Another test of 3d reconstruction, this is from Otternes farm in Flåm, Norway.
tried to capture some details just to test how it worked out.
First set reconstructed quite well
This one I should have taken some more images, but it still worked out accurate cordinates
Welcome! This blog will mostly be a mix of photo, 3d graphic and realtime programming. enjoy!

Dense 3d point cloud reconstruction of mountainside
Testing large scale point cloud reconstruction of a mountainside.
This area was about 150-200m wide, reconstruction makes it possible to do a detailed inspection of the mountainside topography.
Used a set of 13 images on this one and imageresolution of 2144 pix wide. 430 000 vertices.

Dense 3d point cloud reconstruction
Done some testing on dense point cloud 3d reconstruction using the free Bundler .
This is the most robust reconstruction software I have tried so far, and its free:)
Example below successfully reconstructed all visible sides of the object, missing some areas on object that has no detail to track. the fabric the matchbox is lying on is completely reconstructed with no artifacts at all. total verts is about 90 000.
Some notes:
-Camera used Nikon D300, shot at lowest resolution and Fstop 11.

Some notes:
-Camera used Nikon D300, shot at lowest resolution and Fstop 11.
-Had to add camera to the DB using --checkCameraDatabase and then specifying censor width.
-More images is better, tried with half number of images and result lacked some details.
-calculation time about 15min (i7 920).
-number of vertices gennerated, about 90 000.
