Abstract: A telepresence system, a telepresence method, and a video collection device are disclosed. The telepresence system includes a video collection device, a video display device, an audio collection device, an audio player, and an audio and video communication device. The audio and video communication device transmits videos collected by the video collection device on a local end and audios collected by the audio collection device on the local end to a remote end through a network; the video display device and the audio player on the remote end play the images and audios respectively; and the video collection device is a panoramic camera. The technical solution under the present invention overcomes the poor effect of panoramic presence in the existing telepresence system, and improves the telepresence system in terms of depth presence, seamless display and eye contact.

Abstract: Embodiments of the present invention provide a method and a device for multi-camera image correction. The method for multi-camera image correction includes: acquiring information of independent images that are captured by each camera and have no overlap area or have an overlap area smaller than a threshold; acquiring, according to information of each independent image, an image correction parameter that corresponds to each camera and allows adjacent independent images to be corrected into a contiguous image; and performing, according to the image correction parameter, correction processing on video data of a camera that corresponds to the image correction parameter. In the embodiments of the present invention, maintenance manpower is saved, adjustment efficiency is improved, and remote maintenance may be performed in the case of no overlap area or of a small overlap area. In addition, images are corrected in a data processing manner, which efficiently ensures precision of image correction.
