We are getting a DJI P4 Multispectral drone and Pix4Dmapper for image analysis. Still, we have to decide which calibration panel is the most convenient to use with Pix4Dmapper + DJI P4M.
As I noticed in the Pix4D description, the calibration is very easy using a MycaSense reflectance calibration panel. But here’s the problem - you cannot get it if you don’t own a MycaSense camera.
I came across MAPIR Camera Reflectance Calibration Ground Target Package (V2) - MAPIR CAMERA panel. They also provide reflectance data for 350-1100 nm wavelength in 1 nm increments with that product. Would it be easy to calibrate the images taken by DJI P4 Multispectral by using Pix4Dmapper and Mapir calibration panel?
Or should I buy a plain 18% gray white balance card and be happy about it?If you have any suggestions or experience on this, please share with us.
