摘　　要：针对PolSARpro软件自带高分三号数据转换模块无法自适应分布式差异化硬件环境问题,提出了一种按照该软件的数据格式要求进行分布式自适应负载均衡并行转换算法,将高分三号多极化数据快速、精确地进行定标与格式转换,对不同硬件配置环境自适应,能够抗数据偏斜,并且通过KingMap V10.5平台实现了算法并在实际数据中进行测试,试验结果表明性能提升了约12.7倍,验证了算法的可行性、高效性和正确性。In response to the issues of PolSARpro software's built-in GF-3 data conversion module being unable to adapt to distributed differentiated hardware environments,this paper proposes a distributed load balancing parallel conversion algorithm according to the data format requirements of its software,which can quickly and accurately calibrate and convert GF-3 multi-polarization data,adapts to different hardware configuration environments,and can resist data skew.and the algorithm is implemented on the KingMap V10.5 platform and tested on actual data.the experimental results show that the performance has been improved by about 12.7 times,which verifies the fea‐sibility,efficiency and correctness of the algorithm.
