points and a movement of said object from said known position data of three of said extracted feature points forming a right angle of said object each in said images captured at any two instances in time from a direction perpendicular to an axis of rotation of said object moving on a single plane and said object having a rotation, two positions at said two instances of any one of said three feature points being on a plane parallel to said direction perpendicular to said axis of rotation.
