Title: Reflectance calibration does not produce the results shown in the tutorial
Post by: t.h on November 13, 2020, 07:59:24 AM

Hello,

I am trying the tutorial for ALTUM spectral camera's reflectance calibration.
https://agisoft.freshdesk.com/support/solutions/articles/31000148780-micasense-rededge-mx-processing-workflow-including-reflectance-calibration-in-agisoft-metashape-pro

I got reflectance values CSV from micasense and loaded it into Metashape.

In the tutorial, generated dense point cloud and orthomosaic is RGB colored,
But when I tried same procedure in the tutorial, always I get "Black" orthomosaic and pointcloud.

Do you know to solve this phenomenon?

Best Regards,

I tried to divide each bands by 8192, it displayed like attached.

do you think this setting is right?

Hello t.h,

If you need to get the good-looking RGB output, then you can adjust the coefficient in the formulas and then use Index Color option in the Raster Transform section of the Export Orthomosaic dialog.
