演講錄製(Automated Lecture Recording)在線上學習與遠距教學中,扮演非常重要的角色.以往多由攝影師或靜態的相機予以記錄. 本篇文章將發展出自動化的錄製演講系統,利用PTZ攝影機來模擬真實攝影師所錄製的方式.本系統主要分為前處理、取得演講資訊以及攝影機動作,在演講過程中根據不同事件的發生,對PTZ攝影機下達合適的動作,來拍攝出效果較佳的影像。 Lecture recording plays an important role in online learning and distance education. Most of they are recorded by a cameraman or a static camera. In this paper, we propose an automatic lecture recording system. A Pan-Tilt-Zoom (PTZ) camera is shooting as
