Description
カメラ136(図6乃至図7に図示する如く)の11の定数、Di1(I=1、11)及びカメラ138(図6乃至図7に図示する如く)の11の定数、Di2(I=1、11)は、15の位置におけるX(I)、Y(I)、Z(I)及び2つのカメラの校正写真で測定した15のU1 j、V1 jの座標を知ることで解かれる。
ステップS133で、装置は、所定の範囲外の領域を有するイメージの明るい領域を削除する。従って、大きすぎる、または、小さすぎる領域は、排除される。好適な実施例では、ゴルフボール上のドットは、約0.635cm乃至0.3175cm(1/4インチ乃至1/8インチ)であり、カメラは753×244個の画素を有して、ドットがイメージ中に約105個の画素から成る領域を持つようにされる。しかしながら、クラブヘッド及びその他の物体からのグレアを含んだ正反射によるグレアにより各イメージにおいて追加の明るい領域が現れることがる。従って、領域の画素が105個より大幅に少ないまたは多い場合には、それらはゴルフボールのマーカーであるはずはないとして装置は、斯かる領域を無視することができる。
