Hi, It is rather difficult to answer this question, it depends on the landscape, acquisition date, angles … If the two images are acquired on the same date, there should be more point … Did you try to play with parameters a bit ?
Also I see that you are using pansharpened (PMS) data, they are not the best for stereo-reconstruction … Regards, Julien De : otb-users@googlegroups.com [mailto:otb-users@googlegroups.com] De la part de anamaria.loghi...@gmail.com Envoyé : vendredi 2 mars 2018 19:40 À : otb-users <otb-users@googlegroups.com> Objet : [otb-users] HomologousPointsExtraction Dear otb-users, I'm also trying to apply the otb toolbox for a stereoscopic reconstruction, based on Pleiades images. I have applied the HomologousPointsExtraction using the calibrated satellite images (calibrated with otbcli_OpticalCalibration, te top of canopy level). This is my line command: otbcli_HomologousPointsExtraction -in1 "P:\Projects\Bild_001\DIM_PHR1B_PMS_201706131009515_SEN_2360439101-001_1.tif?&skipcarto=true" -in2 "P:\Bild_002\DIM_PHR1B_PMS_201706131010111_SEN_2360439101-002_1.tif?&skipcarto=true" -algorithm surf -mode geobins -mode.geobins.binstep 512 -mode.geobins.binsize 512 -mfilter 1 -precision 20 -2wgs84 1 -out P:\Projects\IMAGE_MATCHING\homologous_points.txt -outvector P\IMAGE_MATCHING\points.shp -elev.dem "P:\Projects\IMAGE_MATCHING\DEM\DEM10m\DTM.tif" -elev.geoid "P:\Projects\EGM96\egm96.grd" I have as result the 'homologous_points.txt' file containing only 7 points.....is that fine? shouldn't be many more points? The result file is in the attachment. Please, if anyone knows this and can answer me I would be grateful.
