Nghiaho optimizations are disabled by default as I’ve found that it generates a point cloud less dense. You can enable the optimization by adding:

--optimize

as last PMVS2.exe parameter in your command prompt or just activate the optimization by modifying the following files:

• 3 – Prepare for PMVS2.wsf line 49 -> var USE_OPTIMIZED_PMVS = true;
• 4 – Prepare for CMVS.wsf line 46 -> var USE_OPTIMIZED_PMVS = true;

You can download PhotoSynthToolkit11.zip.

• CMVS support finally integrated
• proper handling of folder with white space

How to use CMVS with PhotoSynthToolkit:

1. As usual run step 1 and move pictures from “hd” to “distort” folder.
2. You need to run first “Prepare for PMVS2″ then do NOT launch the generated bat file.
3. You can run “Prepare for CMVS” and run the generated bat file.

Warning: I’ve fixed all my programs to handle folder with white space (thanks to boost::filesystem). Sadly PMVS2/CMVS don’t handle them. The fix is trivial but instead of recompiling a new version I’ve found a bad workaround. I’m creating a temporary virtual drive z: pointing to your synth folder during the execution of PMVS2/CMVS using SUBST. The downside are that if you already have a z: drive it won’t work and if you kill PMVS2/CMVS you’ll have to manually remove the z: drive. To remove the z: drive type “subst z: /d” in your console.

If you need XSI/3DS max integration you’ll have to use the old version: PhotoSynthToolkit7.zip otherwise PhotoSynthToolkit9.zip is the latest version.

Download location and source code introduced in my previous post.

I have updated my PhotoSynth toolkit for easier usage (the same way as SFMToolkit). This is an example of dense mesh creation from 12 pictures using this toolkit:

The 12 pictures were shot with a Canon PowerShot A700:

Thanks to this toolkit, PMVS2 and MeshLab you can create a dense mesh from these 12 pictures:

triangulated mesh with vertex color -> triangulated mesh with vertex color and SSAO -> triangulated mesh shaded with SSAO -> triangulated mesh wireframe -> photosynth sparse point cloud
(sparse point cloud : 8600 vertices, dense point cloud: 417k vertices, mesh: 917k triangles)

You can also take a loot at the PhotoSynth reconstruction of the sculpture.

PhotoSynthToolkit is composed of several programs:

• PhotoSynthDownloader: download PhotoSynth point cloud and cameras parameters
• PhotoSynth2PMVS: enable to run PMVS2 with a downloaded PhotoSynth point cloud
• PMVS2 : http://grail.cs.washington.edu/software/pmvs/ created by Yasutaka Furukawa
• PhotoSynthViewer: Ogre3D PhotoSynth viewer [not working yet]

Download

The source code is available under MIT license on my github. I have also released a win32 binary version with windows scripting (WSH) for easier usage: PhotoSynthToolkit4.zip.

Help

If you need some help or just want to discuss about photogrammetry, please join the photogrammetry forum created by Olafur Haraldsson. You may also be interested by Josh Harle’s video tutorials, they are partially out-dated due to the new PhotoSynthToolkit version but these videos are very good to learn how to use MeshLab.

Please go to the PhotoSynthToolkit page to get the latest version

I’ve finally managed to spend a couple of hours to compile a 64 bit version of PMVS2 for windows! You can download PMVS2_x64.zip right now. I’ll hope that this version will help some persons, I’ve personally managed to create a very dense model thanks to this version and PMVS2 was using more than 4Gb of ram on a 8-cores machines.

How to compile PMVS2 x64 by yourself:
download the CMake package of CMVS (containing PMVS) created by Pierre Moulon.
download and compile gsl 1.8
download precompiled pthread x64 lib from equalizer svn
download and compile clapack 3.2.1 using CMake

PhotoSynthTileDownloader

As requested by some persons, I’ve updated my PhotoSynthTileDownloader: you can now resume a partial download ! It’s already available for download: PhotoSynthTileDownloader2.zip.

Videos tutorials

Josh Harle has done some very nice videos tutorials on how to use my PhotoSynth ToolKit and has created another toolkit for Bundler that is using my BundlerMatcher.

Note: In fact your synths doesn’t need to be 100% synthy. My tool (PhotoSynth2PMVS) is capable of using an uncomplete synth. And now you could use my 64bit version of PMVS2 instead.
