Exif: Incorrect radiometric sensitivity

PIX4Dmapper

Hi,

When I load a project, I always got the following warning for every image:
[Warning]: Exif: Incorrect radiometric sensitivity

I’m using Micasense Altum cemera and I’m sure that there is light sensor on the top of drone. So I’m confused about this warning. Can anyone help with this…

Thanks in advance!

Hi, The reason for this is that the thermal image contains Xmp.MicaSense.RadiometricCalibration XmpSeq 3 0, 0, 0 which is incorrect. However, there is no radiometric correction done for the thermal band, therefore the incorrect tag doesn’t have any effect. Newer firmware versions don’t tag any Xmp.MicaSense.RadiometricCalibration for the thermal band anymore and the error disappears. You will need to update your firmware.

Thank you! I’m clear now!

Hi Momtanu, can I ask what firmware needs to be updated? MicaSense Camera or laptop for processing images? Thank you very much.

Hello,
You will need to update the MicaSense Camera firmware to the latest version. However, I recommend also using the latest version of PIX4Dmapper as this version fixed the orthomosaic creation for 12bit images. This fix impacts the MicaSense Altum.

Thank you Mike. Updated version does work for orthomosaic. Cheers.
