Distributed image cutting task allocation method and device and distributed image cutting system

The invention relates to the field of image processing, and specifically relates to a distributed image cutting task allocation method and device and a distributed image cutting system. The method comprises: acquiring spatial distribution information of all picture files in a to-be-cut picture range, encoding the picture files by adopting a spatial filling curve according to the spatial distribution information, and distributing the picture files to a task execution end in sequence according to the encoding. The embodiment of the invention is applicable to a distributed image cutting system and task distribution of distributed image cutting, the number of generated tile fragments can be effectively reduced, and the fragment merging efficiency is improved, so that the image cutting efficiency is improved. 本发明涉及图像处理领域，具体地涉及一种分布式切图任务的分配方法、分布式切图任务的分配装置及分布式切图系统，所述方法包括：获取待切图范围内所有的图幅文件的空间分布信息，依照空间分布信息将这些图幅文件采用空间填充曲线进行编码，按照所述编码依序将所述图幅文件分配至任务执行端。本发明实施例适用于分布式切图系统以及分布式切图的任务分配，能够有效减少瓦片碎片的产生数量，并提高碎片合并的效率，从而提升切图的效率。
