Embodiment 1
[0043] Please refer to figure 2 , The embodiment of the present invention provides a telepresence video image transmission method. The method includes:
[0044] 101. Use N cameras to collect N video images, where N is a positive integer not less than 2.
[0045] A telepresence system can use a three-eye camera to collect video images. Such as image 3 As shown, the three-eye camera has three cameras, but if the optical centers of the three cameras do not coincide, the video images collected by adjacent cameras may overlap or be missing during subsequent stitching.
[0046] Preferably, the embodiment of the present invention may use a common optical center camera to collect video images. The common optical center camera includes N common optical center cameras. When shooting, the positions of the optical centers of the N common optical center cameras overlap and remain unchanged, so that the edges of the viewing angles of adjacent cameras are aligned. Suppose there are three commo...
Embodiment 2
[0070] Please refer to Picture 11 The embodiment of the present invention also provides a telepresence video image transmission method. The method includes:
[0071] 201. Select an image area to be viewed, and send the description data of the image area to the sending end.
[0072] The user at one end of the telepresence system can select the image area that needs to be viewed. The selected image area can be included in the camera area of one camera, or it can span the camera area of two or more cameras.
[0073] In one implementation, the user can select the image area to be viewed by the following method:
[0074] 2011. Receive a panoramic image sent by a sending end, where the panoramic image is formed by splicing N channels of video images collected by the sending end, and N is a positive integer not less than 2.
[0075] Such as Figure 5 As shown, suppose there are three cameras at the sending end, and the collected video images are A, B, and C. The widths of A, B, and C are...
Embodiment 3
[0085] The foregoing first and second embodiments respectively illustrate the principle of the method of the present invention from the perspective of the transmitting end and the receiving end. Based on the foregoing description, the method of this embodiment may have more optional implementation modes.
[0086] Optionally, during the telepresence process, the sending end can first interact with the receiving end to obtain the screen resolution of the receiving end, and send a panoramic image scaled according to the screen resolution of the receiving end to the receiving end. Select an image area on the panoramic image, send the image area description data to the sending end, and the sending end intercepts the video of the image area and sends it to the receiving end in the form of another video stream. The selected image area may be contained within the shooting area of one camera or span the shooting areas of multiple cameras. The receiving end can view both the panoramic im...
