I used the comparison article on wikipedia to choose 3 free to use cloud based photogrammetry services.
Note: arc3d requires a desktop application to to pre-process and upload the pictures. The application is available for xp, vista, windows7, Mac os10.7 and linux source code. I could not get the source code to compile, the xp and vista applications did not work, but the win7 did. I did not try on a Mac. The software has obviously not been upgraded for a while.
I uploaded the same set of 50 pictures to each service. The pictures were taken outdoors with a hand held Panasonic camera set on manual to 100 iso and 10 megapixel resolution.
arc3d.be responded after 2 hours with an error message suggesting I contact “the developers”, no response from phov.eu after 36 hours, autodesk recap processed the 50 pictures in less than 2 hours and supplied the results as a downloadable obj file and rcm file. RCM is the Recap mesh and OBJ is a universal 3D model format. This shows that it was possible to process the 50 pictures using a cloud based service. Unfortunately, Autodesk intend to start charging for the service by subscription in December.
Also tried this with no luck. (not listed on the wiki.) http://app.selva3d.com/transform
Here are screen captures from the recap web interface:

Another way, once recap is no longer free.
