遥感产品生产系统中产品算法的流程化处理

Flow Processing of Product Algorithm in Remote Sensing Products Production System

在遥感影像产品的生产过程中往往需要一个或多个算法,而算法之间的相互依赖关系的描述则会直接影响卫星产品生产时算法的执行能力以及规模化处理效率。因此,通过遥感产品共性,对卫星算法处理产品的流程进行分析,利用JGraph开源包将遥感卫星产品算法封装成其特有的组件,形成一种从影像输入到影像处理再到影像产品输出一体化管理的工作流。将此方法应用到国家民用空间基础设施"十三五"建设的相关平台中,研究结果不仅对算法处理产品的流程复杂程度进行了一定的优化,也在规范卫星产品生产流程中提高了卫星共性产品的生产效率。

In the production of remote sensing image products, one or more algorithms may be used. The description of the interdependence between product algorithms directly affects the algorithm’s execution ability and scale processing efficiency when satellite products are produced. Therefore, through the commonality of remote sensing products, the process of satellite algorithm processing products was analyzed. The JGraph open source package encapsulated the remote sensing satellite product algorithm into its unique components firstly, and then formed a workflow, which was a workflow for integrated management of image input to image processing and then image product output. This method was applied to the relevant platforms for the national Thirteenth Five-Year plan for civil space infrastructure. The results of the study not only optimizes the algorithm processing product process, but also improves the production efficiency of satellite common products in the standardization of the satellite product production process.
