2nd day of the OSM Mali OpenDroneMap training went as well or better than the first. We spent quite a bit of time looking at the products of OpenDroneMap from day one, culminating in exploring their use in blender, and discussion of their use in JOSM, iD, and QGIS. We also got out for some field mapping. Lacking the necessary permits for flights, we tried … Continue reading Moar OSM Mali
It’s a trite but we’ll earned pun. OSM Mali is amazing. I am in Bamako this week doing an OpenDroneMap workshop, and the community here is incredible. We just completed the first day of a two day workshop, working through some photogrammetry introductions, and on to some proper mapping tomorrow. For this round, we weren’t able to fly just yet, so we are working around … Continue reading Awesome Mali
In previous posts, we’ve scanned whole cities, cliff faces, down to small things like ukuleles. Such work is getting some to claim that the project needs renamed. Maybe… : Now, for a new problem space: plant identification. The background There are a few challenging plant groups to identify in the US. Among the ones I heard about in freshman biology: sedges (think: like grasses but … Continue reading Scanning the world with OpenDroneMap or Ne’er cast a cloot til Mey’s oot
WebODM introduced support for plant health algorithms about a month ago. It was no secret that we concurrently started work to support TIFFs file inputs and multispectral cameras, both features that have been highly requested. We are excited to announce the release of ODM 0.9.8, which adds novel features as well as bringing significant improvements!… ODM 0.9.8 Adds Multispectral, 16bit TIFFs Support and Moar! — OpenDroneMap Continue reading ODM 0.9.8 Adds Multispectral, 16bit TIFFs Support and Moar! — OpenDroneMap
Introduction I had an interesting question recently at a workshop: “What parameters do you use for OpenDroneMap?” Now, OpenDroneMap has a lot of configurability, lots of different parameters, and it can be difficult to sift through to find the right parameters for your dataset and use case. That said, the defaults tend to work pretty… Choosing good OpenDroneMap parameters — OpenDroneMap Continue reading Choosing good OpenDroneMap parameters — OpenDroneMap
Let us explore a little more deeply the opportunity for drone photogrammetry for documenting deciduous forests. In previous posts, we explored exactly how, under the right conditions, we can see through leaf-off forest to the terrain below in ways that are quite favorable relative to techniques like lidar: But a side effect of this capacity, is resolution and reconstructions that reconstruct all of the standing … Continue reading Seeing the trees and the forest
Thanks to the tireless work of the folks behind the Zanzibar Mapping Initiative, I have been exploring the latest settings in OpenDroneMap for processing data over Stone Town. I managed to get some nice looking orthos from the dataset… https://smathermather.com/2020/01/15/stone-town-digital-surface-model/ After a few days of mapping the very small 🎸, let’s go back to a city scale, and back to Zanzibar. In the previous post, … Continue reading Stone Town Digital Surface Model — Part Two
In previous posts in this series here and here II and here III: , we’ve worked through a surprising use case in OpenDroneMap: unreferenced imagery for general 3D reconstruction. To get there, we eventually included ground control in the form of a coordinate system set by a builder’s square set in the scene. (Fair warning, I did find a bug in the automated calculation of … Continue reading 3D Reconstructing… everything, part quatre: a fully referenced ukulele
This test extends to using full resolution 50MP images for reconstruction. I can’t fly the big camera yet, but I can test it on smaller things, and make sure we are ready with OpenDroneMap 3D reconstruction done in OpenDroneMap; 3D rendering done in blender; gif generated in Gimp. Continue reading 3D Reconstructing… everything, part deux
I am just posting some quick snapshots of my tests with reconstructing smaller things, like this ukelele, with OpenDroneMap. This was also a test of using OpenDroneMap with 50MP imagery, something which as recently as a year ago didn’t work very well. Continue reading 3D Reconstructing… everything (in this case, a Ukulele)
