I’m at the time lerning to make agricultural multispectral image analyzis using Pix4D. But I have a problem calibrating the multispectral images.
When loading the images into the softwere for Processing I am including the radiometrical calibration images taken before flight. I was hoping pix4d could recognize the calibration plate and do an automatical calibration. But it does not. In my folder containing the calibration images, I have three of each spectral band. One darker than the other. The brightest is overexposed. When going throu the process of calibrating the images manualy: which of the three images should I use? And why is the images not automaticaly calibratet in the first place?
I’m currently working in version 4.1.19 of the software.
Attached is a snippet of my screen showing the three different images in each spectral band.
