This is one of three test models of the same subject (vase) using three different cameras (Canon Powershot A640, Canon EOS 1DS MKIII and Konica Minolta Dynax 5D).

It is an attempt to see how Photosynth processes different size imagery and whether size affects the end point cloud. This particular model is produced with imagery from the Canon EOS 1DS MkIII at F22, 1 metre focal distance.

What were your findings? Did the photo resolution make a difference?

Hello HenleyB,

To my eye the 1DS produced a slightly denser, more accurate point cloud than the others, but the difference between this and the 10mp A640 model looks to be minimal. The Dynax 5D model was poorest of the bunch with elements of distortion all over.

Due to the resolution and the presumption that Photosynth would be able to pick out more common points across the imagery, I was expecting the 1DS model to have a significantly denser point cloud.

The results were interesting, but I think I need to try a few more similar experiments on different subjects to come to any firm conclusion.
