Video panorama mosaicing in autonomous PTZ tracking
PTZ自主跟踪中的全景视频生成

This paper proposed a method of generating video mosaic panorama in single autonomous PTZ tracking application, and this method can compose panorama video of an target object moving on large background image. Our approach can be potentially used in single PTZ surveillance and helpful in monitoring moving object in large scenes. The video mosaic panorama can be separated into target object and panorama background. We first utilize mean shift tracking algorithm to obtain the target region and then align adjacent images by combining vertical projection and harris corners of images, so that image registration can be acquired in real time, meanwhile the transforming parameters to background image are recorded. In the end the whole video mosaic is retrieved by superimposing the target region on the panorama background frame by frame. Compared with traditional method, this can be accomplished without manipulating camera or aligning frames by hand.
