Title: Loading gcp coordinates from .txt or .csv in 1.3
Post by: ArchaeoloGIS on March 24, 2017, 07:58:59 PM

Is it possible in the current v.1.3 to load marker coordinates from a file using script and if yes how.
Sorry if the question is stupid but i am a newbie in programming and can't find out how to do it or if it's even possible with current version.

Hello ArchaeolgoGIS,

You can do it using the same function that loads the coordinates for the cameras:

Code: [Select]

chunk = PhotoScan.app.document.chunk
path = "D:/markers.txt"
chunk.loadReference(path, format = PhotoScan.ReferenceFormatCSV, delimiter=",", columns="nxyz")
the same of the file for such function is the following:

Code: [Select]

point 1,123.321,124.432,543.1

That is a fast reply. Thank you for the help.
So when i run the script i get some error -
2017-03-25 11:05:20 Traceback (most recent call last):
2017-03-25 11:05:20   File "H:/DAMJANICA_ALL/Damqnica_obekt_16_AM_STRUMA_LOT_33/PHOTOGRAMMETRY/script_for_loading_GCP.py", line 3, in <module>
2017-03-25 11:05:20     chunk.loadReference(path, format = PhotoScan.ReferenceFormatCSV, delimiter=";", columns="nxyz")
2017-03-25 11:05:20 OSError: Can't load reference: H:\DAMJANICA_ALL\Damqnica_obekt_16_AM_STRUMA_LOT_33\PHOTOGRAMMETRY\TERESTRIAL_CLOSE_RANGE_08_2016\SONDAJ_31_08_sondaj_31_GCP.csv
I have noticed that for some reason the path is changed and instead of 23 i have !!
The file path must be H:\DAMJANICA_ALL\Damqnica_obekt_16_AM_STRUMA_LOT_33\PHOTOGRAMMETRY\TERESTRIAL_CLOSE_RANGE\23_08_2016\SONDAJ_31\23_08_sondaj_31_GCP.csv
Tried to change the file name and dir and when i load the script and click ok nothing happens, if i load the file manually from import markers icon it works. We use coded target if it maters.

Hello ArchaeoloGIS,

Can you change the "back slash" symbols in the path to the regular "slash"?
