Images (acquired by both UAV types) grouped by inclination. This classification is based on the wing type of the UAV (Rotary-Wing UAV” and “FixedWing UAV). Images with different characteristics were used to produce mosaics from the algorithms. The first performance preferred a flight height of 30 m (Ground Sample Distance, 0.82 cm/pixel) with the frontal overlap of 80%, and the second performance preferred a flight height of 60 m (GSD, 1.64 cm/pixel) and same overlap. Ten images from both performances were combined in all algorithms. Mismatches have been observed, and the mosaics produced after a very long process are not found satisfactory. According to the results, for rotary-wing UAV (SURF, BRISK and FAST), the algorithm run times were determined as 76.5 minutes, 11 minutes and 1839 minutes. Also, for fixed-wing UAV (SURF, BRISK and FAST), algorithm run times of 238 minutes, 95 minutes and 3350 minutes were determined.Elektronikeninfo:eu-repo/semantics/openAccessBRISKMühendislik Temel Alanı->Yer Bilimleri ve MühendisliğiFASTImage mosaicingSURFUAVArticle
