I’ve been playing with “structure from motion” / “photogrammetry” apps for a bit. Lots of stuff still to figure out, but here’s a possible interesting path. Note that none of this is optimal – wrong camera, wrong print medium, etc – but its fun.
1. Start with a Video of walking around The Dude Abiding.
(His name is Joel, he’s one of my coworkers, he also teaches kids how to code)
2. Using VLC, play then Shift-S to snap, then plan, then Shift-S to snap, to extract a bunch of frames.
4. Crop in the model box, hit Build Dense Cloud. This is where it starts to look really interesting.
5. Build a Model .. Build Texture. This is what the result looks like at “medium” resolution:
Not the greatest, but that’s because of the camera I used (video compression = artifacting = bumps) plus camera lens distortion etc.
6. However, that doesn’t work for what we’re doing next. I don’t own a $10k color 3d printer. So instead.. paper!
Build a model at lower resolutions:
Don’t forget to close holes! (tools menu) … build texture…
7. Export the model. This is the $179 pay for step in Agisoft PhotoScan.
Note that this saves both a .JPG and a .PNG texture. JPG on the Left. I might be mistaken, but I think they were saved at the same time. Actually, the .JPG might be the overall “build me a texture”, and the .PNG is the “export my model to wavefront”. It’s a little freaky.
8. Load the .OBJ into Pepakura. $39, I totally plan to buy it.
9. Unfold, and Print:
10. Print it out on cardstock, cut, and fold ..
I haven’t done this part yet.
These screenshots were from my second attempt. Here is Joel holding my first attempt, which was 500 faces, a bit too complex:
