摘要
本文首先阐述了基于FPGA和ARM的雷达视频混合显示技术的必要性,介绍了该显示技术的工作原理,以及视频处理通道的工作原理,对Camera接口、ITU-R BT601/656视频编码、显示控制器视频混合叠加、高分辨显示数据的实时混合等工作原理分别进行了阐述,详细分析了雷达视频混合显示是如何利用上述原理来实现。通过工程试验,验证了该显示技术的有效性。
Firstly, the article has an explanation on the necessity of radar video integrated display technology based on FPgA and ARM. Then, it introduces the operation principle of this display technology and video processing channels. Through explanation on the principles including camera interface, ITu-R BT601/656 video coding, video mixing overlapping of display controller, data real-time mixing with high resolution etc. Also, there is detailed analysis on how to fulifll radar video mixing display via the above-mentioned principles. Through engineering trials, the feasibility of this display technology is veriifed.
