近年來隨著電腦的運算能力越來越強，以及人機互動技術的不斷進步，使得支援3D動作的人機互動不再遙不可及。本篇論文提出了一套即時的動作追蹤系統，讓使用者在空手的情況下，即可與虛擬實境場景互動。本系統只要架設兩台常見的CCD攝影機，透過影像處理技術追蹤使用者的動作，再利用立體視覺的原理，本系統更可以進一步的計算出動作物件之三維座標，並且進行三維動作的辨識，最後經由動作分析即可與虛擬實境場景互動。由實驗結果證明，本系統可以使用常見的低成本設備，達成了直覺化的人機互動功能。 Based on the development of computer’s capability and the technology of human-computer interactions, the 3D human-computer interaction is no longer a dream. In this paper, we propose a real-time 3D motion tracking and interaction system which makes the user could interact with virtual reality systems without any equipment in hand. The proposed system adopts only two general CCD cameras to capture user’s 3D motion information based on the theory of stereo-vision, according to our interaction mechanism, user can interact with the virtual reality intuitively. The experiment shows that our low cost system performs real-time 3D human-computer interaction with virtual reality satisfied.
