DJI P4 Multispectral + Pix4Dmapper + ??Which Reflectance Calibration panel??

Pix4Dmapper
#1

Hi all,

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.

Many thanks,

Good Day

Trust you are well,

Could you please assist, we need assistance with Pix4D Mapper.

  1. We recently purchased a DJI P4 Multispectral drone for agricultural purposes. We have since not been able to successfully process any of our projects. We continuously receive errors stating “Camera Calibration”, Could you please assist us in rectifying the error?

  2. Do you perhaps have a reflectance image for us or where would we be able to get it?

Your quick response will be highly appreciated.

Thanking you in advance.

Kindest Regards,

Can you provide the quality report and the log file of the project?
