METHOD OF FORMING CATALOG OF CELESTIAL OBJECTS OF LARGE ARRAYS OF ASTRONOMIC IMAGES Russian patent published in 2018 - IPC G06F17/30 

FIELD: astronomy.

SUBSTANCE: invention relates to the formation of a system for storing, processing and intellectual analysis of large data sets of astronomical observations. Method of forming electronic catalog of celestial objects of astronomical images large arrays is disclosed, which includes the following steps: a) determination of the target image of the sky, followed by its splitting into rectangular cells of equal area, containing images of parts of the target fragment of the sky in the specified cartographic projections, while the cell sizes and the overlap, the type and parameters of the cartographic projection for each cell are pre-defined as input parameters, and upon partitioning each cell is assigned a unique identifier, representing the coordinate of the cell in the target fragment of the sky; b) obtaining primary observations that represent an array of unprocessed astronomical images and their calibrations; saving them in a distributed file system; c) processing of an array of astronomical images using the mapping-convolution model; e) formation of a catalog of celestial objects of the target fragment of the sky by detecting celestial objects on the final images, removing artifacts and measuring the values of the attributes of celestial objects, with the assignment of coordinates to the detected celestial object and a unique identifier using the Mapping step; e) saving generated catalog containing the values of the attributes of celestial objects in the distributed file system, in a columnar format that allows statistical processing of a large number of attributes of celestial objects using the Mapping-Convolution model; the steps a)–e) are repeated many times for each target fragment of the sky and each spectral range, after which the cross-identification of celestial objects in the generated catalogs is performed using the step of Convolution and the formation of a master catalog, containing for each celestial object a combined list of attribute values from different catalogs generated in step e) for the target sky fragments and spectral ranges or derived from external sources.

EFFECT: technical result is to ensure the possibility of increasing the efficiency of statistical processing, as well as incremental processing of data.
