Comments on: Creating aerial imagery with a bike helmet camera (GoPro) and OpenDroneMap

I was really struggling with stitching spherical images from my GoPro Fusion and dealing with all the quirks of proprietary software. Just when I thought I’d hit a dead end, I came across this guide and finally managed to sort out most of my issues. Also, while looking for deployment solutions, I found this great resource on how to install Apache Airflow on Ubuntu, which was incredibly helpful for my project setup. It's amazing how the right tips and open-source tools can make seemingly impossible tasks manageable!

I’ve used a process documented at https://github.com/andrewharvey/lg360-mapillary-helpers to inpaint the helmet area, which shouldn’t affect any of the image metadata since it’s just replacing pixels.

I unfortunately don’t think I have these images any more – they weren’t the highest quality with the helmet taking up much of the image leading to artefacts. It might be possible to reproduce with multiple takes on a phone camera using the wide angle lens.

Hi!
Can you please give access to your 360 degree images?
I am working on an university project and I need some images as you have used but I am unable to find any from the internet.

I’m about to generate a 3d map of an entire apartment complex but I need lots of ground level photos to go WITH my aerial photos. I was hoping something like this was doable with a 360 camera, but my question is, has anyone figured out a way to import / combine the images from a drone with the equirectangular images from the GoPro on import, or a way to add images after import to increase the quality of the model?

FYI I wrote https://www.openstreetmap.org/user/tordans/diary/401804 to further talk about the possibilities to scale this pipeline.

In reply to Seth Deegan. That's brilliant! I'll add a link to that repo into the article.

I have created a tool to do this for Insta360 cameras: https://github.com/lectrician1/Insta360-2-ODM

In reply to Tobias. That's a good point - looks like a great use case for small crossings. I haven't yet come across any tools for converting a 3D model to an orthophoto - are you aware of any? I know OpenDroneMap does it behind the scenes but doesn't provide an API for it yet. I've wanted to generated oblique orthophotos for some time and there's some talk of tinkering with the model to image code: https://github.com/OpenDroneMap/ODM/issues/1549 This comment appears to show how OpenDroneMap generates the orthophoto from the model: https://community.opendronemap.org/t/creating-2-5d-oblique-orthophoto/13579/4

I was just reminded by https://twitter.com/lars_schwarz/status/1611011065776578560 that the Polycam App https://poly.cam/ can also create a 3D Model. That would only work for small areas, but might be feasible to get detailed data on Crossings etc. to map in OSM.
One would need a process to transform the 3D model to a OpenAerialMap-“Aerial image”, though. And this will probably need manual steps to “orient” the image on the globe.
