open source close range photogrammetry

[Chris Erskine]

Hi,

I'm looking for a something to do close range photogrammetry. in at least a semi-automated way.

I have image modeller (formally realviz) thanks to an autodesk subscription. but I'm finding this really hasn't moved much in years compared to the software for stitching 360 panos (i must admit i use ptgui by i have been following hugin for a few years now). now its seems like there a lot of hugin that could transfer over to photogrammetry. esp the automated control point detection. or a semi automated where after the camera views had been calibrated you could pick control points in one view and it gets added to the other views.

I guess it would mean changing from a single point in space to a real 3d workspace. but it seems to me that a pano stitcher could be intergrated with photogrammetry and they would both work really well together. and that would also mean mosics would work really well too.  

anyway I'm not a programmer and I'm sure this is quite a lot of work. so if you know any other open source software out there that can do this I'd be really interested.

it just seems like all the commerical software for this isn't really going anywhere.

Hullo Chris,

I suspect that this <http://stereo.sourceforge.net/> isn't going to
do what you really want, but may be useful in some respects.
I would like to see this concept taken further with tools for adding
control points similar to those in Hugin.
I think a lot of what is needed to incorporate a stereo capability
into Hugin is in the PTStereo source, which hasn't been released.

cheers, I hadn't seen this before.

there is some stereo open source code in opencv...

anyways here are some nice links for the hugin developers and for whomever started the thread:

From the links that have been suggested so far, I doubt people have a
good idea of what's actually needed. As an example, I'm involved with
a project documenting prehistoric rock carvings. We need to produce
dense 3D meshes with sub-millimetre accuracy across surfaces of a few
square metres in the field, for archival purposes, to distinguish
artificial markings from natural, to analyse tool marks etc. There is
commercial software, but licences of even just a couple of hundred
pounds are way out of affordability, and as I'm running the rest of
the project on free software (Quantum GIS, Hugin panos for landscape
context, etc) this is a real pain.

There's a huge gap between the existence of some library routines in
NASA Vision Workbench, or OpenCV, and an application that can be
deployed to do useful work. One typical attempt was Oxford
Archaeology -- https://launchpad.net/stereophoto -- but unfortunately,
in the usual manner, it got nowhere beyond a single small code dump
some years ago. Many of the projects that do exist (Stereo, jSVR
http://svr.sourceforge.net/, the voxel stuff) just aren't usable for
general purposes. If I were thirty years younger, I'd tackle it
myself :-(

Where can one join? The website only gived the mail address of the
author.

Also, did anybody get this to run? I managed to compile it on Linux
after some tinkering, but only got a segfault after trying to match
images.

that insight3d looks amazing.

I'm going to have a look at this.
