摘　　要：针对最小包围盒中的最小体积轴向包围盒问题,提出基于增强现实的虚拟测量方法。该方法首先利用增强现实的虚实注册技术实现真实空间和虚拟空间的尺度对准,然后通过人机交互机制操作虚拟标尺对空间中三维物体进行匹配,标定其最小体积轴向包围盒。最后以玩具声级检测基准框标定任务为例对虚拟测量方法进行实验验证,实验证明该测量方法对最小体积轴向包围盒的标定误差在3%以下。The issue of determining the minimum-volume axis-aligned bounding box for a given 3D object was discussed. A virtual measurement approach was presented with augmented reality techniques. One of two essential ingredients in the proposed method is the alignment of an object in the real and virtual environment with respect to each other based on the registration principle. Another one is the implementation of virtual measurement with the human-machine interaction. Our approach was experimentally verified in the context of measuring the toy＇ s reference box in noise test. The result shows that the relative errors of the resultant measurements are less than 3%.
