    Sammeln von Billardbildern durch eine Kamera und Übertragen der gesammelten Billardbilder zu einem Server, Empfangen der gesammelten Billardbilder, die durch die Kamera gesendet werden, und Erzeugen einer Bewegungsbahn für jede Billardkugel in Übereinstimmung mit jedem Rahmen der gesammelten Billardbilder durch ein Bahnerzeugungsmodul des Servers, Senden der Bewegungsbahn jeder Billardkugel zu dem Analyse- und Bewertungsmodul, Analysieren und Vergleichen der Bewegungsbahn jeder Billardkugel mit dem Bewertungsstandard, der zu dem Billardtraining-Element gehört, um so ein Trainingsergebnis durch das Analyse- und Bewertungsmodul zu erhalten, und Senden des Trainingsergebnisses zu der Bildschirmanzeigeeinheit zum Anzeigen,
    wobei ein Verfahren für eine erweiterte Realität ferner durch den Server durch Messen eines Abstands zwischen Billardkugeln, Anzeigen eines Bereichs, der durch eine Objektkugel vor einer Spielkugel blockiert ist, Feststellen des Vorhandenseins einer Behinderung, Anzeigen einer Stoßpassage, Zeichnen einer Faltlinienbahn, erneutes Spielen des Stoßes und lokales Zoomen der Bilder durchgeführt wird, um so eine Analyseunterstützungsfunktion für einen Benutzer bereitzustellen.
  10. Billardtraining-Unterstützungsverfahren nach Anspruch 9, dadurch gekennzeichnet, dass
    das Messen eines Abstands zwischen Billardkugeln durch Erhalten tatsächlicher Koordinaten (x1, y1) und (x2, y2) von zwei Billardkugeln und Berechnen des tatsächlichen Abstands zwischen den zwei Billardkugeln nach der Formel: | AB | = x 1 − x 2 2 + y 1 − y 2 2
    Figure imgb0009
     durchgeführt wird, wobei |AB| der Abstand zwischen den zwei Billardkugeln ist;
    das Anzeigen eines Bereichs, der durch eine Objektkugel vor einer Spielkugel blockiert ist, durch das Erhalten von tatsächlichen Koordinaten der Spielkugel und der Objektkugel und das Erhalten von zwei tangential verlaufenden Linien, die sich durch den Kugelmittelpunkt der Spielkugel erstrecken und tangential zu der Objektkugel verlaufen, durchgeführt wird, indem das Gleichungssystem { | x ⋅ k − y + b | k 2 + 1 = r y = kx + b
    Figure imgb0010
     gelöst wird, wobei (x, y) eine physische Koordinate der Spielkugel und der Objektkugel darstellt, r der Durchmesser der Billardkugel ist und dann der Bereich des Vierecks, das durch diese Tangentiallinien mit den Kanten des Billardtischs gebildet wird, als der blockierte Bereich dargestellt wird;
    das Feststellen eines Vorhandenseins einer Behinderung durch Berechnen eines blockierten Bereichs, der durch die blockierende Objektkugel vor der Spielkugel gebildet wird, und das Feststellen, ob die Objektkugel, die gestoßen werden muss, vollständig in dem blockierten Bereich positioniert ist, durchgeführt wird, und woraufhin dann, falls die Objektkugel, die gestoßen werden muss, vollständig in dem blockierten Bereich liegt, festgestellt wird, dass das Erzeugen einer Behinderung erfolgreich ist; wohingegen andernfalls festgestellt wird, dass das Erzeugen einer Behinderung fehlgeschlagen ist;
    das Anzeigen einer Stoßpassage durchgeführt wird, indem tatsächliche Koordinaten der Spielkugel und der Objektkugel erhalten werden und unter Verwendung der Formel y = kx + b überprüft wird, ob die tatsächliche Koordinate der Taschenöffnung auf der Geraden liegt, die durch die Spielkugel und die Objektkugel gebildet wird, wobei (x, y) die Koordinate der Taschenöffnung darstellt und k und b die Steigung und der Schnittpunkt der Geraden sind, die gebildet wird, in dem sie durch die Koordinaten der Spielkugel und der Objektkugel verläuft.
