Structure from Motion - Target aisles

Went to Target and shot a couple of videos using my iphone 4 to test Structure from Motion 10 (SfM10). The iphone 4 captures videos at a resolution of 1920x1080. To extract the frames from the videos, I used avidemux. Two mega pixels per frame is not too bad for SfM10, so I didn't downsize the frames.

Input to SfM10: 4 frames at a resolution of 1920x1080 using a focal length equal to 1920x35/36=1866 (number of trials in AC-RANSAC = 1000, max number of iterations in Bundle Adjustment = 1000, and min separation angle = 0.0).

Input to SfM10: 5 frames at a resolution of 1920x1080 using a focal length equal to 1920x35/36=1866 (number of trials in AC-RANSAC = 1000, max number of iterations in Bundle Adjustment = 1000, and min separation angle = 1.5).
