I'm currently exploring the application of my single-image photoclinometric 3D reconstruction algorithm to generate DEMs for various areas of interest, in particular where we have no other (i.e stereo-imaging based) detailed 3D reconstructions yet.
One of the first areas I have always wanted to visit "from the ground" is the famous Dust Avalanche caught live in action by HiRISE. Follow this link for a small web gallery with color 3D renderings of a DEM derived from the originally published HiRISE image, rendered under various viewing positions and light source directions. The original 2D image can be found at the HiRISE site under the observation ID PSP_007338_2640 Disclaimer: The single-image derived 3D DEMs are mainly intended for visualization purposes. Although they are quite exact at reproducing relative heights at small scales, they are less accurate with respect to absolute heights at large scales. |
