为提高信道利用率,对萤火一号(YH-1)火星探测器在轨图像处理技术进行了研究。给出了图像处理单元的图像压缩算法原理,设计了压缩图像数据传输的健壮差错控制方案,介绍了针对图像传输设计的图像预览和点播技术。试验结果表明:图像压缩流有较强抗误码特性。
In order to improve the channel utilization rate, the in-orbit image processing technology of firefly one (YH-1) Mars rover was studied. The principle of image compression algorithm of image processing unit is given. The robust error control scheme of compressed image data transmission is designed. The image preview and on-demand technology for image transmission are introduced. The experimental results show that the image compression stream has strong anti-error characteristics.
