I marked 7 GCP’s and 3 checkpoints. I noticed that the error for some reason was much more for the checkpoints as opposed to the GCP’s I created. The GCP’s seemed to be spot on. I know that checkpoints don’t go into the computations, but I’m just trying to understand my absolute accuracy here.
Is it possible that I just didn’t match images good enough for the checkpoints as opposed to the GCP’s? I don’t understand the purpose of checkpoints if each GCP can give you their own margin of error from their original spot before you correct with image matching.
Please explain this to me, as maybe I’m not really understanding checkpoints. I’ve attached my QR. I’m going to need some detail, so please don’t just send me a link to an article as I’ve read all of them that Pix4d has to offer on this subject.
Thanks ahead of time!
