摘要
针对无人机侦察图像及其在军事运用上的特点,分析并证明了基于小波变换的压缩技术在无人机侦察图像压缩方面是一种很好的解决方案,根据某型无人机侦察图像设计了一种基于小波变换的分区域压缩算法,取得了良好且满意的图像压缩效果和实时传输效果。最后,阐述了基于小波变换的侦察图像压缩的关键技术。
Aimed at the reconnaissance images of unmanned aerial vehicle （UAV） and its characters in military applications, the compression technology based on wavelet transform is proved to be a good solution for the reconnaissance image compression of UAV. A leaveregion compression algorithm is designed based on the wavelet transform for the reconnaissance images of a certain model UAV. The result of the image compression and the real-time transmission are satisfied. Finally, the key technologies of the reconnaissance image compression are described based on the wavelet transform.
