本文提出了一种结构简单的三维测量系统。所提出的系统包括一个鱼眼透镜和一个圆筒，其内部由银反射层涂覆的相机。将目标物体放置在圆柱体内，并由相机从正上方捕获图像。捕获的图像包括从多个视点观察的点集：一个是直接观察的，另一个是通过镜子观察的。因此，可以在单次拍摄中使用立体视觉测量物体的整个形状。一个实际的实验情况进行了模拟和准确性进行了评估。此外，还实现了一个原型系统，并对真实的物体进行了形状测量
This paper proposes a three-dimensional measurement system with a simple structured system. The proposed system consists of a camera with a fish-eye lens and a cylinder whose inside is coated by a silver reflective layer. A target object is placed inside the cylinder and an image is captured by the camera from right above. The captured image includes sets of points that are observed from multiple viewpoints: one is observed directly, and the other is observed via the mirror. Therefore, the whole shape of the object can be measured using stereo vision in a single shot. An actual experimental situation was simulated and the accuracy is evaluated. In addition, a prototype system was implemented and the shape of the real object was measured
