Using a SIFT pipeline for photogrammettry, I have successfully recreated small objects, Comet 67P and some buildings from quadcopter pics. First I search for features with DoG and match them with SIFT , do a bit extra crawling along matched edges and the result is a dense coloured point cloud. The point clouds are converted to a mesh with poisson surface reconstruction and retextured with fragments of the original images. The Poisson surfaces are never quite as nice as the point clouds - I am using Meshlab for this part. Processing a few hundred big images takes ages so I send the jobs up to EC2 for a few hours so each job is usually a couple dollars. It is pretty useful as a 3D scanner.
