3D printing and digital 3D replication technologies have existed for nearly a decade and been used in a complementary fashion for a variety of professional and industrial applications, such as reverse engineering and digital archiving. Yet it’s only been in the last few years that we’ve seen a growth in these technologies used together for cultural & archeological replication, stop motion animation and scenery development, surgery and prostheses development and service bureaus producing consumer keepsakes, all of which rely on the combination of digital image and geometry replication using 3D scanning or photogrammetry and 3D printing to produce physical 3D human and animal forms.
According to Photogrammetry.com, photogrammetry is the science of making precise measurements from photographs. The output produced from photogrammetry can be, among other things, 3D models of real subjects, including people and animals.
To digitally replicate human and animal forms using photogrammetry, multi-camera systems are precisely placed in a photogrammetry room or studio. The digital 3D image of the subject is achieved instantly using hundreds of photos taken from different angles, typically using SLR (single-lens reflex) cameras placed in the specially lit space. The geometry, or the form, of the subject is then calculated separately in software, such as AGISoft.
Photogrammetry enables instantaneous data capture, which is enormously beneficial in digital 3D body form capture. Instant data capture means that even if the subject moves ever so slightly, it does not affect the resulting 3D data capture and therefore the appearance of the subsequent 3D printed figure.
