Camera Calibration / Re: white image with reflectivity calibration

Hi again

I Was wondering if you seen the subset of images I send a few day ago, to reproduce the issue with whiteness after the reflectivity calibration

Kind regards
Sebastián

Hello Alexsey

Actually no, if I calculate the NDVI value, generally is almost zero. That makes me absolutely no sense, because the prairie was almost green in the center of the model, where the cows were eating

The mean pixel value for the RED band was 62168 and for NIR 62825, thats say to me that almost all energy was reflected (if I understand it correctly for 16 bits resolution)

King regards

Camera Calibration / white image with reflectivity calibration

« on: May 28, 2019, 03:46:15 PM »

Hello

I have been working with a Parrot Sequoia+ in a Inspire2. And Agisoft Photoscan Pro
Yesterday I make a small flight and process the data obtain, with the reflectivite calibration through the Sunshine Sensor.
But the image resulting is all most white, is this normal? Has anyone had this problem?
the flight was make at mid day in a clear sky day

Thanks!

Pd:I add an image as an example
