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.
