The evaluation method comprises the following steps: acquiring original optical image dataof actual imaging of an on-orbit satellite; acquiring image data of a full-link simulation system corresponding to the original optical image; determining a first-level evaluation index, and evaluating the full-link simulation system according to the first-level evaluation index; obtaining an evaluation result of the full-link simulation system, and determining a secondary evaluation index corresponding to the evaluation result according to the evaluation result; and calculating an evaluation index of the image data of the full-link simulation system according to the secondary evaluation index calculation result. In this way, objective index evaluation of corresponding level stages can be carried out according to different remote sensing technology levels, target interpretation can be oriented, auxiliary support of problem analysis bases and simulation image availability conclusions can be provided, and the reproducibility of the simulation technology for satellite imaging system performance can be effectively verified.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to an evaluation method, device, electronic equipment and medium for visible light full-link simulation images. Background technique [0002] The evaluation of simulation results is an important part of simulation technology. With the improvement of theory and technology and cognition ability, the repetition of cognition→practice→recognition→repractice will gradually improve the authenticity of simulation. According to different simulation objects, purposes and needs, the requirements for simulation evaluation indicators are also different. The evaluation results are an important reference to determine whether the simulation results meet the expected goals, and are also an important support for the promotion and application of results. [0003] The development of a full-link simulation system for optical imaging can provide technical support for the demonstration design, deve...

AI Technical Summary

Problems solved by technology

[0004] 1) Some research results have been formed in the field of remote sensing image quality evaluation, but they cannot reflect the similarity and credibility between the simulated image and the real image, and there is a problem that the evaluation index does not match the simulation ability

[0005] 2) For applications such as object-oriented interpretation, although subjective evaluation can obtain more reliable and accurate results, subjective evaluation consumes a lot of manpower and time, and is often not stable enough, which is not conducive to real-time online evaluation and system automated feedback processing
