Photogrammetry on the cheap
show user profile  Nik Clark
I've just discovered photogrammetry on the cheap (free) using MeshLab, VisualFSM and CMVS. Much fun.

Damn Nik that looks pretty damn good.. I've been dying to try out something like this..

Looking at the videos on the CMVS and VisualSFM pages, it's pretty incredible, almost a glimpse at what could be possible in terms of generating virtual representations of actual places and things from an arbitrary bunch of photographs.. Imaging going to a location with a large resolution camera and offloading it onto a gpu farm..

You mean "on the sheep"

Just wait until STRAT (or Grotey for that matter) learn about this.

Holy sheep. That's awesome. Did you use all three mentioned softwares, Nik?

Yeah, it seems to work quite well when it works.

I took 44 photographs of it with my phone, used VisualFSM for the sifting and setup, then CMVS for the high detail scan to make the point cloud. I then used Meshlab to remesh the point-cloud, render the texture and optimise the mesh. It took a while to figure it all out, but I'm impressed with what you can get from a few snaps with your phone.

ScotlandDave, yeah, I really want to try some open stuff, indoor large buildings, etc. The possibilities seem endless.

If you want to try it, here's what you need:

VisualSFM:http://ccwu.me/vsfm/
CMVS:http://github.com/pmoulon/CMVS-PMVS
MeshLab:http://sourceforge.net/projects/meshlab/?source=typ_redirect

Here's the basic instructions for VisualSFM:http://ccwu.me/vsfm/doc.html#usage

When you've done this, it will look like crap. Don't worry, MeshLab fixes that.

In Meshlab,Open the project CMVS saved, Import the PLY mesh. Show the cameras and do a Poisson surface reconstruction, then "Parameterization and texturing from registered rasters" to make the texture. After that, you can use Quadratic edge collapse decimation (with textures) to simplify the mesh. Export and BAM, a 3D scan on the sheep, er, cheap.

Amazing Nik thanks, def going to give this a bash..

[edit]

Poisson surface reconstruction, parameterization from registered rastered, quadratic edge collaps decimation - sounds like a walk in the park..

Ever looked inside a sheep? Me neither... till today...


P.S. Good shit, Nik. It's pretty solid. Sure, it's all broken textures if you zoom way in, but it's still pretty darn good.
