It has been quite sometime since using WebODM. The UI is quite user-friendly. I can upload the photos and get the results on time. All are downloadable. Big kudos to the team .
Recenlty, I have been trying to automate the things and got to know about the PyODM.
Being familiar with Python, I felt it is the right path for the automation. I have achieved the automation part as well.
But there is huge time difference between the processing time and I feel that I might be doing something wrong.
Using WebODM is quite startforward.
I have followed the instructions from Welcome to PyODM’s documentation! — PyODM documentation
Both of them uses NodeODM container, so according to my understanding both should have the same processing time.
I used 1k images and I was monitoring the logs of NodeODM.
info: About to run: /code/run.sh --min-num-features 24000 --mesh-size 250000 --crop 0.01 --auto-boundary --pc-filter 0 --pc-geometric --dtm --dsm --dem-resolution 1 --orthophoto-resolution 1 --rolling-shutter --pc-ept --cog --project-path /var/www/data 06e05a1c-9014-4be9-a0f0-d0b7223162aa
First of all, I did not use
--cog parameter here, but I guess it was set by default.
info: About to run: /code/run.sh --min-num-features 24000 --max-concurrency 36 --mesh-size 250000 --crop 0.01 --auto-boundary --pc-las --pc-filter 0 --pc-geometric --dtm --dsm --dem-resolution 1 --orthophoto-resolution 1 --rolling-shutter --rolling-shutter-readout 0 --project-path /var/www/data 8716522a-d656-4045-852c-dcea50fa107b
Here extra parameter which I have used is
--max-concurrency because I thought, the default value would be 4 only as indicated in the official documentation. But both the VMs had same configuration and total it has 36 vCPUs only. Also, I used
--pc-las as an extra parameter.
PyODM process is still running and it has been more than 17 hours. I feel there is something fundamentally wrong with my approach. I tested with few other smaller datasets as well and found the same observation only.
- Has someone experienced the same?
- What could be the next course of action to debug further?
Edit: Processing through PyODM took 22 hours 36 minutes (Almost 4 times).
