Use Space Carving to Initalize Mesh
« on: December 31, 2015, 09:40:41 PM »
Ok....we already did all the work to place markers on our photos for alignment.... and masked out the "uninteresting" parts of the images.... Why not use those mask boundaries to build an initial mesh of the surface using a space carving algorithm? Then you could refine the initial mesh using the methods already implemented in PhotoScan?  (see "A Theory of Shape by Space Carving" by KIRIAKOS N. KUTULAKOS and STEVEN M. SEITZ)

Can you point me to a reference describing the algorithms details or Computer vision libraries used in Photoscan?  Do you have any guidance as to how I should go about implementing this Space Carving idea using your python script interface in PhotoScan?  I am especially concerned about accessing the mask data and providing the initial mesh to the rest of the PhotoScan workflow.
