基于VMIC实时网络高速图像传输研究

红外成像导引头是精确制导武器中最关键的组成部分。在现代红外成像导引头半实物仿真项目中,高速实时图像对传输速率要求较高。目前广泛使用的VMIC实时网络在冗余传输模式下的传输速率不能满足要求。首先提出了双卡结构的实时网这种解决办法;同时针对空空导弹目标场景的稀疏性,提出了采用压缩、解压率较高的QuickLZ算法进行压缩后传输的办法。目前,提出的两种解决方案已经成功实测于某制导武器的红外成像导引头半实物仿真试验中。

Research on High-speed image Transmission Based on VMIC Real-time Network

IR image seeker is the most crucial part in the precision-guided weapons. As there was a high transmission rate requirement of the high-speed real-time image in the Hardware-in-the-loop simulation project of the modern IR image seeker, the transfer rate of the VMIC real-time network widely used currently in redundant transmission mode can not meet the requirements .Firstly, this paper propose a kind of dual-card structure of real-time network to solve this problem; and due to the sparsity of the target scene of the air-to-air missile, another solution is using QuickLZ algorithm with a higher compression ratio to compress image before transferred. At present, these two kinds of methods have used in the Hardware-in-the-loop simulation experiment of some precision-guided weapon.
