RealityScan 2.1 — How to restore “Shifted project output” back to EPSG:4326 / WGS84 coordinates?

General Tutorial & Course Discussions

Hello everyone,

I am using RealityScan v2.1 and have a question regarding coordinate systems when exporting camera parameters and models after reconstruction.

Background

  • My Project output coordinate system is EPSG:4326 / WGS84 (longitude, latitude, altitude).

  • When exporting camera parameters (and/or other data), I selected “Shifted project output”.

  • As a result, the exported files contain coordinates relative to the reconstruction center, rather than absolute WGS84 coordinates.

My question
How can I correctly restore the exported “Shifted project output” coordinates back to the original Project output coordinates, i.e. absolute EPSG:4326 / WGS84 longitude/latitude/altitude?

Hi,
with the model there is also an option to export the transformation file. The used transformation is written there. Also, when you are importing the model back to RealityScan, this transformation is applied.

For the camera parameters I suppose you also need to apply that transformation to get the proper coordinates. But there the easiest way will be export camera parameters in the output CS.
