How to export variance of tie point?

Hello,

I would like to use the variance of the tie points to show the accuracy of DSM created by Meatashape.

How to export variance of tie point?

I hope to overlay the variance map of the tie points with exported DSM in the GIS program.

It is not easy to find the way of exporting it  in Metashape GUI. If you can give me any simple python program, I really appreciate it.

Furthermore, If the variance of the tie points is not the good idea in order to suggest the accuracy of the DSM, Which things are better?

Best,

Hey,

If it's only because of an accuracy matter, you can produce a dense cloud with the confidence index option enabled and then, export it as laz. The laz format will allow you to import it in Qgis to perform your accuracy presentation.

Many thanks to you.
