Alex, you can try Agisoft Photoscan. The academic licence is not prohibitively expensive.
We have recently published a combined methodology to obtain reliable structural data from high-resolution virtual outcrops generated from handheld cameras.
Building a virtual outcrop, extracting geological information from it, and sharing the results in Google Earth via OpenPlot and Photoscan: An example from the Khaviz Anticline (Iran)

Asunto: Re: Cliff face photos in 3D space
Dear Alex
As part of my PhD I'm using oblique photogrammetry to produce 3D models for structural interpretation. I've recently published a paper on the workflow I'm using :
Svennevig, K., Guarnieri, P., and Stemmerik, L., 2015, From oblique photogrammetry to a 3D model – Structural modeling of Kilen, eastern North Greenland: Computers & Geosciences, v. 83, p. 120–126, doi: 10.1016/j.cageo.2015.07.008.
In short I use a photogrammetry software to triangulate and georeference oblique photos, then digitize geological features and import this into Move where I construct the 3D model.
If you don’t have access to the more advanced software for photogrammetry like SocetSet you could try using Agisoft.
This of course requires that you have taken your photos with some overlap (min 60%)
Cheers
Kristian

Subject: Cliff face photos in 3D space
Dear all,
I’m currently working on a 3D geological model of an open pit located in a polydeformed metamorphic terrain and I would like to import and georeference cliff face photos in 3D space. The photos have control points in X,Y and Z. Does anybody have experience on how to proceed for doing this? I would preferentially like to use the Surpac, Move or GeoModeller softwares, but, perhaps there is a better choice?
Thank you for your help,
