LSD-SLAM: Large-Scale Direct Monocular SLAM

LSD-SLAM is a novel approach to real-time monocular SLAM. It is fully direct (i.e. does not use keypoints / features) and creates large-scale, semi-dense maps in real-time on a laptop. For more information see http://vision.in.tum.de/lsdslam where you can also find the corresponding publications and Youtube videos, as well as some example-input datasets, and the generated output as rosbag or .ply point cloud.

How to build from source

The lsd slam code requires c++11 features. Thus, it needs c++11 supported compiler to build the code from source.

Windows (requiring Visual Studio 2013)

For windows build, please follow instructions from Windows build

Android (requiring gcc4.7+)

TBA

Linux (requiring gcc4.7+)

Building under Ubuntu

1. Install G2O

2. Install G2O debug versions of the lib

   a. run the following inside the build folder so debug is enabled and the libs build accordingly

   cmake -DCMAKE_BUILD_TYPE=Debug .. 
   make
   sudo make install
   

3. under lsd_slam source, create a folder mkdir build

4. cd build

5. cmake ..

6. make -j4

This will build lsd_slam as a lib and also build the sample_app under LSD_SLAM_SOURCE/bin

Run the sample with

LSD_SLAM_SOURCE/bin/sample_app <video device id>

eg., to run with the video device /dev/video0

LSD_SLAM_SOURE/bin/sample_app 0
