NodeMICMAC

NodeMICMAC is a Node.js App and REST API to access MicMac. It exposes an API which is used by WebODM or other projects. This project is sponsored and developed by DroneMapper. This repository was originally forked from NodeODM, which is part of the OpenDroneMap Project.

Project Status

This list is not by order of importance.

Note: This project currently creates a geo-referenced DEM and Ortho from our 4th Ave. test imagery (and most likely your imagery). The results are located in their respective directories in UTM projection.

Mission Planning / Execution

We recommend using a mission planning application such as MapPilot, DJI GS Pro, or Pix4DMapper.

Support

Commercial support for this project is available from DroneMapper.com.

Getting Started

We recommend that you setup NodeMICMAC using Docker.

Docker image build:

docker build -t dronemapper/node-micmac .

From the Docker Quickstart Terminal (Windows / OSX) or from the command line (Linux) type:

docker run -p 3000:3000 dronemapper/node-micmac

If you're on Windows/OSX, find the IP of your Docker machine by running this command from your Docker Quickstart Terminal:

docker-machine ip

Linux users can connect to 127.0.0.1.

Open a Web Browser to http://<yourDockerMachineIp>:3000
Load some images with geo-tags
Press "Start Task"
Go for a walk or enjoy a pastis! :)

If the computer running NodeMICMAC is using an old or 32bit CPU, you need to compile OpenDroneMap from sources and setup NodeMICMAC natively. You cannot use docker. Docker images work with CPUs with 64-bit extensions, MMX, SSE, SSE2, SSE3 and SSSE3 instruction set support or higher. Seeing a Illegal instruction error while processing images is an indication that your CPU is too old.

Using Ground Control Points

For GCP processing, you will need to include two files in txt format. Examples of the files are shown below.

The files should be space delimited and can be named anything, as long as 3D exists in the ground filename and 2D exists in the images filename.

You can substitute the 2 GCP files above for a single GCP file that matches ODM format and is named gcp_list.txt. Below is an example of ODM format:

API Docs

See the ODM API Documentation Page.

Run Tasks from the Command Line

You can use CloudODM to run tasks with NodeMICMAC from the command line. (Untested)

Using an External Hard Drive (Not Recommended/Performance IO Reasons)

If you want to store results on a separate drive, map the /var/www/data folder to the location of your drive:

docker run -p 3000:3000 -v /mnt/external_hd:/var/www/data dronemapper/node-micmac

This can be also used to access the computation results directly from the file system.

Run it Natively

If you are already running ODM on Ubuntu natively you can follow these steps:

You may need to step through the Dockerfile and install missing dependencies listed there to install natively.

1] Install PotreeConverter and LASzip dependency

apt-get install -y libboost-dev libboost-program-options-dev exiftool

pip install Shapely
pip install utm

mkdir /staging
git clone https://github.com/pierotofy/LAStools /staging/LAStools
cd LAStools/LASzip
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

git clone https://github.com/pierotofy/PotreeConverter /staging/PotreeConverter
cd /staging/PotreeConverter
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DLASZIP_INCLUDE_DIRS=/staging/LAStools/LASzip/dll -DLASZIP_LIBRARY=/staging/LAStools/LASzip/build/src/liblaszip.a ..
make && sudo make install

2] Install gdal2tiles.py script, node.js and npm dependencies

sudo curl --silent --location https://deb.nodesource.com/setup_6.x | sudo bash -
sudo apt-get install -y nodejs python-gdal
git clone hhttps://github.com/dronemapper-io/NodeMICMAC.git
cd NodeMICMAC
npm install

3] Start NodeMICMAC

nodejs index.js

Use odm_path

nodejs index.js --odm_path /home/projects/NodeMICMAC/dm/

For other command line options you can run:

nodejs index.js --help

You can also specify configuration values via a JSON file:

nodejs index.js --config config.default.json

Command line arguments always take precedence over the configuration file.

Run it using PM2

The app can also be run as a background process using the pm2 process manager, which can also assist you with system startup scripts and process monitoring.

To install pm2, run (using sudo if required):

npm install pm2 -g

The app can then be started using

pm2 start processes.json

To have pm2 started on OS startup run

pm2 save
pm2 startup

and then run the command as per the instructions that prints out. If that command errors then you may have to specify the system (note that systemd should be used on CentOS 7). Note that if the process is not running as root (recommended) you will need to change /etc/init.d/pm2-init.sh to set export PM2_HOME="/path/to/user/home/.pm2", as per these instructions

You can monitor the process using pm2 status.

Test Mode

If you want to make a contribution, but don't want to setup OpenDroneMap or MICMAC, or perhaps you are working on a Windows machine, or if you want to run automated tests, you can turn test mode on:

node index.js --test

While in test mode all calls to OpenDroneMap/MICMAC's code will be simulated (see the /tests directory for the mock data that is returned).

Test Images

You can find some test drone images here.

What if I need more functionality?

NodeMICMAC is meant to be a lightweight API. Commercial support and development is available.

Contributing

Make a pull request for small contributions. For big contributions, please open a discussion or issue first. Please use ES6 syntax while writing new Javascript code so that we can keep the code base uniform.
