I did some processing test with pix4d a while ago and I was studying again all the data and outputs from it. The data was from a corridor map data from sensefly. I noticed that the quality report from both proccess are different (sensefly RMS error is just mm and I got cm). What could be the reason for this different accuracy in absolute geolocation data in both projects? Could it be the set of parameters, or maybe is according the capability of process of the computers?
Here are both quality reports, from sensefly and from my processing.
