摘　　要：随着遥感影像质量提升和更新频率的加快,传统方式切片计算能力受限,为满足影像快速切片的需求,该文借鉴并行计算的思路,设计实现一套瓦片并行切片和基于瓦片合并的影像快速切片算法。从实验结果来看切片效率得到明显提升,有效解决单机切片效率低下的问题。With the improvement of remote sensing image quality and the acceleration of update frequency,the computing ability of traditional slicing is limited.In order to meet the needs of fast image slicing,this paper draws lessons from the idea of parallel computing.A set of tile parallel slicing and image fast slicing algorithm based on tile merging are designed and implemented.Based on the experimental results,the slicing efficiency is improved obviously,which effectively solves the problem of low efficiency of stand-alone slicing.
