Description
Hello,
We have a ploblem in new version v0.3.0.
[Problem]
We try to generate 3D point cloud of highway.
Only a start point of the generated point cloud data is increased in size.
OpenSfM v0.2.0 does not have this problem.
This problem only occurs when point cloud data is generated with GCP / without GPS.
Does anyone know anything about this problem?
According to the release notes of v0.3.0, following two settings were changed in new version.
Dose following two settings affect this problem?
[Changes due to version up].
1, Local bundle adjustment is used by default
2, Changed default FLANN parameters for faster, less precise matching
Thank you for your help.
