使用視訊資料庫之視覺化動作比對分析系統

A Visualized Motion Matching And Analysis System Based on Video Database

指導教授 : 張厥煒

摘要


本論文為設計並實作一個視覺化環境為主的運動動作畫面比對分析系統。在以一個多媒體視訊資料庫為基礎的架構下,共建立棒球視訊畫面管理子系統、視訊畫面註記子系統、動作比對子系統,與分析輸出子系統等四個工具。 本系統除提供單、雙畫面同步播放與瀏覽的特殊功能外,並利用時間控制碼選取視訊畫面的特定範圍起終點,在有興趣的視訊畫面適當位置,建立起一個個視訊片段物件,並形成視訊索引。透過此索引與視訊物件內容註記,使用者能夠快速查詢視訊資料庫中畫面內容,並串接成新的視訊影片。此系統能夠有效協助運動動作的教學與分析,球員個人動作調整修正,以及比賽對手資訊的蒐集。運動生物力學對於運動訓練與成效,扮演著重要的角色。因此此運作模式,只要有效的架設與拍攝,便能適用於多種體育項目中,而逐步成為實用的運動學習與分析工具。

In this research, we design and implement a visualized motion matching and analysis system based on video database. In the multimedia database based architecture, the establishment of a video data management subsystem, video annotation subsystem, motion matching subsystem, and result output subsystem. This system not only provides the two-window-display functions of the single frame playback, the fast forward/backward scrollbar playback, the synchronized playback, but also time code used to setup start time and end time in a sequence of video. In the video in place of interest, establish a video clip object, and the formation of a video index. Through this index and video content annotation objects, users can quickly query the database of video content, and a new series of video clips. By using this integrated visual media mechanism, we can help the works of drill coaching, personal skill correction, team strategy evaluation, and competitor scouting. Sports Biomechanics for sports training and effectiveness, plays an important role. So, by camera setting and shooting precisely, this operation model is adaptive to many other sports activities, and will become a practical tool for the sports coaching and analysis.
