Mapping animal exhibits using OpenDroneMap: orangutan space estimation for the win.

Conservation and Research A little while back, Charles Ritzler, a PhD student with Case Western Reserve University and employee of Cleveland Metroparks Zoo reached out to me. Charles works with Dr. Kristen Lukas, our Director of Conservation and Research, and as such, his work focuses on improving (quoting Dr. Lukas page) “scientific animal management” and “research on the behavior, health, and welfare” of vertebrate species … Continue reading Mapping animal exhibits using OpenDroneMap: orangutan space estimation for the win.

Old flight meet new flight: Using digital surface models for safer drone flights

Much like the early days of GPS/GNSS, the longer we have drones in the air, the more capacity we build and layer upon previous work. To that end, a colleague of mine has a request to gather video and stills over an area slated for possible installation of a zip line. The request includes flying the path of future zipline. I had concerns whether we … Continue reading Old flight meet new flight: Using digital surface models for safer drone flights

🌿GRASS is everything❤️‍🔥 (or using GRASS GIS to build elevation models in cities)

In the early days of OpenDroneMap, Dakota Benjamin and I discussed the possibility of integrating GRASS into OpenDroneMap to unlock more approaches for processing and post-processing data. We didn’t pull the trigger at that time, in part due to concerns about expanding the universe of dependencies, but later Piero Toffanin added GRASS to WebODM, and we haven’t looked back. Other libraries and tools at the … Continue reading 🌿GRASS is everything❤️‍🔥 (or using GRASS GIS to build elevation models in cities)

A new era of open source funding? How we raised $5,099 for core work. — OpenDroneMap

As part of our mission to bring awesome drone software, we focus intensively on sustainability (a.k.a. how to pay for development, bug fixes, new features, hosting, etc. for the benefit of all). Open-source is a tricky type of software to fund. I will not cover the details, as other people have already done a great… A new era of open source funding? How we raised $5,099 … Continue reading A new era of open source funding? How we raised $5,099 for core work. — OpenDroneMap

Scanning the samples with OpenDroneMap — part II

In a previous post, we did a bit of a proof of concept in using OpenDroneMap for scanning a skull. It was the second skull I had scanned with OpenDroneMap. The first was a mountain gorilla skull from the Virungas from the 1920s that I then printed in 3D and brought home with me to Rwanda on a recent trip. These previous scans though were … Continue reading Scanning the samples with OpenDroneMap — part II

Beyond Data

I think of data from photogrammetry as a pipeline problem in which we have just begun to address the beginning of the pipeline. Historically, photogrammetry was the purview of a few (and depending on where you are in the world, laws may make it still so), dependent upon expensive software, even more expensive hardware (think: calibrated camera >$400k, cesna ~$130k, IMU ~$25k, plus fuel etc. … Continue reading Beyond Data

Scanning the samples with OpenDroneMap

In previous posts, we’ve scanned whole cities, cliff faces, down to small things like ukuleles and tiny pits to identify difficult to identify plants. This post goes in a slight different direction, doing a bit of a meta-scan of another kind of voucher: animal bones. I wanted to figure out what other interesting use cases there are for OpenDroneMap. For example, could we use it … Continue reading Scanning the samples with OpenDroneMap

3D Reconstructing… everything, part cinq: the beginnings of 3D construction

In previous posts in this series here and here II and here III here IV, we’ve worked through a surprising use case in OpenDroneMap: unreferenced imagery for general 3D reconstruction. Let us take this one step further toward 3D construction. If we have a model that we can georeference (✔️) and thus can do things like create contours (✔️) then maybe we can use these … Continue reading 3D Reconstructing… everything, part cinq: the beginnings of 3D construction
