摘要： The images of an object taken at a plurality of viewpoint positions are input together with information indicating the plurality of viewpoint positions, and the viewpoint position of an observer is detected. One of the input images is selected on the basis of the detected viewpoint position of the observer, and the scan line of the image is determined in accordance with the viewpoint position of the observer and the viewpoint position upon taking the selected image, thereby generating an image from the viewpoint position of the observer. In this manner, distortion of the image to be generated is suppressed. On the other hand, input multi-viewpoint images are converted into light rays that travel in a space, and each light ray is stored in a light space corresponding to a plane, which is one of a plurality of radially arranged reference planes and has an angle the plane makes with the light ray, which angle is closest to right angles. On the basis of the image, pixel positions, and pixel values calculated from the stored light rays, a desired image is generated, thereby broadening the observation range within which movement of the viewpoint position is allowed, and suppressing the required data volume.
摘要翻译：在多个视点位置拍摄的对象的图像与指示多个视点位置的信息一起输入，并且检测观察者的视点位置。基于检测到的观察者的视点位置来选择输入图像之一，并且在拍摄所选择的图像时根据观察者的视点位置和视点位置来确定图像的扫描线，从而生成来自观察者的视点位置的图像。以这种方式，抑制了要产生的图像的失真。另一方面，输入多视点图像被转换为在空间中行进的光线，并且每个光线存储在与作为多个径向布置的参考平面中的一个的平面相对应的光空间中，并且具有平面与光线成角度，该角度最接近直角。基于从所存储的光线计算的图像，像素位置和像素值，生成期望的图像，从而扩大允许视点位置的移动并抑制所需数据量的观察范围。

摘要： In order to enable plural users to share a virtual environment which includes not only simple shape data, but also data of an object having a highly complicated shape, a terminal equipment displays the virtual environment. The virtual environment is obtained when viewed by a user of the terminal equipment on the basis of tree-structure data composing the shape data, light space data and the like as components. The tree-structure data is changed when the shape data or the light space data is subjected to a process such as movement or the like. The changed information of the tree-structure data is transmitted to a server, and the server changes data in a data memory device based on the received changed information. The changed information is transmitted to another terminal equipment which displays the virtual environment obtained when viewed by the user of the another terminal equipment on the basis of the received changed information.

摘要： A virtual space using a geometric model for forming a virtual environment is input, nongeometric model object expression data based on a multi-viewpoint image is acquired, geometric information is added to the acquired nongeometric model object expression data, and the nongeometric model object expression data is used as an object arranged or operated in the virtual space using the added geometric information or automatically moving in the space. The same effect as that obtained when the shape data of an object having a very complex shape is generated or reproduced can be easily obtained without generating or reproducing the shape data. In addition, the entire virtual space can be generated without holding an enormous amount of light space data, so that the object can be operated in the three-dimensional space.

摘要： A three-dimensional measurement apparatus includes a model holding unit configured to hold a three-dimensional shape model of a measurement object and a determination unit configured to determine a distance measurement region on the measurement object based on information indicating a three-dimensional shape of the measurement object. The measurement object is irradiated with a predetermined illumination pattern by an illumination unit. An image of the measurement object is sensed while the illumination unit irradiates the measurement object. Distance information indicating a distance from the image sensing unit to the measurement object is calculated based on region corresponding to the distance measurement region within the sensed image. A position and orientation of the measurement object is calculated based on the distance information and the three-dimensional shape model.
