Hi Julian, Working on similar task and flowing this discussion - hence starting with stereo model of 2 Pleiades images I would like to refine the sensor model before extracting DSM as discussed in the cookbook -- e.g. I all-ready extracted DSM usefully and now I want to refine the solution.
I extracted homologous points with 2wgs84 option set to 0 (both h' points are in image C' system). I got text file with about 3000 points in image coord' system. To verify if the points are good one need to overlay them on the image ... *-- is Monteverdi support such task or other known tool ?* Then I continue with RefineSensorModel otbcli_RefineSensorModel -ingeom c:\data\PMS_002.geom -outgeom c:\data\PMS2refinedGeom.geom -inpoints c:\data\homologous_points.txt -elev.dem c:\data\dem -elev.geoid c:\data\dem\egm96.grd -outstat c:\data\stats.txt and I got this info for each H' point 2014 Feb 21 12:44:06 : Application.logger (INFO) Adding tie point x=2435.83, y=7708.88, *z=-1.#QNAN*, lon=2379.94, lat=7468.34 it looks that I have a problem with the z value ??? I supply DEM dir which include DEM files & geoid file and then the prog' crashed after displaying this 2014 Feb 21 12:44:06 : Application.logger (INFO) Optimization in progress ... -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNA N -1.#QNAN -1.#QNAN -1.#QNAN -1.#QNAN 2014 Feb 21 12:44:12 : Application.logger (FATAL) An unknown exception has been rais ed during application execution It sounds like a problem the z ? *Do have any idea regard this error ?* thanks Ofer On Monday, April 22, 2013 4:15:49 PM UTC+3, Julien Michel wrote: > > Dear Myriam, > > Thank you for your answers.
