Requirements

Software was developed and tested on LINUX UBUNTU 14.04, 16.04 with following libraries OpenGL, GLUT, PCL 1.5, CUDA>=7.5

Build

Each lesson is an independent software package, thus the following steps should be performed:

cd lesson_X
mkdir BUILD
cd BUILD
cmake -DCMAKE_BUILD_TYPE=Release ..
make
./lesson_X

Use Cases

fastSLAM

This DEMO shows the parallel computing for fastSLAM. Each particle containes 3D map built based on registered Velodyne VLP16 3D semantic data. The result is corrected trajectory.

Execute

Run ./fastSLAM and read instructions in console

to run example

./fastSLAM ../dataset/model_reduced_pointXYZIRNL.xml

(check help in console, e.g. type c to start computations, software was tested on GF1050Ti, thus for this example the single scan calculation takes up to 40ms)

Particle filter localization

This DEMO shows the use of GPU for robust robot localization based on 3D semantic data.

Execute

Run ./particle_filter_localization_fast and read instructions in console

to run example

Run ./particle_filter_localization_fast ../dataset/metascan_pointXYZL.pcd ../dataset/odom_and_pointXYZL.xml

(check help in console, e.g. type i to start computations, software was tested on GF1050Ti, thus for this example the single particle filter calculation takes up to 50ms)
