PSES Kinect Utilities

This ROS-package provides some utilities to cope with the noisy and dense data of the kinect and to perform efficiently some useful conversions such as depth image to point cloud or point cloud to laserscan.

Prerequisites

This project was build with ROS Kinetic but should work on older ROS versions as well. In addition to that, this project depends on the ROS packages cv_bridge, pcl_ros and tf2_sensor_msgs. You will need to install them, if they are not already installed in your system. More about that in a moment.

Installing

Clone the repo into your ROS src folder:

cd ~/catkin_ws/src

git clone https://github.com/tud-pses/pses_kinect_utilities.git

cd ..

Install all dependencies of the package:

rosdep install pses_kinect_utilities

Build the package with catkin_make:

catkin_make

Getting Started

Screenshots

Here are some screenshots from our toolkit: Original color image delivered by the kinect2_bridge

Original depth image delivered by the kinect2_bridge

Point cloud computed and published by our package

Note: We implemented our own point cloud conversion, which is performed on the GPU using a opencl kernel. Therefore it is more efficient and faster than the pointcloud delivered by the kinect2_bridge or the package depth_image_proc
