Micasense panel QR code not visible: how to manually locate
« on: September 21, 2020, 04:36:45 PM »
The QR code of the Micasense reference panel is slightly cut off the image and thus is not automatically recognized by the Tool  > Calibrate Reflectance > Locate Panels
Is there a way to manually select the panel image to be use for Reflectance calibration?
Thank you for the support!

Hi,

You can manually add your reflectance values in the same window, on the right side.

Follow the section Apendix A from this PDF and you should be fine:

Cheers!

Hello pdodo,

Please check the Appendix A of the related tutorial:
https://agisoft.freshdesk.com/support/solutions/articles/31000148780-micasense-rededge-mx-processing-workflow-including-reflectance-calibration-in-agisoft-metashape-pro

You need to put the cameras related to the radiometric panel to the camera folder in the chunk's contents and name it Calibration Images (unless it is automatically created), then review all bands (to switch use Set Primary Channel option for the chunk) and mask everything except the part related of the panel.
Best regards,

Thanks Alexey.
Following Appendix A and the workflow suggest by a previous user I:

1. Generate the mask for one single picture using the SELECTION TOOLS
2.  TOOLS > EXPORT > EXPORT MASKS. Save as a single channel mask image.
3. TOOLS > IMPORT > IMPORT MASK and select OK.

I do not see a cropped image, I assume that the algorithm just uses it to compute an average value over this area and then uses the value for the reflectance calibration, correct? So no cropped image is physically stored anywhere.
