Auto exporting of multiple single photos to ortho

[Alexey Pasumansky]

Hello bisenberger,

By default the orthophotos are saved to the folder with the project file.

But you can change the assignment of the path variable in  def exp_ortho(self) function to:

Code: [Select]

path = PhotoScan.app.getExistingDirectory("Browse for the export folder:")

Hi Alexey,
I went ahead and downloaded the rest of the scripts posted on the wiki.

All are very useful.
Thanks,

Works nicely. I can export large areas with low RAM (8Gb) and then recombine in GlobalMapper

Dear Alexey,

I have an problem while running your script.

My Dataset aint got no camera position files, but an generic alignment and just markers for generating orthophotos.

If i run the script after proceeding every single step i`ve got the following error:

Traceback (most recent call last):
  File "G:/2012-01_STC_Venezuela_Lake-Valencia/Thomas/prio5/ost/prj/try.py", line 83, in <lambda>
    proc_exp = lambda : self.exp_ortho()
  File "G:/2012-01_STC_Venezuela_Lake-Valencia/Thomas/prio5/ost/prj/try.py", line 272, in exp_ortho
    v1 = PhotoScan.Vector((crd[0], crd[1], 0) )
TypeError: 'NoneType' object is not subscriptable

I would be delighted to read from you.

Best regards Tommek

Hello Tommek,

Could you please specify, what coordinate system is defined in the Reference pane settings dialog?

[tommek01]

Hey Akexey,

thanks for the reply. It's WGS84/UTM zone 19N.

Regards

[Alexey Pasumansky]

Hello Tommek,

Thanks, it seems that wrong criterion has been used when checking if the coordinate system is projected or geographic. I've modified the script (changed only one line):

Code: [Select]

...
#recalculating WGS84 resolution from degrees into meters if required
if chunk.crs:
if not ('PROJCS' in proj.wkt):
...

So please check if it works fine now.

[tommek01]

It works. That ist amazing.

thanks a bunch!!!!!

[Alexey Pasumansky]

OK, nice to hear that.

Note that in the next version (that is currently available as pre-release), we've implemented similar feature to GUI interface for user convenience.

Hey Alexey,
I have one question in addition. Is it possible to include an all over color correction befor exporting the single orthos?

Blessings Tommek

[Alexey Pasumansky]

Hello Tommek,

At the moment it is not possible, since color correction is only applicable to the images used for the orthophoto export, and if there's only one image per individual orthophoto, color correction couldn't be applied.

Hi Alexey,

In running Export Individual Orthophotos.py I am not getting a result from the script when I run with the option for a single selected image.  In the console, although the process appears to be working it exits with code 0 and fails to produce an ortho.  Just wondering if I might be executing something improperly.   Thanks for any advice you might be able to offer.

Hello Rob,

Maybe you can send the screenshot of the script dialog and the full Console pane ouput related to the export operation?

But probably, you can update to the version 1.2 and use built-in functionality in Tools Menu -> Export -> Export Orthophotos to save individual images. This functionality can be used after the orthomosaic is built using the corresponding option in Workflow menu.

Thanks for the reply Alexey,

I'm attaching a screen shot of the console in addition to the startup and finish dialog from running the script.  I'll update this evening and give it a shot.

Hello Rob,

I have two ideas of possible reasons causing failed export:
1) Export resolution is two high so the size of individual orthophotos is higher than 4 GB for GeoTIFFs.
2) The document has not been saved prior to the script start. Script exports the orthophotos to the folder containing the project file.
