DVS Reconstruction

This repository provides software for our publication "Real-Time Intensity-Image Reconstruction for Event Cameras Using Manifold Regularisation", BMVC 2016.

If you use this code please cite the following publication:

Compiling

For your convenience, the required libraries that are on Github are added as submodules. So clone this repository with --recursive or do a

git submodule update --init --recursive

after cloning.

This software requies:

• GCC >= 4.9
• CMake >= 3.2
• Qt >= 5.6
• ImageUtilities (https://github.com/VLOGroup/imageutilities) with the iugui, iuio and iumath modules
• libcaer >=2.0 (https://github.com/inilabs/libcaer)
• cnpy (https://github.com/rogersce/cnpy)
• DVS128 or DAVIS240 camera (can also load events from files)

To compile, first build and install ImageUtilities, then:

cd cnpy
cmake .
make
(sudo) make install
cd ../libcaer
cmake .
make
(sudo) make install
cd ..
mkdir build
cd build
cmake ../src
make -j6

Per default, the application will compile to support the iniLabs DVS128. If you want to attach a DAVIS240 instead, set the CMake option WITH_DAVIS.

Usage

Launch live_reconstruction_gui to get to the main application which should look like this: Clicking on the play button with an attached camera will start the live reconstruction method. Alternatively, events can be loaded from text files with one event per line:

<timestamp in seconds> <x> <y> <polarity (-1/1)>
...
