    摘要:

    北斗三代卫星技术在电力方面的短报文通信和定位技术应用日趋成熟,但利用北斗短报文进行电力应急通信图像传输的相关研究尚不完善,尤其是图像经北斗短报文传输后的失真问题解决不够理想。本文提出了一种面向北斗短报文的渐进式传输图像恢复算法,首先以JPEG2000图像压缩算法为例,分析了渐进式图像传输技术与北斗短报文的特点,然后提出了JPEGRE图像恢复算法,利用峰值信噪比与结构相似性参数反映算法性能,最后通过实验方法证明JPEGRE图像恢复算法与其它流行算法相比具有更好的恢复能力。本文研究旨在提高有损压缩后图像恢复程度,辅助电力应急时做出更优的应急方案。

    Abstract:

    The application of Beidou three-generation satellite technology in short-message communication and positioning technology in power is becoming more and more mature, but the related research on using Beidou short-messages for power emergency communication image transmission is not perfect, especially after the images are transmitted through Beidou short-messages. The resolution of the distortion problem is not ideal. This paper proposes a progressive transmission image recovery algorithm for Beidou short messages. First, taking the JPEG2000 image compression algorithm as an example, the characteristics of the progressive image transmission technology and Beidou short messages are analyzed, and then the JPEGRE image recovery algorithm is proposed. The peak signal-to-noise ratio and structural similarity parameters are used to reflect the performance of the algorithm. Finally, the experimental method proves that the JPEGRE image restoration algorithm has better restoration ability than other popular algorithms. The purpose of this research is to improve the degree of image recovery after lossy compression, and to make a better emergency plan when assisting power emergencies.
