"unkown location"

[jayrajkharvadi]

Hello Stuart,

many thanks for creating this addon. I used for a couple of projects. Now, suddenly it has stopped working.

I have tried using it with Colmap, PMVS, visualSFM . I also tried using it across different versions of blender (2.8, 2.81, 2.90.1, 2.91 beta, 2.92 )

Specs : OS : windows 10 Processor : intel i7 7700 Graphics card : 1070 mobile.

Can you help me please? Console output below. Thanks, Jayraj

This is what is output in the console window.

Was there any more console output? Usually <unknown location> is accompanied with a stack trace. e.g.

process photogrammetry
in_bundler
out_bundler
Traceback (most recent call last):

I've made some code changes in the master branch for better feedback from known issues (e.g. properties with missing or incorrect values), and changes to get rid of the type annotation warnings on startup.

It may not relate directly to your issue, but is easier to identify unhandled exceptions.

Thanks for the response Stuart and apology for the late reply. I removed the previous installed version of the addon and I installed the latest version from master (1.2.0) on blender 2.90.1.

Hope this helps.

Here is the output from the window console.

Hi jayrajkharvadi - I've just had another look at your output. It looks like there wasn't a successful reconstruction from blender, so it eventually gets to a point in COLMAP that fails because it's working with 0 images: Fusing image [1/0] - i.e. no images.

Reading back through the log you'll see this output: {'cameras': {}, 'resolution': (4096, 2304), 'trackers': {}} meaning the data extracted from blender had no cameras or trackers. I should probably put a test case in for that scenario to inform the user that the input needs investigating. In this case, that you need to check that the motion tracker successfully solved the motion first.

I also found this error in a project where COLMAP crashes mid-process. I need to investigate further as to why it's occurring.
