摘要

我们探索投影图像与实体书的整合,作为多媒体数据的有形界面。使用相机和投影仪对,提出了一种跟踪框架,其中平面页面的3D位置在用户来回翻转时被监控,并且数据以交互速率正确地扭曲和投影到每个页面上。书的书页是空白的,所以传统的追踪显示表面物理特征的方法不适用。相反,在每一帧中,从相机和投影仪图像中独立提取特征点,并进行匹配,以恢复运动页面的几何形状。这本书可以加载多媒体内容,包括图像、视频和体积数据集(在这种情况下,可以从书中删除一页,用于浏览虚拟3D卷)。

The universal media book: tracking and augmenting moving surfaces with projected information
We explore the integration of projected imagery with a physical book that acts as a tangible interface to multimedia data. Using a camera and projector pair, a tracking framework is presented wherein the 3D position of planar pages are monitored as they are turned back and forth by a user, and data is correctly warped and projected onto each page at interactive rates. The book pages are blank, so traditional approaches to tracking physical features on the display surface do not apply. Instead, in each frame, feature points are independently extracted from the camera and projector images, and matched in order to recover the geometry of the pages in motion. The book can be loaded with multimedia content, including images, videos, and volumetric datasets (in which case a page can be removed from the book and used to navigate through a virtual 3D volume).
