Issues about the reconstruction of the scene using VisualSFM #19

Open onion-liu opened 7 years ago

onion-liu commented 7 years ago

Hi, Alex, I try to use VisualSFM to reconstruct the model of the scene with the "KingsCollege" pictures. But the result is not good, especially the "focal length" in ".nvm" file, and it ranges from 800 to about 7000, not 1668 as your "reconstruction.nvm" shows. Did you use special configuration with VisualSFM? Thanks for your time.

Hi liu, Have you figure out the reason of the problem? I'm working on it now and I met the same problem. Thx.

@Chen0403 Hi, Chen, I find that there is an option at SfM->More Functions->Use Shared Calibration, and the result seems better. But I don't know whether it is the right way.

@onion-liu Thanks! I will try it.

Hi Alex, Hi Liu and Chen, I'm not experienced with 3d reconstruction things, but it seems strange to me that the Z coordinates vary too much, e.g., in KingsCollege it's -2.738007 ~ 3.122726, in StMarysChurch -18.054653 ~ 58.878734. Is there any possible explanation?
