NeRF in the Wild: reconstructing 3D scenes from internet photography

can you elaborate on the key variables for the data? for instance, is it safe to assume 360 photos from the same angle would yield a worse model than 1 photo from 360 different angles?

what does the ideal minimal data set look like (eg, 5 photos from each 15-degree offset)?

thanks for being so active on this thread.

NeRF's (and all of photogrammetry's) bread and butter is 3D consistency -- that is, seeing the same object from multiple angles. A 360 degree photo from a fixed position just won't do. As to how to select the best camera angles...I'm not sure. I believe there is research in this area for classical photogrammetry techniques, but I'm not familiar enough to point you to a body of work.
