由于增强现实和虚拟现实体验的日益普及，在多个维度上捕捉真实的世界并以沉浸式方式将其呈现给用户的兴趣从未如此高。分发这种表示使用户能够在多感官3D媒体体验中自由导航。不幸的是，这样的表示需要大量的数据，在当今的网络上传输是不可行的。内容链中采用的高效压缩技术需求量很大，是增强现实和虚拟现实应用民主化的关键组成部分。作为处理多媒体的主要标准化组织之一，运动图像专家组确定了这一趋势，并于最近开始建立一个用于表示3D点云的计算机的开放标准，3D点云是非常知名的2D像素的3D等价物。本文介绍了这一正在进行的标准化工作的主要发展和技术方面。
Due to the increased popularity of augmented and virtual reality experiences, the interest in capturing the real world in multiple dimensions and in presenting it to users in an immersible fashion has never been higher. Distributing such representations enables users to freely navigate in multisensory 3D media experiences. Unfortunately, such representations require a large amount of data, not feasible for transmission on today's networks. Efficient compression technologies well adopted in the content chain are in high demand and are key components to democratize augmented and virtual reality applications. Moving Picture Experts Group, as one of the main standardization groups dealing with multimedia, identified the trend and started recently the process of building an open standard for compactly representing 3D point clouds, which are the 3D equivalent of the very well-known 2D pixels. This paper introduces the main developments and technical aspects of this ongoing standardization effort.
