An coronagraph optical system and method for continuously imaging a wide field of view that includes the Sun. Examples of the coronagraph optical system include an all-reflective foreoptics assembly that receives light rays from a viewed scene and a direct solar image of the Sun, a sensor assembly configured to produce an image of the viewed scene, an all-reflective relay optics assembly configured to receive the light rays from the foreoptics assembly and to reflect the light rays to the sensor assembly, and a solar rejection optical component positioned between the foreoptics assembly and the relay optics assembly and dynamically configurable such that the direct solar image of the Sun is reflected away from the relay optics assembly and the light rays are reflected to the relay optics assembly while an entrance aperture of the foreoptics assembly is continuously positioned towards the Sun.

The invention relates to a method for describing sunspot groups in a full sun image, belonging to the fields of computer vision and natural language processing. In the present invention, by making a data set of sunspot group images and description texts, the original images are first sent into the improved VGG-16 network to generate feature maps, and then the output feature maps are sent to the positioning layer, which is generated by the improved Inception-RPN Candidate regions are finally processed into fixed-size region features, which are processed into one-dimensional vectors that can be processed by LSTM after passing through the recognition network, and finally generate description sentences; compared with traditional methods, the present invention can obtain more accurate Candidate regions, which improve the description quality of the entire network.

The invention relates to a multi-scale velocity field measurement method for adjacent two frames in a sun high-resolution image sequence and belongs to the astronomical and image technical field. The method comprises the following steps: to begin with, carrying out image pretreatment: expanding image boundary of the adjacent two frames; then, decomposing the two frames into two frame pyramid images; next, carrying out segmentation on the two frame pyramid images layer by layer; measuring block displacement between the two frames; obtaining point-by-point displacement amount between the two frames through weighted smoothing and interpolating calculation; then, superposing the displacement amount between the two frames of all layers of the images; and finally, obtaining comprehensive displacement amount and velocity field between the two frames. The method can calculate the velocity field between the two frames more accurately, and effectively improves measurement precision of the velocity field.
