Getting Bundler and friends running — part deux

In my previous post on Getting Bundler and friends running, I suggested how to modify an existing script to get Bundler and other structure from motion parts/pieces up and running.  Here’s my follow up. Install Vagrant and VirtualBox. Download (or clone) this repo: https://github.com/OpenDroneMap/odm-vagrant Navigate into the cloned or unzipped directory (on the command line), run vagrant up Go have a cup of coffee. Come … Continue reading Getting Bundler and friends running — part deux

Getting Bundler and friends running

Anyone who has jumped down the rabbit hole of computer vision has run into dependency h*ll getting software to run.  I jumped down that hole again today with great success that I don’t want to forget (these directions are for Ubuntu, fyi). First, clone BundlerTools: https://github.com/qwesda/BundlerTools This will download and compile (almost) everything for you, which is a wonderful thing.  The one exception is graclus.  … Continue reading Getting Bundler and friends running

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

Big d@mn post: 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

Photogrammetry using Bundler, PMVS, GDAL, and PostGIS.

Photogrammetric like ortho-photos rendered with GDAL/PostGIS from 3D point clouds created in Bundler and PMVS?  Yes indeedeedoo: Point cloud in meshlab:   And “orthophoto” derived from voronoi polygons in PostGIS, rendered to tif with gdal:     Hat tip to my3dscanner for making it so easy to generate the point cloud.  More on this later.
