摘要

平面镜可用于生成虚拟摄像机，并从多个视角捕捉场景。然而，由于镜像还原的原因，由此产生的相机-镜子设置校准起来非常麻烦。典型的校准缺陷是忽略棋盘对称性和假设虚拟摄像头为前视角。本文解释了后视抽象概念及其在校准相机-镜子设置以获得等效无反光镜配置中的作用。本文回顾了基本理论，包括相机成像、校准过程和反射定律。通过校准照相机-镜子装置，然后使用校准后的照相机合成镜像，说明了所提出的方法。这项工作为校准更复杂的系统（如镜像相机-投影仪轮廓仪）提供了实用的见解。

Flat mirrors, virtual rear-view cameras, and camera-mirror calibration

Flat mirrors are useful to generate virtual cameras and capture a scene from multiple viewpoints. However, the resultant camera-mirror setup is cumbersome to calibrate because of the mirror image reversion. The typical calibration flaws are omitting the checkerboard symmetry and assuming that virtual cameras are front-view. This paper explains the rear-view abstraction and its usefulness in calibrating a camera-mirror setup to obtain the equivalent mirrorless configuration. The underlying theory is reviewed, including camera imaging, the calibration process, and the laws of reflection. The proposed approach is illustrated by calibrating a camera-mirror setup and then using the calibrated camera to generate mirror images synthetically. This work offers a practical insight into calibrating more sophisticated systems such as mirrored camera-projector profilometers.
