Hello,
I am using OTB with Qgis to make TOC calibration for Pleiade images.
I get a result of a white and black image (white = 10 000 and black = 0). I checked the parameters from the DIM file, it seems to be correct i also tried to correct gain and bias text file but i have the same problem every time.
Some one had the same problem?
Thank you
