Sequoia multispectral bands not matching

[marike]

Hallo all,

I am experiencing the following error…

Exception: Cannot write /var/www/data/7ae16602-2779-450a-adcb-66c0e81a5c14/opensfm/undistorted/reconstruction_green.nvm, not all band images have been matched

A similar error was discussed in this previous topic except that I am analyzing Sequoia multispectral data using WebODM 1.9.2 on a Windows10 system.

Test data and complete console output can be accessed at:
test_data

Settings:
build-overviews:true, ignore-gsd:true, min-num-features:12000, optimize-disk-space:true, radiometric-calibration:camera, texturing-data-term:area, texturing-skip-global-seam-leveling:true, verbose:true
(I also tried with radiometric-calibration:camera+sun, but get “No sun sensor values” warnings)

Here is the last part of the console output for a test data-set:

Any suggestions?
Thanks in advanced

Are you on R23 with ODM 2.5.6?

Another user just surfaced a bug that might be affecting processing multispectral data.

Bug Report of ODM2.5.6 (ODM2.5.5 has no problem)

ODM 2.5.6 fails to process. This bug looks come from the modifications at Line 215-224 of “run_opensfm.py”. Editing 2 lines, remove " + ‘tif’ ", then ODM 2.5.6 run successfully. Dr. Chihiro KATO == ODM 2.5.5, run successfully ====== Primary band maps to itself if band[‘name’] == primary_band_name: img_map[fname + ‘.tif’] = fname + ‘.tif’ else: band_filename = next((p.filename for p in p2s[fname] if p.band_name == band[‘name’]), None) if band_filename is not None: img_map[fname + '.…

Thanks for the report! OpenSfM changed some filename handling and I thought we covered all cases, but apparently not.

Should be fixed with Fix Sequoia filename regression · OpenDroneMap/[email protected] · GitHub

Thanks for the fix, I have my first test ortho now!

Just to come back to the question:

Are you on R23 with ODM 2.5.6?

I did have a look and I had ODM 2.5.6, but what was meant by R23?

The release number for WebODM. You’ll see it on the blue splash screen when it is loading (next to build):

Ah thanks
