For mapping agricultural surfaces we use a drone with several nadir-looking camera mounted on it. We’ve been planning the flights with Pix4D capture and trying to process them with Pix4D mapper.
Unluckily we are having a lot of trouble with the processing part, out of the many datasets we collected we could only stitch few of them, the majority of them don’t go through step 1 of the processing and we don’t understand why. The error message which is appearing all time is “no calibrated cameras”.
The dataset has good quality, the overlap is high and the surface is not too homogeneous (I also tried using Alternative calibration method). Images have been taken with a FLIR Blackfly-S 5MP.
What could the problem be, how can it be solved?
