近来，已经开发了许多类型的全向相机，并且在许多不同的领域中引起了很多关注。特别是，多相机类型的全向相机具有高分辨率和对于任何视角方向几乎均匀的分辨率的优点。提出了一种运动全方位多摄像机系统（OMS）的摄像机外参数恢复方法。首先，我们讨论了一个角度的n点（PPENS）问题的OMS，然后描述了一个实用的方法来估计外部相机参数从多个图像序列获得的OMS。所提出的方法是基于使用的形状从运动和的PADER技术。
Recently, many types of omni-directional cameras have been developed and attracted much attention in a number of different fields. Especially, the multi-camera type of omni-directional camera has advantages of high-resolution and almost uniform resolution for any direction of view. In this paper, an extrinsic camera parameter recovery method for a moving omni-directional multi-camera system (OMS) is proposed. First, we discuss a perspective n-point (PnP) problem for an OMS, and then describe a practical method for estimating extrinsic camera parameters from multiple image sequences obtained by an OMS. The proposed method is based on using the shape-from-motion and the PnP techniques.
