基于i.MX6无人机视频码率受控的压缩系统设计
Design of the Embedded Video Compression System for Video Data Rate Controlled Based on i.MX6
摘要
Abstract
For the output bit rate of UAV airborne video compression system is unstable and the bandwidth of wireless channel is limited. This paper based on i.MX6 video processing hardware platform to compress video data that have been taken by H.264 standard. Basing on the motion estimation search range,the maximum spacing design of the key frames and using buffer rate control mechanisms to control the output bit rate,the problem of wireless channel's limited bandwidth is solved. The experimental results show that compared with the system which is not used the rate control mechanism;the proposed approach can guarantee the stable output bit rate and small amount of data after processing.关键词
