Fish-eye lenses are convenient in such applications where a very wide angle of view is needed, but their use for measurement purposes has been limited by the lack of an accurate, generic, and easy-to-use calibration procedure. We hence propose a generic camera model, which is suitable for fish-eye lens cameras as well as for conventional and wide-angle lens cameras, and a calibration method for estimating the parameters of the model. The achieved level of calibration accuracy is comparable to the previously reported state-of-the-art.
鱼眼镜头在需要非常宽视角的应用中很方便,但由于缺乏准确、通用且易于使用的校准程序,它们在测量目的方面的应用受到了限制。因此,我们提出了一种通用相机模型,它适用于鱼眼镜头相机以及传统和广角镜头相机,还提出了一种用于估计模型参数的校准方法。所达到的校准精度水平与先前报道的最先进水平相当。
