Apparently travelling for 20 days straight back and forth through 3 time zones across 13 hours of time difference makes me calmer, more rational, and a better presenter than normal. All 27 minutes and 35 seconds. And then don’t forget to check out the rest: http://vimeo.com/foss4g Continue reading OpenDroneMap — The MOVIE
Current scene in the smathermather household — OpenDroneMap sneakernet packets being produced for training 53 people in OpenDroneMap on Monday. (Yes, I’m using rsync, not tar. Old dog. New tricks.) edit: let’s throw some code up there, ugly though it may be: Continue reading OpenDroneMap and the art of sneakernet packet making
I consider myself an artist and scientist. I’ll confess I have let the art go fallow some in recent years, but these are two sides of one coin. If you like either, and especially if you like both, you should check out Tobias Research. I met Michele at FOSS4G, where from the moment she saw my presentation on OpenDroneMap to using it to create a … Continue reading OpenDroneMap — Art and Science
This past Friday at FOSS4G in Portland, I announced the (early) release of OpenDroneMap, a software toolchain for civilian (and humanitarian?) UAS/UAV image processing. The software is currently a simple fork of https://github.com/qwesda/BundlerTools, and will process from unreferenced overlapping photos to an unreferenced point cloud. Directions are included in the repo to create a mesh and UV textured mesh as the subsequent steps, but the … Continue reading Announcing OpenDroneMap — Software for civilian (and humanitarian?) UAS post processing
I’ve touched down and started to settle into Tri-Met country not too long after returning from FOSS4G Korea. The public transit is great, the city vibrant with the warmth of a small town, and the energy of an enclave in a big city, and it’s also slightly surreal, now that I’m back where I am no longer, as Paul Ramsey put it, functionally illiterate. Functionally … Continue reading From Dobongsan to Mount Saint Helens — FOSS4Gs and OpenDroneMap
I have been contemplating all sorts of varied uses of Structure from Motion techniques. One of those outputs, in addition to using sUAVs (drones) is just to orthorectify and generate 3D meshes from ordinary photos. This has really great potential for linear assets like streams and rivers, trails and roads. We’ll have to being to contemplate how we’ll use (and summarize!) the incredible amount of … Continue reading Inventorying linear assets– really high resolution orthos
A really cool SfM workflow write up: http://wedidstuff.heavyimage.com/ which includes texture mapping (yay!)… . Pic from the end of the workflow: Thanks to Fred Judson for the tip on this one. Continue reading Cool write up on Structure from Motion (SfM)
In my previous post, https://smathermather.wordpress.com/2014/02/04/big-dmn-post-photogrammetrically-derived-point-clouds/, I briefly cover software for creating photogrammetrically derived point clouds. I didn’t summarize, like this, but PDPCs can be created in three easy steps: Structure from Motion for unordered image collections Clustering Views for Multi-view Stereo Multi-view stereo (dense point cloud reconstruction) But, unfairly, I gloss over some of the complications of creating meaningful data from PDPC processing. Truth told, … Continue reading Short follow up: Photogrammetrically Derived Point Clouds
I chatted with Howard Butler (@howardbutler) today about a project he’s working on with Uday Verma (@udayverma @udaykverma) called Greyhound (https://github.com/hobu/greyhound) a pointcloud querying and streaming framework over websockets for the web and your native apps. It’s a really promising project, and I hope to kick the tires of it really soon. The conversation inspired this post, which I’ve been meaning to do for a … Continue reading Big d@mn post: Photogrammetrically Derived Point Clouds
Just an image today. Continue reading Drone Pointilism
