Abstract

The invention discloses a layered representation-based unmanned plane video adaptive transmission method. A device for realizing the method comprises a layered structure for video representation, wherein the layered structure sequentially comprises a background layer, an object layer and an enhancement layer from bottom to top. According to different requirements, a corresponding layered structure is selected to transmit a video, and the problem that the movement of an independent moving object in the video is vague and cannot be recognized after the independent moving object is compressed is solved by dividing the moving object. A clear panoramic picture can be provided, or a video sequence with relatively high quality can be provided. The output precision is improved, the compression time is greatly shortened, and the working efficiency is improved to a great extent.

Description

technical field

[0001] The invention relates to a video screen transmission method, in particular to a method for self-adaptive transmission of UAV video based on layered expression. Background technique

[0002] UAV (Unmanned Aerial Vehicles, UAV) is a hot spot in the development of military weapons in the world today, and will likely become the leading force in air combat in the 21st century, widely used in battlefield reconnaissance, surveillance, border patrol, electronic reconnaissance, target Positioning, tracking and identification, etc. [1]. In addition, UAVs can also be used for civilian surveying and mapping, road inspection, site monitoring, flood monitoring, etc. As far as the current situation is concerned, the role of most UAVs is based on the premise of airborne surveillance capabilities, which will depend on the collection, compression and transmission of video and images [2][3][4]. After decades of application and development, the UAV image transmission sy...
