虚拟抠像技术在微课视频制作中的应用研究

Research on application of virtual matting technology in micro-class video production

将虛拟抠像技术应用在微课视频制作中既可以保证教学视频的质量,还可以让微课发展跟上互联网时代发展的步伐。虛拟抠图技术也叫虛拟演播室技术,其将摄像机拍摄的图像和计算机设计的三维虚拟背景空间进行有效融合,从而形成一种新的视频图像。

Applying virtual matting technology to the production of micro course videos can not only ensure the quality of teaching videos,but also keep the development of micro courses up with the pace of the Internet era.Virtual matting technology,also known as virtual studio technology,effectively integrates the images captured by the camera with the three-dimensional virtual background space designed by the computer to form a new video image.
