Enhancing 3D Scanning with Photogrammetry

In: 3D Hardware| 3D Scanning Projects| Metrology and Inspection
29 Nov 2011It was to be expected that we would talk a lot about photogrammetry after we’ve launched the MaxSHOT 3D optical coordinates measuring system. But it’s OK, since what we have to say is interesting!
Product manager Dan Brown wrote a new column published on Quality Digest Online explaining how to enhance 3D scanning with photogrammetry…Here’s a sneak peak:
“Improvements to the intrinsic parameters of a system are limited to the technology itself, and there is only so much that can be done with that. On the other hand, there are some ways to improve the accuracy of the positioning device and ultimately lower the error rate of the global 3-D measurement.”

quisiera saber en que formato esta la geometría, y cual es la posibilidad de pasarlo al formato CAD? estoy trabajando con un simulador físico llamado comsol y necesito trabajar con geometrías compatibles.
