摘要

为了满足机载航电系统视频信号采集的要求，提高机载视频分配器的信号传输质量，提出了一种自适应均衡补偿方法，并将其应用于机载DVI (digital Visual Interface)视频信号分配器。该方法的优点是:利用硬件预强调和均衡技术，解决了DVI信号在长电缆传输过程中的失真问题;采用基于加权概率均衡模型的双直方图均衡方法，进一步提高了图像的对比度和清晰度。最后，实验表明，该方法可以提高视频图像的清晰度和识别率。

The adaptive equalization compensation algorithm for DVI video signal

In order to meet the requirements for collecting video signals of airborne avionics systems and improve the signal transmission quality of airborne video distributors, an adaptive equalization compensation method is proposed and applied to the airborne DVI (Digitial Visual Interface) video signal distributor. The advantages of this method are: using hardware pre-emphasis and equalization technology to solve the problem of distortion of DVI signals during long cable transmission; using a double histogram equalization method based on a weighted probability equalization model to further improve image contrast and sharpness. Finally, experiments show that this method can improve the clarity and recognition of video images.
