無人機(jī)（UAV）投入作戰(zhàn)使用的最大優(yōu)勢一直體現(xiàn)在情報(bào)偵察上，而視頻圖像信號是無人機(jī)的主要偵察信息，因此，視頻記錄儀是無人機(jī)系統(tǒng)一個(gè)重要的信息獲取手段。當(dāng)前，各種類型的無人機(jī)使用的視頻記錄儀主要是還是模擬視頻記錄儀，記錄載體一般是磁帶,這對視頻的后期處理和分析帶來了很大的不便.有效的解決方法就是實(shí)現(xiàn)視頻信息的數(shù)字化，并利用數(shù)字壓縮算法壓縮視頻信息的容量。VxWorks 是嵌入式實(shí)時(shí)操作系統(tǒng)，可靠性高，穩(wěn)定性好。此文研究了VxWorks 平臺的嵌入式視頻記錄儀的實(shí)現(xiàn)。

Abstract: the information reconnaissance has been the biggest advantage in the UAVs
application, and the video image signal is the major UAV reconnaissance information. Video
Recorder is an important means of access to information in UAV systems. At present, most of
video recorder in use is analog recorder with tape. This has brought a lot of inconvenience to video post-processing and analysis. The effective solution realizes the video information digitization, And use of digital video compression algorithm compresses information capacity. VxWorks is a strong RTOS, this thesis researched design and Implementation of video recorder on UAV based on VxWorks.
