OpenDroneMap — Orthophotos and Textured Mesh (testing…)

A few new features are about to land on OpenDroneMap. Among those features, we have great work led and implemented by Spotscale for orienting our textured meshes so that Z is up: and auto-exporting an orthophoto when GPS ephemeris is available in our input images: ——- Next step — testing the input of ground control points in order to output fully referenced and orthorectified imagery. … Continue reading OpenDroneMap — Orthophotos and Textured Mesh (testing…)

OpenDroneMap — Orthophotos and Textured Mesh (cont.)

(Credit goes to Brandon Garman for the graphic above. It’s part of a very nice sUAS graphic he’s putting together at the moment.) Following up on the earlier post on the addition of orthophotos and textured mesh to OpenDroneMap (FYI, one word, and not OpenDroneMaps) https://smathermather.wordpress.com/2014/12/22/opendronemap-orthophotos-and-textured-mesh/ we have some more features in the pipeline. This is a deeper dive into architecture and future enhancements. In the … Continue reading OpenDroneMap — Orthophotos and Textured Mesh (cont.)

OpenDroneMap — Humanitarian uses of outputs

In response to a recent query about OpenDroneMap, I’m writing a quick summary here, and then a brief write-up on how it could relate to humanitarian response / crisis mapping applications, as discussed in my Deep Dive session at International Conference of Crisis Mappers in New York, this past November.  Ahem. The summary: OpenDroneMap: Open Source Toolkit for processing Civilian Drone Imagery “OpenDroneMap is an … Continue reading OpenDroneMap — Humanitarian uses of outputs

OpenDroneMap — Orthophotos and Textured Mesh

Good news to report, though I haven’t finished my own testing yet… but OpenDroneMap, which previously would just create point clouds from drone images, now also produces: Meshes! Textured meshes! Georeferenced textured meshes (if the exif data has geographic coordinates) Georeferenced orthophotos! (if the exif data has geographic coordinates) Now, I’d like those ifs to go away, but that requires a bit of thoughtful interface … Continue reading OpenDroneMap — Orthophotos and Textured Mesh

OpenDroneMap — The MOVIE

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

OpenDroneMap and the art of sneakernet packet making

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

OpenDroneMap — Art and Science

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

Announcing OpenDroneMap — Software for civilian (and humanitarian?) UAS post processing

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?)

From Dobongsan to Mount Saint Helens — FOSS4Gs and OpenDroneMap

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

Short follow up: Photogrammetrically Derived Point Clouds

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
