This is a ROS-based online learning framework for human classification in 3D LiDAR scans, taking advantage of robust multi-target tracking to avoid the need for data annotation by a human expert. Please watch the videos below for more details.

For a standalone implementation of the clustering method, please refer to: https://github.com/yzrobot/adaptive_clustering

$ cd catkin_ws/src
// Install prerequisite packages 
$ git clone https://github.com/wg-perception/people.git
$ git clone https://github.com/DLu/wu_ros_tools.git
$ sudo apt-get install ros-kinetic-bfl
// The core 
$ git clone https://github.com/yzrobot/online_learning
// Build
$ cd catkin_ws
$ catkin_make

After catkin_make succeed, modify 'line 3' of online_learning/object3d_detector/launch/object3d_detector.launch, and make the value is the path where your bag files are located:

<arg name="bag" value="/home/yq/Downloads/LCAS_20160523_1200_1218.bag"/>

The bag file offered by Lincoln Centre for Autonomous Systems is in velodyne_msgs/VelodyneScan message type, so we would need related velodyne packages in ROS:

$ sudo apt-get install ros-kinetic-velodyne*

Now, the svm should be able to run:

$ cd catkin_ws
$ source devel/setup.bash
$ roslaunch object3d_detector object3d_detector.launch
