I thank you very much for your guidance…
but I need to know if I can use the values provided by the MAPIR radiometric target (87% R, 51% R and 23% R) by entering these albedo values (0.87, 0.51 and 0.23) in the Index tab Calculator to calibrate the bands.
I sent an e-mail to MAPIR and received this information: “We do not recommend using Pix4D for calibration since they only support a single target for calibration. We recommend running the orthomosaics through our MCC calibration process. If you still want to try using the albedo values you can look at the peak value in the target datasheet. The albedo values should be the peak reflectance at the peak of the transmission transmission wavelengths. The% R means that is the average reflectance value for that target material. We don’t offer support outside of our MCC application, sorry”
I’m new to PIX4D and I’m asking for your help to solve this problem… Forgive me.
