中文摘要 | 史前人類將他們在狩獵時所看到的動物或景像刻畫在洞壁上面,讓別人知道他所想要捉拿的動物及所看的景像。隨後人們開始運用雕刻刀在石頭上刻畫出許多生動的雕像、運用畫筆在紙張上描繪出許多生動的人物動作畫像、運用照像機來留住運動時精采的片段、運用攝影機來記錄比賽中的點點滴滴。這些就是動作捕捉,即運用各式的器具,來捕捉各種活動中精采的一刻。電腦科技的發達,運用電腦作動作的捕捉,已成為的一種可行且快速的極佳方式。我們稱它為「電腦化的動作捕捉系統」。它在分頻上有:機械式、電磁式、光學式及影帶式。而在選用時應先考量環境與運動項目,如此才能發揮其真正的功用。在體育運動上,它可應用的層面相當的廣泛。在研究上,用來分析動作頻率、規則性、高度、長度。在訓練上,用來縮短訓練的過程、減少傷害。在教學上,再與虛擬實境相結合後,將使教學的內容與品質更加的完整。另在休閒上,它可以真實地紀錄動作,更可以節省時間與成本。電腦化的動作捕捉系統,所擷取到是的肢體在空間中的座標,只是資料,而非資訊。唯有搭配適當的內容,如運用它來建構人體結構或用來作力學上的分析,將資料轉化為資訊,才能夠找出及發揮動作捕捉系統的功能。才能使運動、訓練、教學及研究上更加的安全、科學、經濟與實用。 |
英文摘要 | In ancient history, our ancestors painted animals and scenes saw while hunting to wall of caves to make others to know and to believe what he saw. After that, human beings started to use knifes to engrave stones to statues, to paint vivid action images on papers, to use camera to keep the most important images in exercise, to capture the entire things in competitions. All above discussed are motion captures. It meant to be that we can use different tools to capture the most magnificent moments. Later, with the develop of computer, it becomes more feasible and more fast to use computers to capture the movements. We call it the "computerized motion capture systems". It can divided it into four divisions. It includes the mechanical system, the magnetic system, the optical system and the video-style system. We should think more about the motion environment and character of sports before choosing motion capture system you want to buy. We can utilize it in many areas in physical education and sports. In researching, we can use it to analyze the motion frequency, regularity, height or length. In training, we can use it to reduce the consume of time o ft raining and to prevent the accidental injuries. In teaching, we can combine the visual reality to make the teaching content and quality more complete. In leisure, it can not only completely capture the motion, but also can reduce the time and cost in leisure kind activities. Computerized motion capture system can capture the axes of different parts of body in space. It's just the data, not the information. If we can utilize it like using it to rebuild the skeleton of body or using it to analyze the biomechanics, by transforming data to information, then we can find out and optimize the function of motion capture systems. It will make the sporting, training, teaching and researching more safety, logic, economic and practical. |
