Title: Export xyz coordinates of Markers (version 1.1.6)
Post by: latexx on July 29, 2015, 01:30:19 PM

I was looking for how to get the xyz coordinates of markers. I guess there is only one way to get them, a script. So, I try to update this script to version 1.1.6 but I can't do it (I don't know a lot about phyton ...).

http://www.agisoft.com/forum/index.php?topic=1157.0

Code: [Select]

# exports all markers in activeChunk to csv.
# compatibility: Agisoft PhotoScan Professional 0.9.0
import PhotoScan
import math


FILEPATH = 'C:/marker_export.txt'

app = PhotoScan.app
doc = PhotoScan.app.document
chunk = doc.activeChunk
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 = PhotoScan.Matrix.diag( (1,1,1,1) )
T = chunk.transform
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()

So, can someone help me or give some orientations?

Thank you!!

Hello latexx,

doc.activeChunk -> doc.chunk
chunk.transform -> chunk.transform.matrix

Thanks a lot for your reply!!!  :D :D

I changed it and now I have other problem:

Traceback (most recent call last):
  File "C:/******/python.py", line 22, in <module>
    v_t = T * v
TypeError: unsupported types

Could you say me something about this??

Again, thanks!!

Sorry!! The problem is:

Traceback (most recent call last):
  File "C:/******/python.py", line 25, in <module>
    v_out = proj.project(v_t)
AttributeError: 'NoneType' object has no attribute 'project'

Hello latexx,

the error indicates that no geographic coordinate system is defined for the chunk.

You can try the following script where the additional check is implemented:

Code: [Select]

import PhotoScan


FILEPATH = 'C:/marker_export.txt'

app = PhotoScan.app
doc = PhotoScan.app.document
chunk = doc.chunk
f = open(FILEPATH, 'w')
for marker in chunk.markers:
if marker.position == None:
continue
T = chunk.transform.matrix
v_t = T.mulp(marker.position)
if chunk.crs:
v_out = chunk.crs.project(v_t)
else:
v_out = v_t
f.write(item.label + ',' + str(v_out[0]) + ',' + str(v_out[1]) + ',' + str(v_out[2]) + '\n')
f.close()
