快速移動物體的定位及視覺化: 棒球打擊模擬

Abstract

虛擬實境的整合環境中，營造身歷其境的相關研究已有不錯的成 果．因此在本篇論文裡，我們整合既有的虛擬實境技術，建構一個棒球打 擊的訓練環境．利用電腦合成一個棒球場及一個虛擬的棒球，透過頭戴顯 示器呈現在使用者眼前，然後再利用影像處理與圖形識別的技術偵測使用 者揮棒的位置，做碰撞偵測，以決定是否擊中球． As to an integrated environment of the virtual reality, the research in creating an immsersive environment has been progressed. To apply the visualization and positioning for rapid moving objects in avirtual environment, we can comprehensively provide a well trainingenvironment for perceiving rapid moving objects. In this thesis, we integrate the existed results to construct avirtual environment for baseball striking training. We use the computer to make up a basebal park and a virtual baseball, the show these imageson HMD (Head-Mounted Display). The use could play the baseball according his vision. The we use video capture images to detect the user's playingtime and position. We also make collision detection from those captured images.
