录制讲座录像并加以传播的做法越来越普遍。然而，每日讲座的录制和后处理仍然需要大量人力和财力。我们的目标是开发一个具有成本效益和节省人力的视频处理系统，可以以高清晰度录制讲座并对其进行处理以进行额外的分析和发布。我们的主要想法是，高清录制本身是节省劳动力的。一个固定的高清摄像机可以清晰地记录讲师和整个教室，以便可以在白板和投影仪屏幕上阅读笔记。因此，在记录过程中不需要摄像机操作员。我们成功地实现了一个具有成本效益的系统，无需昂贵的硬件组件来捕获高清视频信号。在这方面的贡献，我们描述了我们的系统，自2010年以来，已记录了约20个讲座，每个学校周的设计和运行结果。
The recording of lecture videos and disseminating them is becoming popular. However, recording and post-processing daily lectures still demands much human effort and financial resources. Our goal is to develop a cost-effective and labor-saving video processing system that can record lectures in high-definition and process them for additional analysis and publishing. Our main idea is that high-definition recording itself is labor-saving. A stationary high-definition camcorder can record a lecturer and an entire classroom clearly so that notes can be read on a whiteboard and projector screen. Therefore, no camera operator is necessary during recording. We succeeded in implementing a cost-effective system without expensive hardware components for capturing a high-definition video signal. In this contribution, we describe the design and operational results of our system, which has recorded about 20 lectures every school week since 2010.
