Abstract: In order to meet the diversified requirements of airborne display, this paper proposes a video conversion and overlay technology based on FPGA. The technology takes FPGA as the core, and is equipped with peripheral circuits such as decoding circuit and signal conversion circuit, which can realize the conversion of XGA and PAL analog video signals to RGB digital video signals, and overlay display with digital image signals. It has strong versatility and flexibility. The experimental results show that the video conversion and overlay technology can meet the requirements of stable, reliable and highly integrated picture display of airborne displays, and has high application value.

引言
隨著機(jī)載顯示技術(shù)的不斷發(fā)展,作為核心支撐的視頻圖像處理技術(shù)要求不斷提高,它與飛行安全性和任務(wù)執(zhí)行效率密切相關(guān),更是推動(dòng)航空電子系統(tǒng)向智能化、集成化方向發(fā)展的關(guān)鍵[1]。本文旨在研究一個(gè)基于FPGA的視頻處理硬件平臺(tái)[2],通過接收?qǐng)D形產(chǎn)生模塊產(chǎn)生的R、G、B數(shù)字圖像信號(hào)及顯示處理機(jī)輸出的外部視頻信號(hào),按照總線命令對(duì)相應(yīng)圖像進(jìn)行疊加處理,最后產(chǎn)生LVDS信號(hào)驅(qū)動(dòng)液晶顯示模塊顯示,同時(shí)輸出DVI格式記錄視頻。該視頻處理平臺(tái)不僅有效降低了硬件成本與系統(tǒng)復(fù)雜度,而且顯著提升了信息顯示效率與可靠性。
