Example Embodiment
[0043] Example one
[0044] This embodiment provides an evaluation method of a multi-satellite earth observation mission planning algorithm, such as figure 1 As shown, the method includes the following steps:
[0045] Step 110: Read test data.
[0046] In this step, when the planning algorithm needs to be evaluated, test data is read from the database, and the test data includes observation tasks and receiving tasks. The database includes: satellite information table, payload information table, ground target information table, etc. Among them, the payload refers to the equipment carried by the satellite to obtain image data, such as cameras (hyperspectral, multispectral or panchromatic), synthetic aperture radar, etc. The ground target refers to a ground area that needs to be observed, including: point targets and regional targets.
[0047] Step 111: Call different planning algorithms to be evaluated to perform task planning on the test data, and obtain planning results;

Example Embodiment
[0134] Example two
[0135] Compared with the first embodiment, this embodiment provides a multi-satellite earth observation mission planning algorithm evaluation device, such as Figure 5 As shown, the device includes: a reading module 51, a calling module 52, a calculation module 53, and a comparison module 54; among them,
[0136] The reading module 51 is used to read test data.
[0137] Specifically, when the planning algorithm needs to be evaluated, the reading module 5 reads test data from the database, and the test data includes observation tasks and receiving tasks. The database includes: satellite information table, payload information table, ground target information table, etc. Among them, the payload refers to the equipment carried by the satellite to obtain image data, such as cameras (hyperspectral, multispectral or panchromatic), synthetic aperture radar, etc. The ground target refers to a ground area that needs to be observed, including: point targets and regional t...

[0224] Example three
[0225] In actual application, the device provided in the second embodiment can be integrated into a computer, and the user can evaluate the planning algorithm through the man-machine interface.
[0226] Specifically, first, the user can click "Database Configuration" in the toolbar to connect to the database. Read planning test data and start task scheduling.
[0227] After connecting to the database, the user selects the data for task planning from the database, clicks "batch number selection" in the tool bar of the man-machine interface, enters the batch number and clicks the "OK" button to obtain the observation metatask and receive metatask data. In addition, users can plan the data of multiple batch numbers at the same time as needed to achieve parallel planning.
[0228] Secondly, users can set different parameters to run the algorithm according to their needs, and plan the test data. Among them, the parameters of the evolutionary algorithm include popul...
