摘要

我们提出了一种估计具有可能变化焦距的旋转摄像机的运动参数的方法。该方法适用于体育赛事视频的分析。估计过程包括三个阶段:(1)二维平动分量的鲁棒估计;(2)基于二维分块的运动估计;(3)参数运动模型的鲁棒估计。为了提高可靠性，引入了二维运动矢量的置信度度量。在一些困难的真实图像序列上验证了该方法的可靠性。

Robust pan, tilt and zoom estimation

We propose a method for estimating the motion parameters for a rotating camera with a possibly changing focal length. This method is suitable for analysing sport event videos. The estimation process consists of three stages: (1) robust estimation of the 2D translational components; (2) 2D block-based motion estimation; (3) robust estimation of a parametric motion model. For more reliability, confidence measures for the 2D motion vectors are introduced. The reliability of the method is illustrated on some difficult real image sequences.
