Ground control points & coordinates

Dear Jane,
the component 1 is the correct one. The thing is that the application automatically center the object so that it can be visible in the 3D view. However it is not a mistake it is intended to be so. Next you can compute model and then an ortho projection. Then you will see the correct coordinates for the mouse possition in the left down corner of the ortho projection 2D view. Furthermore if you set “Preserve Coordinates” to true during export of the model then the exported model will contain correct coordinates of the model vertices as well.

Yes it works! Thanks!

Does anyone know what is the best method to get the best location accuracy? Is it better to set ground control points in every photos where the black&white targets are visible? Or is it better to set ground control points only some photos and let the software do the calculations. By decreasing the number of manually tagged GCPs the human error is smaller and it also saves time.

I’m used to make coordinate based registration on AutoDesk ReCap. In Recap 4 manually tagged photos for one GCP is enough to make a good result
