Could not find ccd_width in file. Use --force-ccd or

ODM
#1

I have installed Docker for Mac v18.03.0.
Then in Terminal I typed :
git clone https://github.com/OpenDroneMap/OpenDroneMap.git
then cd OpenDroneMap
docker run -it --rm -v $(pwd)/images:/code/images -v $(pwd)/odm_orthophoto:/code/odm_orthophoto -v $(pwd)/odm_texturing:/code/odm_texturing opendronemap/opendronemap

Then I put 420 jpg files into the images folder and run the same code once more
docker run -it --rm -v $(pwd)/images:/code/images -v $(pwd)/odm_orthophoto:/code/odm_orthophoto -v $(pwd)/odm_texturing:/code/odm_texturing opendronemap/opendronemap

Then I added the flag force-ccd
docker run -it --rm --force_ccd -v $(pwd)/images:/code/images -v $(pwd)/odm_orthophoto:/code/odm_orthophoto -v $(pwd)/odm_texturing:/code/odm_texturing opendronemap/opendronemap
unknown flag: --force_ccd

Am I doing something wrong?
What is the size of the P4P sensor? Where do I put that value?

#2

It’s not really an error to not have ccd_width, just a warning. Did it finish running, or did you run into an error later?

#3

I have the same issue. I also have a P4P. Its sensor size is 13.2 by 8.8 mm. The P4P camera is not included in the OpenSfM sensor_data.json list. The sensor_data.json file doesn’t reside on my computer after I am done generating my Docker image. Is there any way to include the sensor size as a flag when I run ODM in Docker? I believe the sensor size enters into the calibration of my ortho_texture and ortho_photo. Currently all of my measurements are too short.

Thanks for help.

#4

I figured it out how to use the force-ccd flag. I added “–force-ccd 13.2” after my_odm_image and it ran without error.

However, it didn’t make a difference in the length calibration. I am getting the same measurements as I did without specifying the sensor size. I wonder what else could make all of my measurements about 6% shorter?
