Problems solved by technology

[0009] When importing targets with a large number of vulnerable areas, each target needs to obtain results from a large amount of scene data through multi-dimensional matching such as time and space. At this time, the database calculation pressure is huge, which affects the execution efficiency of the database. Long waiting time and poor user experience;
[0010] Each piece of scene data needs to be separately processed for geographical location, which results in large data volume, slow execution, and huge pressure on the database

Abstract

The invention provides a demand closed-loop analysis method, system and device. The method comprises the steps of obtaining satellite scene data, obtaining demand data and carrying out demand timing coverage analysis and calculation. The method comprises the following steps: firstly, starting from two entrances of demand and scene data, carrying out small-amount operation in real time to obtain a certain incidence relation, and finally, summarizing and calculating coverage rate, observation times and observation duration, and sharing large calculation amount at the same moment in the prior art into small calculation amount at different moments, thereby reducing the calculation burden of a database and improving the calculation efficiency of the database. Therefore, the calculation efficiency is ensured, and the database pressure is reduced.

Description

technical field [0001] The invention relates to the technical field of satellite observation, in particular to a method, system and device for closed-loop demand analysis. Background technique [0002] At present, the demand closed-loop analysis in the field of satellite observation technology refers to the observation demand put forward by the user, and the completion of the demand is analyzed within a specified time through the obtained satellite image scene data. Generally speaking, the observation target comes from the vulnerability area and the specific area to be observed. There may also be multiple discrete areas, which need to be completed through multiple satellites, multiple transits, and multiple observations. This process is usually not completed in a very short period of time. We need to keep abreast of the completion of the requirements at all times. It is necessary to track the coverage shooting situation of the requirements in real time, and it can also provi...
