ODM: A Python repository from kevinliupy

An open source command line toolkit for processing aerial drone imagery. ODM turns simple 2D images into:

Classified Point Clouds
3D Textured Models
Georeferenced Orthorectified Imagery
Georeferenced Digital Elevation Models

The application is available for Windows, Mac and Linux and it works from the command line, making it ideal for power users, scripts and for integration with other software.

If you would rather not type commands in a shell and are looking for a friendly user interface, check out WebODM.

Quickstart

The easiest way to run ODM is via docker. To install docker, see docs.docker.com. Once you have docker installed and working, you can run ODM by placing some images (JPEGs or TIFFs) in a folder named “images” (for example C:\Users\youruser\datasets\project\images or /home/youruser/datasets/project/images) and simply run from a Command Prompt / Terminal:

# Windows
docker run -ti --rm -v c:/Users/youruser/datasets:/datasets opendronemap/odm --project-path /datasets project

# Mac/Linux
docker run -ti --rm -v /home/youruser/datasets:/datasets opendronemap/odm --project-path /datasets project

You can pass additional parameters by appending them to the command:

docker run -ti --rm -v /datasets:/datasets opendronemap/odm --project-path /datasets project [--additional --parameters --here]

For example, to generate a DSM (--dsm) and increase the orthophoto resolution (--orthophoto-resolution 2) :

docker run -ti --rm -v /datasets:/datasets opendronemap/odm --project-path /datasets project --dsm --orthophoto-resolution 2

Viewing Results

When the process finishes, the results will be organized as follows:

|-- images/
    |-- img-1234.jpg
    |-- ...
|-- opensfm/
    |-- see mapillary/opensfm repository for more info
|-- odm_meshing/
    |-- odm_mesh.ply                    # A 3D mesh
|-- odm_texturing/
    |-- odm_textured_model.obj          # Textured mesh
    |-- odm_textured_model_geo.obj      # Georeferenced textured mesh
|-- odm_georeferencing/
    |-- odm_georeferenced_model.laz     # LAZ format point cloud
|-- odm_orthophoto/
    |-- odm_orthophoto.tif              # Orthophoto GeoTiff

You can use the following free and open source software to open the files generated in ODM:

.tif (GeoTIFF): QGIS
.laz (Compressed LAS): CloudCompare
.obj (Wavefront OBJ), .ply (Stanford Triangle Format): MeshLab

Note! Opening the .tif files generated by ODM in programs such as Photoshop or GIMP might not work (they are GeoTIFFs, not plain TIFFs). Use QGIS instead.

API

ODM can be made accessible from a network via NodeODM.

Documentation

See http://docs.opendronemap.org for tutorials and more guides.

Forum

We have a vibrant community forum. You can search it for issues you might be having with ODM and you can post questions there. We encourage users of ODM to partecipate in the forum and to engage with fellow drone mapping users.

Snap Package

ODM is now available as a Snap Package from the Snap Store. To install you may use the Snap Store (available itself as a Snap Package) or the command line:

sudo snap install opendronemap

To run, you will need a terminal window into which you can type:

opendronemap

# or

snap run opendronemap

# or

/snap/bin/opendronemap

Snap packages will be kept up-to-date automatically, so you don't need to update ODM manually.

WSL or WSL2 Install

Note: This requires that you have installed WSL already by following the instructions on Microsoft's Website.

You can run ODM via WSL or WSL2 by downloading the rootfs.tar.gz file from the releases page on GitHub. Once you have the file saved to your Downloads folder in Windows, open a PowerShell or CMD window by right-clicking the Flag Menu (bottom left by default) and selecting "Windows PowerShell", or alternatively by using the Windows Terminal from the Windows Store.

Inside a PowerShell window, or Windows Terminal running PowerShell, type the following:

# PowerShell
wsl.exe --import ODM $env:APPDATA\ODM C:\path\to\your\Downloads\rootfs.tar.gz

Alternatively if you're using CMD.exe or the CMD support in Windows Terminal type:

# CMD
wsl.exe --import ODM %APPDATA%\ODM C:\path\to\your\Downloads\rootfs.tar.gz

In either case, make sure you replace C:\path\to\your\Downloads\rootfs.tar.gz with the actual path to your rootfs.tar.gz file.

This will save a new Hard Disk image to your Windows AppData folder at C:\Users\username\AppData\roaming\ODM (where username is your Username in Windows), and will set-up a new WSL "distro" called ODM.

You may start the ODM distro by using the relevant option in the Windows Terminal (from the Windows Store) or by executing wsl.exe -d ODM in a PowerShell or CMD window.

ODM is installed to the distro's /code directory. You may execute it with:

/code/run.sh

Updating ODM in WSL

The easiest way to update the installation of ODM is to download the new rootfs.tar.gz file and import it as another distro. You may then unregister the original instance the same way you delete ODM from WSL (see next heading).

Deleting an ODM in WSL instance

wsl.exe --unregister ODM

Finally you'll want to delete the files by using your Windows File Manager (Explorer) to navigate to %APPDATA%, find the ODM directory, and delete it by dragging it to the recycle bin. To permanently delete it empty the recycle bin.

If you have installed to a different directory by changing the --import command you ran to install you must use that directory name to delete the correct files. This is likely the case if you have multiple ODM installations or are updating an already-installed installation.

Native Install (Ubuntu 20.04)

You can run ODM natively on Ubuntu 20.04 LTS (although we don't recommend it):

Download the source from here
Run bash configure.sh install
Download a sample dataset from here (about 550MB) and extract it in /datasets/aukerman
Run ./run.sh --project-path /datasets odm_data_aukerman

Updating a native installation

When updating to a newer version of ODM, it is recommended that you run

bash configure.sh reinstall

to ensure all the dependent packages and modules get updated.

Build From Source

If you want to rebuild your own docker image (if you have changed the source code, for example), from the ODM folder you can type:

docker build -t my_odm_image --no-cache .

When building your own Docker image, if image size is of importance to you, you should use the --squash flag, like so:

docker build --squash -t my_odm_image .

This will clean up intermediate steps in the Docker build process, resulting in a significantly smaller image (about half the size).

Experimental flags need to be enabled in Docker to use the --squash flag. To enable this, insert the following into the file /etc/docker/daemon.json:

{
   "experimental": true
}

After this, you must restart docker.

Developers

Help improve our software! We welcome contributions from everyone, whether to add new features, improve speed, fix existing bugs or add support for more cameras. Check our code of conduct, the contributing guidelines and how decisions are made.

For Linux users, the easiest way to modify the software is to make sure docker is installed, clone the repository and then run from a shell:

$ DATA=/path/to/datasets ./start-dev-env.sh

Where /path/to/datasets is a directory where you can place test datasets (it can also point to an empty directory if you don't have test datasets).

Run configure to set up the required third party libraries:

(odmdev) [user:/code] master+* ± bash configure.sh reinstall

You can now make changes to the ODM source. When you are ready to test the changes you can simply invoke:

(odmdev) [user:/code] master+* ± ./run.sh --project-path /datasets mydataset
