Photogrammetry
Photogrammetry yi awọn aworan agbekọja lasan si awọn awoṣe 3D deede, awọn maapu, ati awọn wiwọn.

It matters because it lets anyone reconstruct real-world geometry at scale using just a camera, from drone surveys to digitizing museum artifacts.

What is Photogrammetry?
Photogrammetry yi awọn aworan agbekọja lasan si awọn awoṣe 3D deede, awọn maapu, ati awọn wiwọn. O ṣe pataki nitori pe o jẹ ki ẹnikẹni tun ṣe geometry gidi-aye ni iwọn lilo kamẹra kan, lati awọn iwadii drone si digitizing awọn ohun-ọṣọ musiọmu.
Kini ibeere akọkọ ti awọn fọto igbewọle fun fọtoyiya lati ṣiṣẹ?
Photogrammetry triangulates 3D ojuami nipa ibaamu kanna awọn ẹya ara ẹrọ kọja awọn fọto ti o ya lati ọpọ wiwo, ki idaran ti ni lqkan ati angula orisirisi jẹ pataki.
