平面狭缝图像场

摘要

提出了一种新的基于图像的绘制技术:平面狭缝图像场,即利用狭缝图像的集合来表示和生成场景.在分析平面狭缝图像场性质的基础上,提出了相似狭缝图像概念,从而推导出用有限采样拟合平面狭缝图像场,进而可以实时生成具有高真实感漫游场景的方法.据此提出了采样和拟合的实现.最后,提出了分段狭缝图像映射的方法,大大压缩了所用到的数据量.%A new method for image-based rendering (IBR): rendering using plane slit image field is discussed in this paper. Slit image field is a set of slit images that can represent and generate all scenes in a given region. A concept of analogical slit image is presented. By using it, a method to reconstruct the slit image field as well as work-through scenes from limited samplings is presented. A slit image segment mapping technology to simplify the reconstruct process and reduce data is presented too.
