@Pablo: I'm well aware of the current PhotoSynthToolkit limitation... this is why I've updated my PhotoSynth Viewer. I'm willing to add the possibility to create cluster manually (thus without CMVS) from the viewer. So this should allow very dense reconstruction without the fear to run out of memory in the PMVS2 stage!

Using the Photosynth + PMVS I gest fantastic ressults, but when in photosynth lots of points have been detected during PMVS my 8gb of ram are totalled and the process stalls and crashes… As read from Furukawas page the CMVS should split the project into a manageable size so I tried your BundlerMatcher procedure but it only uses one core and takes a loooog time when I do launch Sparse point cloud bat.
As read before, I also think that would rock that photosynth stuff could be “transform” so that we can use the CMVS+PMVS.
Or any similar process that does not kill our Pc’s.
WHat I love from photosynth is the queue, so we can leave the pc computing while we’re outside, sleeping, at class… whatever. Would rock a queue for the .bats generated for the PMVS process too.

Hi. I was running Toolkit5. Now it is working!!!. I think that it was a matter of path name. I do now download the synth directly to a drive with a folder named with a single letter. I download the synths to folders named “a” “b” “c” and later i do rename then and prepare for PMVS with no problems. Thanks.

@Pablo: Downloading a synth may take a while if you download thumbs too, have you checked the thumbs folder? Are you using PhotoSynthToolkit v5? Is the program crashing? I need more information to be able to help you…

Hi. I’ve used the photosynth workflow till the end with succes. Impresive point density!!.
Now I’m having problems at the first step as the thumbs are not downloading even if I do check in the prompt window that yew I want them to be downloaded. I’ve tested this with several synths and problem keeps going. Unziped again the toolkit and same problem. Downloaded teh synth sfuff in different hd drives sand problem keeps equal… any suggestion? If I use the tile downloader and put the tiles in teh thumbs folder should work?? I’ll try anyway to see what happens. But wanted to comment that error-problem.

@marty: if you are using my toolkits (photosynth or SFM) they are configured with good default values. You can change these values if you understood PMVS documentation, otherwise you can take a look at the photogrammetry forum.

hello
I have 2 questions about the very good tutorial of josh Harles toward photosynth toolkit.
First I constat that the pmvs application exist in the photosynthtoolkit 3, so it’s not necessary to download pmvs2 and put the pmvs2 application + pthread.dll in the folder of photosynthtoolkit 3, That’s thrue??

another remarque are they a difference between pthread.dll and pthreadVC2.dll wish is in the photosynthtoolkit 3. Does we erase pthreadVC2.dl and replace by pthread.dll or it’s not necessary??

At last, my third remarque: we can constat that in the folder of photosynthtoolkit 3 of Josh Harle they are DLL like libANN.char.dll and ann_1_1.char.dll and zlib1.dll that doesn’t exist in photosynthtoolkit 3. why? , is it necessary to put them or not?

Thanks for your answer
