Hi, I have just started using OTB 5.8.0 on ubuntu 16.04 LTS. I am exercising examples in the cook book. But, now I am stuck with otbcli_StereoRectificationGridGenerator.
I am running the grid generator with -epi.step 1 (which is default value) on a world view 2 pan image as: otbcli_StereoRectificationGridGenerator -io.inleft image1.tif -io.inright image2.tif -epi.step 1 -io.outimage1 outimage1_grid.tif -io.outright outimage1_grid.tif But, the command hanged/stuck while writing outimage1_grid.tif. The command worked very slow and did not utilize all cores on my PC. I will be grateful if some let me know following: 1. How does the grid generator make the transformation grid (algorithm ?), why it is so computationally expensive? 2. Can I run the grid generator using mpirun -np 4 otbcli_StereoRectificationGridGenerator -io.inleft image1.tif -io.inright image2.tif -epi.step 1 -io.outimage1 outimage1_grid.tif -io.outright outimage1_grid.tif? I also noted that the grid generator worked nicely with -epi.step 5. But the issue is I want to process the data at the full resolution (i.e., all pixels in the raw image). How can I do that? -- Kind Regards M.
