具有空间一致性的集成式混合现实三维用户创作工具

An Integrated Mixed Reality 3D Authoring Tool with Spatial Consistency

针对目前的混合现实用户创作工具对真实世界空间提示信息缺乏,以及对虚拟物体构建能力偏弱的问题,提出具有空间一致性的集成式混合现实三维用户创作工具.首先通过对自然特征的提取建立具有二维及三维信息的相对参照空间,然后识别已知尺度标志物,把相对参照空间转化为具有空间一致性的绝对参照空间,通过与商用三维数字内容创作工具的集成实现高效的虚拟物体构建与注册.实验结果表明,该工具能够实现"高效创作、准确注册"的目标.

It is often a non-intuitive and tedious task to develop mixed reality （MR） applications due to the difficulty of accurate 3D registration and the inconvenience of virtual 3D model creation. In this paper, we propose a novel integrated mixed-reality 3D authoring tool. In order to achieve accurate registration with high geometric consistency, both natural features and artificial markers are employed and combined for robust structure-from-motion computation. In order to efficiently construct virtual objects with accurate registration, the proposed authoring tool is integrated into a commercial package of 3D digital content creation. The experimental results demonstrate that the proposed authoring tool can achieve the objective of efficient virtual model construction and accurate registration.
