全方位摄像机可提供周围环境的360度全景视图，最近已用于许多应用，如机器人，导航和监控。本文介绍了应用运动估计的全向摄像机进行环境分析，使用车载摄像机。该系统通过补偿自运动和检测具有独立运动的物体来检测和跟踪周围的车辆。关于自我运动和校准的先验知识与来自图像梯度的信息最佳地组合以获得更好的运动补偿。
Omni-directional cameras which give 360 degree panoramic view of the surroundings and have recently been used in many applications such as robotics, navigation and surveillance. This paper describes the application of motion estimation on omni camera to perform surround analysis using an automobile mounted camera. The system detects and tracks the surrounding vehicles by compensating the ego-motion and detecting objects having independent motion. Prior knowledge about ego-motion and calibration is optimally combined with the information from the image gradients to get better motion compensation.
