Am I doing something wrong?
Hi!
Complete amateur here, looking for some specific advice on modeling a small room. I mentioned it in this older post: Exif data not being used?
I want the room modeled for fun! I have an Oculus Rift so it would be awesome to walk inside it. It's also a restricted room, so an idea is to avoid cramming people into it and just introduce people to the VR version instead. Additional fun can be had by adding audio recordings, smoke and lighting effects (ugh, how to add realistic lighting to a prelit scene?).
I will read a lot more in this forum and follow the advice of Wishgranter to add more and more photos rather than taking them in all at once. I finally have a license for RealityCapture so I don't have to be afraid anymore that a number of grinding work hours would be lost :p
Please see these youtube videos for an overview of the scene, I recommend watching the output video first: https://www.youtube.com/playlist?list=P ... QQMj2RzKHI
Thank you for any pointers!

Your reconstruction is not so bad, given the fact that the subject is not that easy : glossy pipes, not so much textures on the materials. We can see in your video that the highly textured objects are better reconstructed than the poorly textured ones.
I would recommend the following things :
-Take a few (as much as you can actually) pictures on a tripod with minimum ISO and maximum depth of field (closed aperture). This will lead to long exposure time and that is why you need a tripod. Pay attention to the focus, your image need to be razor sharp so RC has a lot of useful features to look for.
-Take pictures with a shorter focal length. Overlap overlap overlap ! -
And then you will have to tweak and play with the alignment settings : lens distorsion model, detector sensitivity, overlap, max reprojection error, ...
One last thing, you mention a delit process on your input pictures ? I don't think that is a good thing, maybe you better leave your pictures as they come out of your camera and let RC do the job. -

Thanks for this! I did use a high ISO to get these pictures without using a tripod, so I gathered a lot of noise obviously. I avoid using a tripod for the simple reason that the room is very cramped so it would limit the possible angles I could take pictures from, and because it would take more time. But... I might be overestimating how many pictures I actually need. Maybe fewer higher quality pictures will go a long way. -
I agree, the results are not bad.
The metal foil clad pipes are simply the worst case.
Try to cover them with something or at least put stickers on them to help RC find features.
Other than that, you just need to experiment and see what works for you!
About your question concerning exif data:
What your camera or lens tells you is only a rough guideline.
If everything is in order with the images, then RC will calculate the actual values very precisely.
And those can differ quite a bit from the ones in the tech specs...
