Embodiment Construction
[0033] The implementation process of the present invention is described below with a specific case.
[0034] Operations on the server side:
[0035] (1) Project the collected original panoramic video (3D) to a plane (2D) by means of equidistant cylindrical projection;
[0036] (2) Divide the planar image obtained by projection into blocks, and mark each block with the coordinates of its upper left corner;
[0037] (3) Divide the video into short video sequences of 2 seconds;
[0038] (4) Perform saliency detection for each short video, predict the focus area of the video, and record the block coordinates of the focus area;
[0039] (5) For each short video, the server stores three backups, corresponding to the perspectives of three positions in the panoramic video, the blocks within the visible range and the blocks in the focus area are compressed with high quality, and other blocks are compressed with Low quality compression.
[0040] The process of video transmission: ...
