Abstract

The present invention is applicable to the technical field of solar image offset detection, and provides a solar extreme ultraviolet image offset detection method, device and electronic equipment. The method includes: collecting the solar extreme ultraviolet image as a reference image; The ultraviolet image is used as a real-time image; comparing the gray value of the pixels in the benchmark reference image and the real-time image, calculating the offset between the acquisition times corresponding to the real-time image and the benchmark reference image respectively, so that the sun The deviation detection error of the extreme ultraviolet light image is greatly reduced, the reliability is greatly improved, and the spectroscopic imaging of the main optical path of the solar extreme ultraviolet imager is realized, and the structure is compact.

Description

technical field [0001] The invention belongs to the technical field of solar image offset detection, and in particular relates to a solar extreme ultraviolet image offset detection method, device and electronic equipment. Background technique [0002] In the image of the sun, there are various active phenomena. In solar images, solar extreme ultraviolet light is an important content of space weather research. Therefore, the research on space weather can be better promoted by researching and detecting the offset of the solar extreme ultraviolet light image. [0003] At present, when researching the offset of solar extreme ultraviolet light images, the solar extreme ultraviolet imager adopts the method of adding visible light four-quadrant guiding mirror to detect the offset of solar images. Although this method is simple in structure and easy to Ground experiment verification, but the optical path is not the main optical path of the imager, and calibration is required, resu...
