Height error with GCPs
« on: March 09, 2018, 02:47:00 PM »
Hello,

maybe someone has an idea on the solution.

I used GCPs for georeferencing my project.
The coordinates are imported correctly as i can see in the reference pane.

But then i go to "show computed coordinates" the coordinates for the reference points are different.

When i now create new points they seem to have the height from the computed points, which is wrong.

For example:
Import 4 reference points with a height of 100m. Agisoft Photoscan pro is computing a height about 2m deeper, 98m.
When i then create points and export them they also are at 98m height.

Hello Sascha,

Can you provide the report file from the project?

Also do you optimize the camera alignment after placing markers and loading their coordinates?
