Hi all,

I am trying the same export with you code but I get the same error "TypeError: unsupported types" at line "v_t = T * v".

But my project is referenced as there is a [R] beside the chunk name, and "str(type(T))" gives "<class 'PhotoScan.ChunkTransform'>".

I am using APS 1.3.4

By the way, it seems that on this version of APS, the PhotoScan.Matrix.diag( (1,1,1,1) ) is wrong and "diag" takes a capital :
PhotoScan.Matrix.Diag( (1,1,1,1) )

But not a problem in my case as my chunk.transform exists.

Thanks for your precious help !

Hello Guilhem,

Please try the following code in 1.3.4:

Code: [Select]

# exports all markers in activeChunk to csv.
# compatibility: Agisoft PhotoScan Professional 1.3.4
import PhotoScan, math
FILEPATH = 'E:/marker_export.txt'

doc = PhotoScan.app.document
chunk = doc.chunk
T = chunk.transform.matrix
f = open(FILEPATH, 'wt')
for marker in chunk.markers:
   if not marker.position:
      continue
   v_t = T.mulp(marker.position)
   v_out = chunk.crs.project(v_t)
   f.write(marker.label + ',' + str(v_out[0]) + ',' + str(v_out[1]) + ',' + str(v_out[2]) + '\n')
f.close()

Ok I got it work with APS 1.3.4 (I guess the problem was due to changes in calls with last version of APS)

We have to specify "chunk.transform.matrix" and not "chunk.transform" before doing "v_t = T * v" otherwise APS does not understand ad chunk.transform contains several things beside the ".matrix".

Beware also with the "PhotoScan.Matrix.Diag" with captial for "Diag", in case needed... (old version did not take a capital)

FILEPATH = 'G:/marker_export.txt'

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 = PhotoScan.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()

Cheers
