摘  要：隨著遙感影像質(zhì)量提升和更新頻率的加快，傳統(tǒng)方式切片計算能力受限，為滿足影像快速切片的需求，該文借鑒并行計算的思路，設(shè)計實現(xiàn)一套瓦片并行切片和基于瓦片合并的影像快速切片算法。從實驗結(jié)果來看切片效率得到明顯提升，有效解決單機切片效率低下的問題。

Abstract： 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.
