COLMAP export to CMVS-PMVS2

[Abraham]

Hello,

I am following your instructions to export the model for CMVS-PMVS2 use and I am getting the error below when running the step "

sh /path/to/undistortion/folder/pmvs/pmvs.sh" from (https://colmap.github.io/tutorial.html#dense-reconstruction).

The error is:

"Unrecognizable option: "

Any ideas about what could it be?

[Johannes Schönberger]

pmvs2 needs to be in your system path for this to work. Is this the case?

@Abrahan u can try 

1. Right-click on the My Computer icon on the right side of the Start Menu.
2. Click “Properties” from the context menu.
3. Click “Advanced system settings”
4. Go to the “Advanced” tab
5. Click “Environment Variables…”
6. Click variable called “Path” and click “Edit…”
7. Add the path to the folder containing pmvs2 to the end of the value in your PATH variable adding before ;

I already have the the path for the (pmvs2. cmvs and genOption) binaries in my system variable PATH. If I type pmvs2 in console I see the message below. However, when I add the prefix and option-file it outputs: "Unrecognizable option: "


Usage: pmvs2 prefix option_file

Found the problem. It is silly. The path has to end with a slash.

Not working: pmvs2 path/to/pmvs/folder option-0000
Working: pmvs2 path/to/pmvs/folder/ option-0000

Thank you all!

This is explicitly mentioned in the tutorial and it is an annoying "feature" of PMVS :-)

One of the trailing slashes probably should be removed (did not work for me with it)

Hi all,
have you managed to perform the dense reconstruction? 
I tried to run CMVS as well as PMVS-2 and it does not work for me, have a look. What do you think?

./cmvs/program/main/pmvs2 Undistortion-PMVS/pmvs/ option-all

tflag is not valid: 0

./cmvs/program/main/cmvs Undistortion-PMVS/pmvs/ option-all

I've just checked all the requirements to pmvs input (http://www.di.ens.fr/pmvs/documentation.html),

it does not look like COLMAP has an output that can be used as pmvs input.  Has anybody done it?
