OpenDroneMap is a tool to postprocess small Unmanned Aerial Vehicle (sUAS), balloon, kite, and street view data to geographic data. With the current update, we are adding the ability to create orthophotos from drone, balloon, and kite imagery which has GPS ephemeris. Future versions will permit the use of GCPs with no onboard GPS. forked from qwesda/BundlerTools ( https://github.com/qwesda/BundlerTools )

What is it?

OpenDroneMap is a toolchain for processing raw civilian UAS imagery to other useful products. What kind of products?

1. Point Clouds
2. Digital Surface Models
3. Textured Digital Surface Models
4. Orthorectified Imagery
5. Classified Point Clouds
6. Digital Elevation Models
7. etc.

Sadly, it does not do all of this yet. So far, it does step 1: Point Clouds. But outputs 2-4 are on their way shortly, so stay tuned.

Steps to get OpenDroneMap running:

(Requires Ubuntu 12.04 32-bit at this time. May also work with Ubuntu 12.04 64-bit.

(Requires Ubuntu 12.04 or later, see https://github.com/OpenDroneMap/odm_vagrant for running on Windows in a VM)

Run install.sh to build.

./install.sh

From a directory full of your images, run

./run.pl

From Meshlab 1.3.3:

* Open Project file, navigate to:
	* <project_location>/reconstruction-with-image-size-1200/bundle/bundle.out
* It will prompt for the image list file
	* <project_location>/reconstruction-with-image-size-1200/list.txt
* Control-L and delete "0 model"
* Import dense point cloud:
	* e.g. <project_location>/reconstruction-with-image-size-1200-results/option-0000.ply
	* (there may be multiple ply files)
* Make a mesh:
	* Filters:Remeshing, Simplification and Reconstruction:Surface Reconstruction Poisson
* Texture the mesh
	* Parameterization + texturing from registered rasters

Long term, the aim is for the toolchain to also be able to optionally push to a variety of online data repositories, pushing hi-resolution aerials to OpenAerialMap, point clouds to OpenTopography, and pushing digital elevation models to an emerging global repository (yet to be named...). That leaves only digital surface model meshes and UV textured meshes with no global repository home.

Troubleshooting:

If you run ODM with your own camera, it is possible you will see something like this:

  - configuration:
    --cmvs-maxImages: 100
    --end-with: pmvs
    --match-size: 200
    --matcher-ratio: 0.6
    --matcher-threshold: 2
    --pmvs-csize: 2
    --pmvs-level: 1
    --pmvs-minImageNum: 3
    --pmvs-threshold: 0.7
    --pmvs-wsize: 7
    --resize-to: 1200
    --start-with: resize

This means that your camera is not in the database, https://github.com/OpenDroneMap/OpenDroneMap/blob/gh-pages/ccd_defs.pl

This problem is easily remedied. We need to know CCD size in the camera. We'll get these for our Sony Cyber-shot DSC-HX5 from dpreview: http://www.dpreview.com/products/sony/compacts/sony_dschx5/specifications

So, we'll add the following line to our ccd_defs.pl:

 "SONY DSC-HX5V"                            => 6.104,  # 1/2.4"

And so others can use it, we'll do a pull request to add it to our array for everyone else.
