Abstract:
The image capturing part  201  captures a ball in flight with a camera continuously. The image corresponding part  203  generates a first registered ball image obtained by making a size of a first ball image in a first capturing image captured first correspond to a size of a second ball image in a second capturing image captured second. The 3D model constructing part  204  constructs a 3D model of the first registered ball image obtained by converting a camera coordinate system of the generated first registered ball image into a world coordinate system. The virtual rotating part  205  rotates virtually the constructed 3D model of the first registered ball image by using a rotation parameter estimated in advance and rotation matrix information. The registered image generating part  206  generates a second registered ball image in the camera coordinate system obtained by converting the world coordinate system of a visible surface to see from the camera in the 3D model of the first registered ball image after the rotation into the camera coordinate system. The difference calculating part  207  extracts a second compared ball image corresponding to the second registered ball image in the second ball image, and calculates a difference between the second registered ball image and the second compared ball image. The rotation parameter determining part  208  repeats the virtual rotation of the 3D model, the generation of the second registered ball image and the calculation of the difference, and determines a rotation parameter to minimize the difference as a real rotation parameter.

Claim (Index 5):
The flight parameter measuring apparatus according to  claim 1 , wherein:\n the 3D model constructing processing part calculates the z coordinate (zr 11 ) of x and y coordinates (xr 11 , yr 11 ) of the first registered ball image in the world coordinate system by using the center coordinates c 11  (xrc 11 , yrc 11 ) of the first registered ball image in the world coordinate system, the radius r11 of the first registered ball image, and the following formula (18) below: zr 11 =SQR [r11 sup 2 \u2212{(xr 11 \u2212xrc 11 ) sup 2 +(yr 11 \u2212yrc 11 )sup 2 }] (18), and adopting a positive value in two calculated values from the formula (18), and assigns the positive value of the z coordinate (zr 11 ) to the x and y coordinates (xr 11 , yr 11 ) of the first registered ball image in the world coordinate system.
