calibration reflectance for camera MultiSPEC-4C
« on: February 23, 2021, 01:01:43 PM »
Hi everyone,

We try to align some photos taken by camera MultiSPEC-4C with Agisoft Metashape Pro 1.7.1.

But we met some problems when we want to calibrate reflectance, actually, we don't have a CSV file with calibration information.

Does anyone know where can I find these factors reflectance for this camera? We have only a calibration target in the box of the camera.

Thanks a lot.

Jeany

Hello Jeany,

It seems that the panel has been recognized on the single band only. For other three bands you should apply the masks manually.

The reflectance values for the panel should be provided along with the panel by the manufacturer. It is sufficient to input only four values, corresponding to each band.
