Best lens for photogrammetry 3d scanner setup?
Hello all, I plan to use my Panasonic LUMIX G85 (micro 4/3) with a 3D scanner setup. This will be fairly close photography, with the max object size being in the 24in(61cm) range.
I have a basic telephoto and nifty fifty, but wasn't sure if there was something better suited for my purpose.
If it makes any difference, I was planning on using a vertical line laser in a black box to take the pictures. I'm assuming there's a filter that can help.
I know this question requires rather specialized knowledge, but if anyone has that knowledge, it's Lemmy.
No super specialized knowledge here, but I have gone through my share of photography equipment reviews.
Things to look out for:
- Lens distortion. The most common are barrel and pincushion, but there are some others
- A flat focal plane
Neither of those is necessary a show stopper, but you need to be aware of how much your gear exhibits this behavior and work around it according (eg correcting for lens distortion before processing, not relying on the whole width/height of the sensor if necessary, etc).
Hmm, I think Panasonic has software that can correct for some of that based on the lens initially used (it's been forever since I played with it, though).
Thank you for your help!
There are tons of software options to correct for distortion, just be sure to process the files before you use them if your lens has significant distortion. Also note that zooms exhibit different amounts and types of distortion at different focal lengths.
Good luck! Keep us posted with results!
