Architecture reconstruction scale

Development Asset Creation Photogrammetry

Im using reality capture since 2018 for architecture reconstruction and photogrammetry. Main tools used where dji mavic 2 and reality software present at the time, everything went smoothly, never got any glitches.

Since the upgrade on reality capture 1.4 and dji mavic 3 i am constantly getting models out of scale. Texturing, reconstruction, model everything is done perfectly expect for scale, it usually is of by some percentage ( typically 30 to 50% off scale - usually model is bigger).

Im unable to find the reason for this miss alignment and it bothers a lot because im unable to trust my workflow since.

Any advice would be very appreciated

Hello @Skekur
How are you scaling your models? Are you using only georeferenced data from the drone’s images? If so, these can be quite unprecise.
To scale your models more properly try to use GCPs or at least scales during your capturing.
