ROS package for obstacle segmentation in a point cloud scene

Obstacle_processor

ROS package for obstacle segmentation in a point cloud scene.

Installation

• Before you install the package, you have to configure your RGB-D sensor and calibrate it. You can also run this package offline i.e. streaming point cloud ROS topic from .bag file.
• Clone the repository inside src/ directory of your catkin workspace

mkdir obstacle_processor
cd obstacle_processor/
git clone name_of_repository

• Run CMake to compile source code

catkin_make

• Source your workspace

source catkin_ws/devel/setup.bash

• Setup your robot platform on a ground and remove the all objects in front of it for calibration purposes and run calibration node

roslaunch obstacle_processor calibration.launch

• Now you can run obstacle_processor detection algorithm by either of 5 launch commands (two last commands launch obstacle_processor_node along with kinect2_bridge package from iai_kinect2 package, but can be replaced for whatever bridge package compatible with your RGB-D sensor that produces point cloud ROS topic)

roslaunch obstacle_processor obstacle_processor.launch

or

roslaunch obstacle_processor obstacle_processor_rviz.launch

or

roslaunch obstacle_processor obstacle_processor_rviz_debug.launch

or

roslaunch obstacle_processor obstacle_processor_launch_all.launch

or

roslaunch obstacle_processor obstacle_processor_launch_all_rviz.launch

obstacle_processor's Issues

Program stuck after gdb run

I am using Intel RealSense to get point clouds instead of LiDAR. I changed the topic that the node's subscriber subscribes to RealSense's point cloud topic. After I launch the package and typing 'run' into the gdb terminal, I get the following warning "couldn't register subscriber on topic[/]". Nothing happens after that.

Could you let me know what could be the issue?
