Abstract
現在野球映像における投球動作の分析は,専門家の感性や経験によって手作業で行われることが多く,多くの時間を要する問題がある.そこで本稿では,特に戦略上有効な各投手特有のクセを発見する手法を提案する.提案手法では,クセの最も発生しやすいグローブの向きに注目し,パーティクルフィルタによってグローブを追跡し,SIFTによってグローブの勾配方向を計算しクセの分析を行う.評価実験として,クセを持つ投手に対し提案手法を適用し,クセが発見できていることを確認した.
At present, analysis of pitching motion from baseball videos is time-consuming since it is often performed manually by experts with professional knowledge and expertise. In this article, we propose a method to detect the habit of a pitcher effectively from a strategical perspective. We focus on the direction of a glove that is most likely to be detected as a habit. We track the glove using the particle filter and analyze the gradient directions of the glove using the SIFT. We applied the proposed method to a certain pitcher who is known for his habit and proved the effectiveness of our method.
