In order to cooperate with this display solution, the existing technology uses image processing software or video processing software for processing, which is time-consuming and labor-intensive. In addition, since a circular rotation is required, only the required information is displayed, while in the existing solution, all data is uniformly rotated during rotation. This processing solution is feasible for cases where the data scale is relatively small. However, for cases where the data scale is relatively large (more than 100 pictures), the processing speed is slow and the resource consumption is high. Summary of the invention
