Help for Fresh Noob_OrthoPhoto:"Process exited with code 1"

sunhoro · 13 November 2019 02:58

Hello all, I just started to use WebODM and pretty excited.

I am running this on Windows PC with 3.5 ghz CPU and 16GB RAM
I installed WebODM with Docker Toolbox: tested with other shared images and worked fine
I am using DJI Mavic 2 pro

My goal is to make an orthophoto for google earth change detection and possibly a nice 3D model.
I have no clue on what and how to edit among the options so I have been using either “Default” or “Fast Orthophoto.” It will be great if there is any link to study how to play around with the options.
Please see link for images that I am using (26 drone images) and MS Word file for error task output: https://drive.google.com/drive/folders/1LoN6OeoG1pIxa1PMhq2Jz0n5WTeTnqS7?usp=sharing
These images are taken from drone video so I had to manually input the relative GPS coordinates.
When I run these images on WebODM I always get an error: “Process exited with code 1”
The entire process took 3min and 47 sec on my computer (probably it stop midway cuz of error)
Can anyone help me out with what the issue is and how to solve it?

Thank you so much for the help!!!

Hello Sunhoro,

It would be helpful if you provided at least the ending portion of your error trace. I’m certainly not an ODM expert, but any issue is hard to diagnose without error information.

Second, why are you using video and estimated positions? Your Mavic is fully capable of collecting high-resolution images with embedded GPS. I do it all the time with mine. This will help alleviate issues you may be having if your positions are not accurate enough. Also, they will be significantly higher quality than you could ever get from a video extraction. If you are new to this type of data collection and processing, I recommend using a flight planning app like Pix4D Capture, MapsMadeEasy, or DroneDeploy to help you collect the imagery and make sure you are getting the proper overlap and sidelap. You can still process the files in ODM. I’m partial to Pix4D capture. It has always worked well for me.

Hello Sarko,

Please see last part of the error trace below
Yes Mavic is pretty awesome to use. But the video that I want to use is the one that took with out knowing all the knowledge when I was a fresh to drone. I did did not turned the caps on and did not realized image was way better than video. I am just trying to do as best as I can to use the images for mapping (estimated GPS is still from the flight log so it should be close enough).
Mine issue could be from inaccurate GPS.

Hello,

So, from the beginning of the error trace it is clear that ODM is not properly reading the GPS data from the images. You said you imported the GPS information yourself. How did you do that? Did you use a standard library like pyexif or something along those lines? The GPS Exif data must be inserted as a Rational in a very particular way, so it isn’t necessarily straight forward. That is definitely something to fix.

After that it looks like ODM is able to match some images and tried to generate two partial reconstructions. These fail to generate properly. I know you said you extracted video frames. How much overlap do you have between frames. You need at least 70% or so from frame to frame to get a good reconstruction. Do you have that?

Those are the first things I would check.

I used a free software called “EXIF Pilot” to manually add longitude and altitude.
Yes, all the images should have about 50%~70% overlap.

I guess I will try to use another method to add GPS to the images.

What do you see if you run gdalinfo on one of the files? Do you see the correct values for the position and altitude? Also, if you think some of your images are in the 50% overlap range, this may explain why your project split into two partial reconstructions. 50% is not enough and I know many on this forum say you should be near 70% all the time. I’ve used images that were between 60 and 70% overlap with pretty good success, but I think being >70 is a good goal if you can do it.
