Dear All,
I tried to do OpticalCalibration with TOC correction on two Pleiade datasets.
The first dataset (located in Canada) didn’t worked, the resulting images are black with red and yellow contour lines.
The second dataset (located in patagonia) worked (no more blue shadow), but when I am trying to orthorectify it using MicMac (the French IGN photogrammetry opensource software), I just have a black image.
Do you know those problems, especially concerning the first dataset ? Is there a way to solve it ?
Thanks for your help !
Thanks for your answer, I forgot a lot of parameters ^^’
I am operating under Ubuntu, and OTB version 7.1.0, and I guess I am using the binary files, because I am launching Monteverdi using mapla.sh…
I installed OTB using OTB-7.1.0-Linux64.run
Does it help you ?
Dear @AnaisE,
If I understand correctly, you are using Monteverdi to process your datasets? Could you share with us a screenshot of the parameters you set for the processing? And also the logs you obtain?
Sincerely.
Julien.
Hello !
I joined pictures of the parameter with the maritime aerosol model, and a picture of the result with no aerosol model choosed (which is the better choice for now). OTB_param.pdf (244.5 KB)
Here is the log :

Also, I noticed you set the parameter level to toa, but in your original question you were talking about TOC correction. (but I don’t think it is the source of your problem)
I personally don’t see the error, I suppose that the values of dates and angles calculated by OTB are not the good ones, but I don’t know how to check that.
Here is the log from the command line, the result is the same :
I don’t see why your processing results in a black image. Did you check the dynamic of the output image?
Just to be sure the parameters are correct, you can try to run the program with the command line and without the parameters, and see what the program finds : ./otbcli_OpticalCalibration -in /data/Labrador/Traitements/Dossiers_images/zip/2018-006-Sci-P004-Univ-Rouen-C.Colange_SO18010794-6-01_DS_PHR1A_201909131530380_FR1_PX_W062N56_0918_01258/TPP1601254289/IMG_PHR1A_MS_004 -out /data/Labrador/Traitements/Dossiers_images/OpticalCalibration_Marit.tif -level toa
