Photogrammetry Scans a Kiwi with a Lower-Spec Camera Than Usual Photographing and scanning the kiwi, a flightless bird native to New Zealand, was done using a camera with lower specifications than my usual D800 DSLR. A metal model was scanned with the Nikon Coolpix W300. Sixty-seven photos were taken at 1600x1200 resolution, ISO 125, and an average shutter speed of 100 milliseconds. The focal length was set to 24mm / f2.8. The photos were then processed into a photogrammetry scan, which successfully aligned all sixty-seven images. The highest accuracy setting with a tie point limit of 4000 and key point limit of 40,000 resulted in 35,630 tie-in points. A depth map was created using ultra-high quality and moderate filtering mode (1 minute 56 seconds). A dense cloud was created, resulting in 670,205 points (5 minutes 22 seconds). The final 3D model had 180,000 faces and took 1 minute 51 seconds to create. This 3D model was then printed on the FlashForge Guider II S at high resolution using white 1.75mm PLA. It took six hours and thirty-eight minutes to print, with a raft and linear supports used in the process.
