Embodiment Construction
[0043] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.
[0044] As mentioned in the background technology, the measurement accuracy of star observation is greatly affected by chromatic aberration, and the chromatic aberration problem may lead to blurred edges of star images, which will affect the outline of star images, photometric calibration, centering of star images, and astronomical positioning. Similarly, when observing space debris, it is also greatly affected by chromatic aberration. Among them, space debris refers to the product of human space activities. Including the rocket body and satellite body that has completed the mission, rocket jets, jettisons during the execution of space missions, and fragments...

The invention relates to a starry sky image color difference correction method, a device, a storage medium and spaceflight observation equipment. The method is applied to the spaceflight observation equipment. The spaceflight observation equipment is provided with a plurality of optical filters of different wave bands. The method comprises the following steps: obtaining a starry sky image corresponding to each wave band located at the same shooting position at the same moment; aiming at the starry sky image of each waveband, determining a star data set corresponding to the starry sky image; for the starry sky image of each waveband, determining the total mean square error of the starry sky image according to the right ascension mean square error and the declination mean square error of thestarry sky image; determining the minimum total mean square error in the total mean square errors of the starry sky images of all the wave bands, and determining the optical filter corresponding to the wave band corresponding to the minimum total mean square error as the target optical filter, so that the influence of chromatic aberration on the observation precision of the spaceflight observation equipment is eliminated, and the imaging quality of the starry sky images is improved. And the optical filter capable of reducing the influence of chromatic aberration on the observation and measurement precision to the maximum extent can be determined.
Description
technical field [0001] The present disclosure relates to the technical field of aerospace observation, and in particular, to a method, device, storage medium, and aerospace observation equipment for correcting chromatic aberration of starry sky images. Background technique [0002] In related technologies, the main means for scientific researchers to observe stars in geosynchronous orbits is ground-based optical observation. In ground-based optical observations, refracting astronomical telescopes are mainly used as observation platforms. The observation of stars is mainly based on positioning. In the process of using refracting astronomical telescopes to measure stars, chromatic aberration will affect the measurement accuracy of the telescope. Contents of the invention [0003] The purpose of the present disclosure is to provide a method, device, storage medium and aerospace observation equipment for correcting chromatic aberration of starry sky images, which solves the p...
