Title:
DYNAMIC PROCESSING METHOD AND APPARATUS BASED ON UNMANNED AERIAL VEHICLE VIDEO PYRAMID MODEL
Document Type and Number:
WIPO Patent Application WO/2023/066412
Kind Code:
A1
Abstract:
The present disclosure relates to the field of video data real-time transmission and processing. Disclosed are a dynamic processing method and apparatus based on an unmanned aerial vehicle video pyramid model, which are used for solving the problems of the rendering efficiency of an unmanned aerial vehicle video being low, the system operation not being smooth, etc. The method comprises: constructing an unmanned aerial vehicle video pyramid model; and by using the unmanned aerial vehicle video pyramid model and according to a video loading request, performing resampling and segmentation by means of a video server, and performing dynamic scheduling and rendering, loading and displaying on a processed unmanned aerial vehicle video by means of a client. By means of the dynamic processing method for an unmanned aerial vehicle video provided in the present disclosure, unmanned aerial vehicle video data similar to the current map resolution can be dynamically loaded by using an unmanned aerial vehicle video pyramid model and according to a viewpoint distance and a field-of-vision range of the current scene view camera, such that high-performance on-demand rendering of a multi-resolution unmanned aerial vehicle video is realized, thereby ensuring the high efficiency of scene displaying and the smoothness of system operation.
