项目摘要

This pioneering project is aiming to realize the Integrated 3-D Visual Communication as the next-generation information environment. The results of the project are as follows :1. Proposal of the Integrated 3-D Visual CommunicationSince many works on 3-D image processing have been specialized just for the corresponding 3-D display technologies, we proposed a novel concept of the "Integrated 3-D Visual Communication", in which any kind of 3-D image is represented in the same way. We also pointed out some technological problems which must be solved for the realization of this display-independent representation.2. Representing 3-D ImagesWe investigated the "Ray-Based" method for representing 3-D images, which is neutral for any kind of input system. We also formulated and compared three methods, such as planer, cylindrical and spherical representation.3. Sampling of 3-D ImagesSince a 2-D image can be regarded as a set of light rays, we can see the process of capturing 2-D images as that of sampling light ray data. From this point of view, we proposed a novel method for sampling 3-D spatial data using computer-controlled camera gantry. We also investigated a method for estimating camera parameters from 3-D images.4. Compression of 3-D ImagesWe proposed a multi-dimensional DCT (discrete cosine transform) method for the compression of light ray data. In the proposed method, 3-D images can be decoded in real time. So we can develop some interactive applications by the method.5. Structurization of 3-D ImagesWe proposed some methods for structurizing 3-D images. One is the structure recovery method from 3-D image input, and another is based on the novel concept of structurization of light ray data.6. Displaying 3-D ImagesWe investigated how to display 3-D images in an immersive virtual environment.

这个开创性的项目旨在将综合的3D视觉通信作为下一代信息环境。项目的结果如下：1。综合3-D视觉通信的建议许多关于3-D图像处理的作品已专门针对相应的3D显示技术，我们提出了一个新颖的“综合3-D视觉通信”的概念，其中任何形式的3D图像以相同的方式表示。我们还指出了一些技术问题，这些问题必须用于实现这种与显示无关的表示。2。代表3-D Imageswe调查了代表3-D图像的“基于射线”的方法，该方法对于任何类型的输入系统都是中性的。我们还制定并比较了三种方法，例如刨床，圆柱形和球形表示。3。 3-D成像的采样2-D图像可以视为一组光线，我们可以看到捕获2-D图像的过程，如采样光线数据。从这个角度来看，我们提出了一种使用计算机控制的相机龙门来对3D空间数据进行采样的新方法。我们还研究了一种从3-D图像估算摄像机参数的方法4。 3-D图像的压缩我们提出了一种多维DCT（离散余弦变换）方法，用于压缩光射线数据。在提出的方法中，可以实时解码3-D图像。因此我们可以通过该方法开发一些交互式应用程序5。 3-D图像的结构化我们提出了一些构造3-D图像的方法。一种是从3-D图像输入中的结构恢复方法，另一个是基于光线数据结构化的新颖概念。6。显示3-D Imageswe调查了如何在沉浸式虚拟环境中显示3D图像。
