摘要
多视角的标定和自标定是多视角系统部署和应用中的重要限制环节。文章针对基于单应关系的多视角跟踪应用场景,提出了一种使用跟踪结果本身进行视角几何关系标定的方法,避免了预先标定环节,可以配合现有的各种跟踪算法。理论分析和仿真实验表明,此方法具有高效率、高可靠性、易于实施的特点。
A multi-view tracking system can gain better performance than single-view ones through information exchange. Nevertheless, it relies on the known projective relationship among views. Calibra- tion or self-calibration plays a very important role in both the deployment and the operation of multi-view tracking systems. In this paper, a method to tackle the homography relationship with locations of tracked objects is proposed, which needs no pre-calibration process of information and can cooperate with existing muhi-view tracking framework. By theoretical analysis and simulation experiment, this method is proved to be efficient, reliable and easy to be deployed.
