Embodiment

[0032] In this embodiment, a method for managing spaceborne imaging data based on multi-level file symbols of the present invention includes the following steps:

[0033] Step 1. Based on the task planning of the imaging data, according to a task corresponding to a first-level file symbol, the ground system specifies the first-level file symbol;

[0034] Step 2. Based on the classification level of the imaging data, one classification corresponds to a first-level file symbol, and one type of content corresponds to a same-level file symbol, and the satellite system independently defines the file symbol level by level;

[0035] Step 3. When the satellite is directional and returned, according to the data classification method, the ground system specifies the file symbol and extracts the corresponding imaging data;

[0036] Step 4: After the information is used, the ground system specifies the file symbol, clears the corresponding imaging data, and releases the file symbol.

Abstract

The present invention relates to a spaceborne imaging data management method based on a multi-level file symbol in the field of spaceborne imaging data management technology, comprising the following steps: Step 1. Based on the task planning of the imaging data, the ground system specifies the first-level file symbol; Step 2: Based on the classification level of the imaging data, the satellite system independently defines the file symbol level by level; Step 3: According to the data classification method, the ground system specifies the file symbol and extracts the corresponding imaging data; Step 4: The ground system specifies the file symbol and clears the corresponding Imaging data, release file symbol. The present invention is applicable to the field of space-borne imaging data management, solves the problem of disordered data classification in the space-borne imaging data management method, improves the efficiency of on-board task execution, enhances the flexibility of ground manipulation, and can adapt to the diverse imaging capabilities of satellites .

Description

technical field [0001] The invention relates to the technical field of spaceborne imaging data management, in particular to a method for managing spaceborne imaging data based on multi-level file symbols. Background technique [0002] The spaceborne imaging data management method refers to remote sensing satellites using certain parameters as the control object, and according to certain association rules, the imaging data is classified, stored, transferred, extracted, and cleared, and it also includes the method of ground system control satellites. [0003] With the intelligent development of remote sensing satellite imaging technology, identification technology and control technology, satellite imaging has higher precision, more times, and wider range. In the task, the comprehensive ability of performing fixed-point identification and imaging autonomously after implementing wide-area search imaging, the satellite imaging process is more targeted at the target area, the data...
