摘要
为了解决石油测井电视图像的实时有效传输和测井系统数据传输率低下的矛盾,提出了一种基于压缩感知的分块图像压缩方法,在满足测井系统的特殊要求,例如器件简单、功耗低、数据储存量小等,同时有效的压缩和重构图像。通过对井下图像的实验,分析压缩然后重构的图像,结果表明采用该方法能在简单的线性测量下得到高压缩比,并且重构后的图像仍能满足测井需要,符合测井系统的要求,提高了井下数据传输率。
To solve the conflicts between the effective real-time transmission of downhole video image and the low data transfer rate of the petroleum logging system, a block image compression algorithm based on compressed sensing is proposed. It could effectively compress and reconstruct image while meeting all particular requirements of the petroleum logging system, such as simplified device, low power consumption, small data storage. The experiment on the downhole image and the analysis on the compressed and constructed image indicate that, with this algorithm, a high compression ratio could be obtained, the constructed image could still meet the demand of logging system, and the downhole data transfer rate could be raised.
