[中文适用范围]： 本文档指定了一种基于图像的表示模型，该模型使用一组图像和可选的底层 3D 模型来表示目标对象/环境，以便在任意视点进行准确、有效的对象/环境表示。它适用于广泛的图形、虚拟现实和混合现实应用，这些应用需要使用各种对象和环境来表示场景的方法。 [外文原描述]： This document specifies an image-based representation model that represents target objects/environments using a set of images and optionally the underlying 3D model for accurate and efficient objects/environments representation at an arbitrary viewpoint. It is applicable to a wide range of graphic, virtual reality and mixed reality applications which require the method of representing a scene with various objects and environments. This document: — defines terms for image-based representation and 3D reconstruction techniques; — specifies the required elements for image-based representation; — specifies a method of representing the real world in the virtual space based on image-based representation; — specifies how visible image patches can be integrated with the underlying 3D model for more accurate and rich objects/environments representation from arbitrary viewpoints; — specifies how the proposed model allows multi-object representation; — provides an XML based specification of the proposed representation model and an actual implementation example (see Annex A).
