Exciting project and I'm a proponent. I'm curious about privacy aspects and how they're are handled. I didn't see anything in my cursorily glance at the website.

For example if neighbor complains about their land being mapped. I don't even know if it's a justifiable complaint. I'm sure it depends on the local laws.

I guess my question is, how is this project (or drone pilots) going to defend against lawsuits. (if they occur) (seems inevitable)

OpenDroneMap co-founder here: happy to see this on HN and to answer any questions.

Very cool! I noticed AGPL 3 License, do you offer licensing options if folks want to host this integrated with other closed source code? Or would it be permissible to create a "microservice" with ODM only that closed source software can use API calls to contact?

We do not offer other licensing options. We encourage people and organizations to create services that leverage ODM, closed or open, while respecting the terms of the AGPL.

This is (mostly) governed by the FAA and their license granted to drone pilots [1]. Your concerns are also touched on by the FAA during the training [2]. Please consider that plenty of smart people have considered these same things before you comment.

What sort of setups does this support? What drone models and firmware? What sort of cameras are supported? Quads? Fixed? DJI? Betaflight? Ardupilot? Does it need a camera with a gimbal?

Pretty much any camera (even multiple cameras), from any orientation (no gimbal required). Also works with your cellphone camera or DSLR camera. Just try not to change the focus between shots too much. DJI models are well supported.

Wanted to share a personal project I've been working on using ODM. I'm mostly on a weekly basis capturing the progress of my home as it is built. I have a DJI Mini 2 and using Dronelink to create the missions. I was originally using DJI Flight Planner + Litchi but it's paths it was generating for the area I wanted to cover wasn't great and it forced my gimble to look straight down, I'm sure Litchi may have let me adj…

Lovely! Try bumping --mesh-octree-depth by 1 or 2 for sharper models. Also if you're capturing photos in motion, definitely enable --rolling-shutter which will help compensate for the rolling shutter distortion of the DJI Mini 2's camera (it will take a bit longer to process though).

How does it compensate for rolling shutter? Out of curiosity :)

I've been trying to get my organization to use ODM, but finding it difficult. The problem is analogous to the issues that Gimp has to Photoshop or Linux to Windows -- ease of use. Additionally, even if you properly configure the software the quality still is not comparable to the big proprietary players in the photogrammetry field: Bentley Systems; Pix4D; Drone Deploy. A major reason for the quality issues is that th…

> A major reason for the quality issues is that the major drone manufacturers work directly with the proprietary photogrammetry software providers in the field to optimize the algorithms to their drones.

Would you care to elaborate? My belief is that all the photogrammetry engine wants is that the drone manufacturer does as few processing as possible on the images, in order to not alter the geometry. I don't see what kind of algorithms coming from the drone manufacturer would help, and therefore I don't see how that's a problem for ODM.

Are DJI models the only ones supported?

It implements the method outlined in "A two-step approach for the correction of rolling shutter distortion in UAV photogrammetry" by Y. Zhou and others: https://www.sciencedirect.com/science/article/abs/pii/S09242...

The Python code is probably easier to understand: https://github.com/OpenDroneMap/OpenSfM/blob/287/opensfm/act...

his question seemed clear and reasonable to me, which you answered well, minus your comment in the final sentence.
