The majority of computer vision applications assumes that the camera adheres to the pinhole camera model. However, most optical systems will introduce undesirable effects. By far, the most evident of these effects is radial lensing, which is particularly noticeable in fish-eye camera systems, where the effect is relatively extreme. Several authors have developed models of fish-eye lenses that can be used to describe the fish-eye displacement. Our aim is to evaluate the accuracy of several of these models. Thus, we present a method by which the lens curve of a fish-eye camera can be extracted using well-founded assumptions and perspective methods. Several of the models from the literature are examined against this empirically derived curve.
大多数计算机视觉应用都假定相机遵循针孔相机模型。然而，大多数光学系统都会引入不良影响。到目前为止，这些影响中最明显的是径向透镜效应，在鱼眼相机系统中尤为明显，在该系统中这种效应相对极端。几位作者已经开发出可用于描述鱼眼位移的鱼眼镜头模型。我们的目的是评估其中几种模型的准确性。因此，我们提出了一种方法，通过合理的假设和透视方法来提取鱼眼相机的镜头曲线。对照这条通过实验得出的曲线，对文献中的几种模型进行了检验。
