摘要
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。
To improve the channel efficiency, the onboard image processing technique for YH-1 Mars probe was studied in this paper. The principle of the image compression algorithm for the image processing unit was given out. A reliable error controlling scheme was developed to deal with the transmission of the compressed image data in the deep-space channel. The techniques of the image preview and on demand for the image transmission were introduced. The simulation experiment results showed that the image compression had the characteristic of high error resilience.
