项目摘要

This research targets the creation of "ray-based image engineering". In the ray-based image engineering, 3D spatial information is represented by light rays. All components such as capturing, processing, and display of the visual system are treated not as pixel-based but ray-based. For displaying, we have developed 3D display and succeeded to create 3D images from ray-space data already. Now, we focus mainly on technologies for ray capturing and processing.For capturing, we developed an accurate, and efficient positioning method for a multi camera array. And we also developed a method to construct ray-space by correcting images capured by multi camera array.We developed methods for scene separation and synthesis, and the generation of special effect simulating optical phenomenon by signal processing on ray-space. Ray-space data compression, which is necessary for communication, was developed using similarities between multi-views images. Moreover, we developed mutual conversion between ray-space and hologram. The hologram based on physical phenomenon of light waves and their propagation is considered as an ultimate 3D image displaying method. The mutual conversion shows that ray-space can describe equivalent information for the hologram. This achievement gives physical meaning to ray-space as well as it proves that ray-space is a universal representation of 3D spatial information independent of capturing and displaying methods.

本研究的目标是创建“基于射线的图像工程”。在基于光线的图像工程中，三维空间信息是由光线表示的。视觉系统的所有组件，如捕获、处理和显示，都不是基于像素的，而是基于光线的。对于显示，我们已经开发了3D显示，并成功地从光线空间数据创建3D图像。本文主要研究了光线的采集和处理技术，提出了一种多摄像机阵列精确、高效的定位方法。提出了一种基于多摄像机阵列图像校正的光线空间构造方法，并在光线空间上进行信号处理，实现了场景的分离与合成，以及模拟光学现象的特效生成。光线空间数据压缩，这是必要的通信，开发使用多视图图像之间的相似性。此外，我们开发了光线空间和全息图之间的相互转换。基于光波及其传播的物理现象的全息图被认为是最终的3D图像显示方法。这种相互转换表明，光线空间可以描述全息图的等效信息。这一成果赋予了光线空间以物理意义，同时也证明了光线空间是一种与获取和显示方法无关的三维空间信息的通用表示。
