« on: July 18, 2019, 12:47:43 PM »

Hello !
I would like add the date and the time to my txt export file.
Below, the script, that i use to export my markers.
I want add Date&time after the Name of markers. Some help please for the script  ?

Code: [Select]


import Metashape, math
FILEPATH1 = 'C:/Alexandre/PFE/7.Couloir/Les_scène_refait/PYTHON/Export_donnée/Coordo_marker.txt'#lien fichier export

#Export des Markers


doc = Metashape.app.document
chunk = doc.chunk
T = chunk.transform.matrix
f = open(FILEPATH1, 'w')


for item in chunk.markers:
   if item.position == None:
      continue
   v = item.position
   v.size = 4
   v.w = 1
   if not chunk.transform:
      chunk.transform.matrix = Metashape.Matrix.Diag( (1,1,1,1) )
   T = chunk.transform.matrix
   v_t = T * v
   v_t.size = 3
   proj = chunk.crs
   v_out = proj.project(v_t)
   f.write(item.label + ',' + str(v_out[0]) + ',' + str(v_out[1]) + ',' + str(v_out[2]) +  '\n')

Python and Java API / How to export Markers location and errors pix in a txt file

« on: July 03, 2019, 03:21:57 PM »

Hello,
I would like export just some markers and the errors pix of them in a txt file.
I've found this code to export all markers location.

Code: [Select]

# exports all markers in activeChunk to csv.

import Metashape, math
FILEPATH = 'C:/Alexandre/PFE/Python/Resultat_export/marker_export.txt'



doc = Metashape.app.document
chunk = doc.chunk
T = chunk.transform.matrix
f = open(FILEPATH, 'w')
for item in chunk.markers:
   if item.position == None:
      continue
   v = item.position
   v.size = 4
   v.w = 1
   if not chunk.transform:
      chunk.transform.matrix = Metashape.Matrix.Diag( (1,1,1,1) )
   T = chunk.transform.matrix
   v_t = T * v
   v_t.size = 3
   proj = chunk.crs
   v_out = proj.project(v_t)
   f.write(item.label + ',' + str(v_out[0]) + ',' + str(v_out[1]) + ',' + str(v_out[2]) +  '\n')
f.close()

But how to make if I just want the markers

• ,[1],[2], [3], [4],[5]

In addition, I would like export the error pix of each marker. Is it possible ?

Regards,
Alex
