Re: Photogrametry algorithms (3D from 2D images)



You can reconstruct a 3D mesh from 2D images using reconstruction
algorithms in IDL.

1. Create an ROI group object.
2. Define individual ROIs using reference points in each image.
3. Specify a z dimension for each image using distance information.
3. Use
result = oROIGroup->CompteMesh(vertices, connectivity)
to obtain connectivity and vertices for the 3 D reconstructed model. It
creates a mesh
using triangulation. You can redefine the mesh object by conoverting it
to a tetrahedral mesh, which I think preserves overall topology better.

Hope this helps. Its just a few lines of code, but seems to do the job!
