Photogrammetry image overlap
WebJun 4, 1994 · Higher image overlaps and coarser GSDs have a clearly positive influence on reconstruction quality. Therefore, higher accuracy requirements in the GSD must be compensated by a higher image overlap. The best results are achieved with an image overlap of >: 95% and a resolution of >: 5 cm. WebSep 10, 2024 · Videos are essentially a sequence of images, and therefore can provide a good set of overlapping images for the photogrammetry software. However, there are …
