从单个移动相机的图像生成相机姿态的标准方法是从运动恢复结构（SfM）。当瞄准SfM的实际实现时，通常需要重量轻且体积小的相机。这项工作分析，这是最好的相机和透镜的SfM，这是小尺寸和市场上。因此，我们比较了鱼眼镜头和透视镜头的相机。结果表明，鱼眼透镜提高了姿态估计。并讨论了如何进一步利用大视场来提高姿态估计的方法。
A standard approach to generate a camera pose from images of a single moving camera is Structure From Motion (SfM). When aiming on a practical implementation of SfM often a camera is needed that is lightweight and small. This work analyses which is the best camera and lens for SfM, that is small in size and available on the market. Therefore we compare cameras with fisheye and perspective lenses. It is shown that pose estimation is improved by a fisheye lens. Also some methods are discussed, how the large Field of View can be further exploited to improve the pose estimation.
