Different methods based on photogrammetry or self-calibration exist to calibrate intrinsic and extrinsic camera parameters and also for data pre- and post-processing. From a practical viewpoint, it is quite difficult to decide which calibration method gives accurate results and even whether any data processing is necessary. This paper proposes a set of optimal conditions to resolve the calibration process accurately. The calibration method uses several images of a 2D pattern. Optimal conditions define the number of points and the number of images to resolve the calibration accurately, as well as positions and orientations from where images should be taken.
基于摄影测量或自校准的不同方法可用于校准相机的内参和外参，也可用于数据的预处理和后处理。从实际角度来看，很难确定哪种校准方法能给出准确的结果，甚至难以确定是否需要进行任何数据处理。本文提出了一组优化条件，以准确解决校准过程。该校准方法使用二维图案的多幅图像。优化条件定义了准确求解校准所需的点数和图像数量，以及拍摄图像的位置和方向。
