Abstract

The invention provides a high-speed image transmission system applied to an unmanned aerial vehicle system. The system comprises an unmanned aerial vehicle signal sending system assembly and a ground signal receiving assembly. The unmanned aerial vehicle signal sending system assembly comprises a high-definition motion camera and a transmitter. The transmitter comprises an H264 coding unit and a transmitting antenna for transmitting a signal. The ground signal receiving assembly comprises a controller, a signal receiving antenna, an H264 decoding unit, a high-definition display screen and a code compiler. Before the H264 decoding unit carries out decoding processing, the code compiler compiles code required for the decoding processing in advance. When the H264 decoding unit carries out the decoding processing, a processing process is carried out by directly employing the compiled code. Some variables in the code can be decoded by the H264 decoding unit. The variables comprise frames, heights, the macro number of images, and parameters such as a quantification factor, and so on. The variables are taken as constants for compiling. A cpu register is no longer occupied. Parameter transmission is unnecessary. The integrated operation of the code is more efficient. An effect of improving the decoding efficiency by 30-50%% is achieved.

Description

[0001] [technical field] [0002] The invention relates to the technical field of UAV image transmission, in particular to a high-speed image transmission system applied to UAV systems with high decoding efficiency, fast operation speed and does not occupy too much system memory. [0003] [Background technique] [0004] In recent years, high-definition image transmission has been widely used in various industries, such as transportation, surveying, photography and other work that requires shooting and transmitting data. In addition to fixed-point monitoring image transmission, there is also real-time high-definition image transmission captured by UAVs, which puts forward higher requirements for the speed and response of image transmission. [0005] Most of the monitoring image transmission in the industry now takes up a lot of space, and the running speed cannot keep up with the update of the acquired image, resulting in image freeze and real-time synchronous transmission. Bas...
