Hi Dukytony,

here is our script for 1.4.1.

Best regards,
Marcel



Code: [Select]
"""
/********************************************************************************************************************
                                    OPEX - Orthophotoexport (V. 1.10)

                                                    Content:
  Processing code to exports orthophoto in planar projection defined by vektor (from three markers) and Z axes.
  This code is mainly for exporting archaeological profiles; ready for importing in GIS.
  Before using the script you need:
  - A georeferenzed Model
  - An "A" and "B" Profile Nail (Named "A" and "B" in Photoscan)
  - A "Y" Point in Photoscan with the coordinates (X-coord from "A",Y-coord from "A", Z-coord from "A"+ a high number)

  Compatibility - PhotoScan Professional 1.4.1
  Version - 1.10

Can anyone confirm if this works in 1.5? I've tried running it and it just freezes upon trying to build the orthomosaic.

Hi matt07lx,

we are currently using Metashape 1.5.2 and it works just fine. I suppose you would like to have the current code from us? I ask my colleague if I may insert it.  ;)

Best regards,
Marcel

Hi matt07lx,

as Marcel mentioned before we use the following script for Metashape 1.5.3. and it works fine.
We hope that it´s usefull for you.

Florian,

Thanks so much for sharing the latest version of the script. When I run it now I get the following error: "UnboundLocalError: local variable 'a' referenced before assignment". Do you have any thoughts as to why I am getting this error?

Hey matt07lx,

in my opinion this error occurs because you don´t have a nail with the name "A" which is needed as the starting point for the profile.
Please ceck the requirements of the script which are written on top of it.

Let me know if it helps.

Best regards,

Florian

Hi all,

we found your script by chance and tried to use it with Metashape 1.6.2 but failed. Is it possible that something changed between Metashape 1.5 and 1.6 that prevents a proper usage?
If so, would it be possible to post an updated version or give us a hint, what we have to change within the script to use it?

Many thanks
Jan
