本論文為設計並實作一個以視覺化環境為主的整合式多媒體棒球比賽資訊系統。在以一個多媒體視訊資料庫為基礎的架構下，共建立了比賽記錄與攻守資料查詢子系統、棒球視訊畫面資料庫子系統、動態分析評估子系統三個工具。其中，比賽記錄與攻守資料查詢子系統使用視窗圖形介面與時空資料庫，在專業棒球記錄標準下，將棒球比賽中複雜的空間與時間性(Spatio-temporal)資料，有效的轉換成數位視訊內容與文數字資料記錄，完整儲存於電腦系統中，便於提供比賽現場的即時性資訊研判，與日後長期資料累積分析。棒球視訊畫面資料庫子系統使用視訊資料庫機制，定義視訊物件，建立以時間控制碼為主的多種資料庫檢索，提供視訊資料瀏覽與查詢功能。動態分析評估子系統建立友善的同步播放視訊畫面功能與量測工具，有效的協助動作過程剖析。此一整合式系統搭配各種影音資料與視覺技術，將科技與運動結合，以提升運動研究之進行。

In this paper, we design and implement an integrated baseball information system based on visual environment. We use multimedia video database as our kernel architecture, and construct three useful tools: (1) Recording and Query Subsystem, (2) Baseball Video Database Subsystem, (3) Motion Analysis Evaluation Subsystem. The Recording and Query Subsystem is designed according to the professional baseball score recording standard, and developed by spatio-temporal database and graphics user interface. It transfers the complicate baseball spatial and temporal competition situation into digital video contents and alpha-numerical data format. The Baseball Video Database Subsystem uses the mechanism of video database, and constructs various content indices by video object attributes and video time codes, and also supports tools for video browsing and query searching. The Motion Analysis Evaluation Subsystem provides effective and user friendly playback and measurement tools for motion analysis. With the help of various media types and visual technologies, this integrated system will substantially improve the research capability of sports science.
