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.

这项研究针对的是创建“基于射线的图像工程”。在基于射线的图像工程中，3D空间信息由光线射线表示。视觉系统的捕获，处理和显示等所有组件均不视为基于像素的，而是基于射线。为了显示，我们已经开发了3D显示屏，并成功地从射线空间数据创建了3D图像。现在，我们主要关注用于射线捕获和处理的技术。对于捕获，我们为多相机阵列开发了一种准确且高效的定位方法。我们还开发了一种方法来通过校正由多相机阵列缩小的图像来构建射线空间。我们开发了场景分离和合成的方法，以及通过信号处理射线空间上的信号处理来模拟光学现象的特殊效果的产生。射线空间数据压缩是通信所必需的，是使用多视图图像之间的相似性开发的。此外，我们开发了射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。相互转换表明，射线空间可以描述全息图的等效信息。这项成就为射线空间提供了物理意义，并且证明射线空间是3D空间信息的普遍表示，而不是捕获和显示方法。
