I am using OTB to make TOC calibration from WV3 images.
I get a result of a white image (values = 1). i tried to correct gain and bias text file but i have the same problem every time.
Some one had the same problem?
It is the first time I see this error. Sorry you encountered it.
Could you tell us what version of OTB you are using, how do you run the application (command line, QGIS, other), the parameters you set, and the logs you obtain? With this information, we will try to find out what’s going on.
For gain and bias, i use this structure for .txt format as described in documentation :
Here is an XML file showing parameters used :
OTBparamameters.xml (8.7 KB)
Here is the file containing log information :
log_OTB_calibration.txt (5.5 KB)
I use both monteverdi and Qgis3.14 and OTB version is 7.2.0
I am surprised to read in the log file that all your bands have the same wavelength (0.65µm). Maybe a problem with the metadata. Could you try to run a gdalinfo on one of the images?
Your gainbias.txt file seems well formatted.
I have the same problem but with images gaofen-1 WFV4 and running directly in monteverdi.
