虚实融合监控场景中的漫游路径规划方法

摘要

为了寻找不同视频之间的转换道路,提升观察者的方向感,提出一种虚实融合场景中的自动路径规划方法,首先提出一种视点评价方法,考虑在视频投影中的图像畸变带来的图像质量问题;然后设计了场景的视点采样方法和道路图,并基于视点评价结果为场景道路图的边定义权重;在确定视频的访问顺序之后,计算生成权重代价最小视点路径.在4个视频监控系统中验证了文中提出的视点评价方法和路径生成方法的有效性,证明其能够提升用户的虚拟观测体验.%We seek to develop an automatic path planning method to find the way of the transition and willing to help to improve the observer's sense of direction.We firstly propose a viewpoint quality metric which evaluates the quality of viewpoints by measuring the image distortion in video projection.Then we construct a graph for the scene whose nodes denote sample viewpoints and edges denote virtual camera movements.A camera path can be generated automatically using this graph.Finally we apply our method in video surveillance and demonstrate that it improves observers' visual experience.
