subject

Datorzinātne histogrammu saskaņošana Sentinel-2 mākoņu detektēšana ĢIS attēlu apvienošana

description

Jauni satelītu attēli ir praksē noderīgi, tos izmanto dažādās jomās, piemēram, kartogrāfijā. Šajā darbā tiek apskatīti Copernicus Sentinel-2 satelītu uzņemtie Zemes attēli. Tiek izpētīta satelītu programma, rīki un datu formāti. Tiek apskatīti lēmuma koku un Beijesa klasificēšanas algoritmi, kas ļauj izgūt mākoņus un citus reģionus no attēliem, izpētīti attēlu apstrādes algoritmi, kas ļauj saskaņot dažādu attēlu vizuālo izskatu pēc attēla histogrammas datiem. Darba praktiskajā daļā tiek realizēta sistēma, kas ļauj izgūt lietotājam aktuālāko satelīta attēlu noklājumu pār ģeogrāfisku intereses reģionu. Attēli tiek veidoti kombinējot jaunākos satelīta uzņemtos datus kopā tā, lai gala attēlos nebūtu mākoņi. Tiek parādīti risinājumi kā ģenerētos attēlus pēc tam ir iespējams publicēt citos ĢIS risinājumos, kurus tālāk izmanto gala lietotāji.
