i would like to know if someone already has encountered this problem or situation regarding checkpoints and densified points on the densified point cloud.
My block is already adjusted to my 3D GCPs, the QR says it has a RMS error of 0.003 m which is pretty good.
Now here’s the problem.
i have already added several checkpoints in the project. i Reoptemized the project in order to check the consistency of the added checkpoints. the QR tells me that i have a 0.001- 0.006 error on the different checkpoints around the project which is actually pretty good, but here’s the strange part, when i zoom in to checkpoints, they seem rather far from the densified points on the point cloud, for example, one of the checkpoints is almost 25 centimiters long from the closest Densified point meanwhile the QR says that is has a 0.006 m error from the computed coordinated.
from what i’ve read and seen, we need to trust the statistics that the QR shows regarding the accuracy of the checkpoints added, but does someone know what does the actual distance between the computed and the densified point mean?
