KFusion-TornadoVM

A Java implementation of the Kinect Fusion application running on TornadoVM. It can run on existing datasets as well as in real-time with input frames from an attached RBG-d camera. Detailed explanation and performance evaluation can be found in the following publication.

Output

If you enable the GUI while running KFusion you will see a real-time 3D space reconstruction similar to the image below:

KFusion GUI output

In addition, you will see output text with performance metrics across the frames that KFusion processes:

How to start?

This implementation runs on TornadoVM to achieve GPU acceleration and real-time performance. Hence, you need to install Tornado following the instructions from Tornado-INSTALL

After you successfully build Tornado, you can install KFusion-TornadoVM by issuing the following commands:

Dependencies:
sudo dnf install -y yaml-cpp-devel gtk2-devel mesa-libEGL-devel vtk-devel cmake make git mercurial wget unzip gcc gcc-c++ lapack blas lapack-devel blas-devel findutils cvs glut-devel glew-devel boost-devel glog-devel gflags-devel libXmu-devel

Then install KFUSION-TornadoVM

# Setup:
export KFUSION_ROOT="${PWD}"
export PATH="${PATH}:${KFUSION_ROOT}/bin"
export JAVA_HOME=/path/to/graal/jdk1.8.0_131
export TORNADO_ROOT=/path/to/tornado
export PATH="${PATH}:${TORNADO_ROOT}/bin/bin/"
export TORNADO_SDK=${TORNADO_ROOT}/bin/sdk

## Compile and run KFusion-TornadoVM
$ mvn clean install -DskipTests

## Run KFusion-TornadoVM GUI 
$ kfusion kfusion.tornado.GUI

## Run Benchmarking mode
$ kfusion kfusion.tornado.Benchmark <config file>

How to get the datasets?

KFusion-Tornado uses the ICL-NUIM datasets.<br> We provide a script to automatically download and compose the video files in raw format. <br> Alternatively, when running the Java program (KFusion-TornadoVM) the first time, it will download the corresponding video raw-file and install it locally.

Option a) Automatically

The first time you run the application and if the raw file is not installed locally (~/.kfusion_tornado), then the program will ask you if you want to download it auotmatically:

$ kfusion kfusion.tornado.Benchmark conf/bm-traj3.settings 
KFussion Accelerated with Tornado
	: Reading configuration file: /home/juan/.kfusion_tornado/living_room_traj3_loop.raw
Data Set file does not exist. Do you want to download it automatically? (~2GB) 
Press [yes/no] (default: yes) :

Option b) Manually

Run the downloadDataSets.sh <url> <fileName>, for example:

$ bash downloadDataSets.sh  http://www.doc.ic.ac.uk/~ahanda/living_room_traj2_loop.tgz living_room_traj2_loop.raw

Running KFusion-Tornado

KFusion can run in two modes receiving input from:

  1. RGB-d camera where you select the input source from the drop-down menu:
## Run KFusion-Tornado GUI 
$ kfusion kfusion.tornado.GUI
  1. Pre-defined datasets again through the GUI selection or:
## Run KFusion-Tornado GUI 
$ kfusion kfusion.tornado.Benchmark <config file>

In our examples, we use images from the ICL-NUIM dataset which will be downloaded automatically when issuing the following command:

$ kfusion kfusion.tornado.Benchmark conf/bm-traj2.settings
