Reference for the NVM format

[Mostafa]

Hello,

When I export cameras to NVM format, the parameters are defined in a local coordinate system, and I notice it is different from the one in the XML format.

How to transform the cameras and points at NVM format from the local to the global coordinate system?

Hello Mostafa,

You can try to export the cameras in geocentric coordinate system using the following Python code line:

Code: [Select]

Metashape.app.document.chunk.exportCameras(path = 'cameras.nvm', format = Metashape.CamerasFormatNVM, crs = Metashape.CoordinateSystem('EPSG::4978'))

Thanks Alexey,

I noticed when I save to NVM, it includes the failed/un-aligned cameras. Is it a bug? and is it also the case with other formats?
