ROS RViz Advanced Markers Python
Learn how to use RViz Advanced Markers for debugging and visualization
Visualizing data in the correct way is vital to extract meaningful conclusions. This is especially true in Robotics.
One of the problems you always tend to have in robotics is knowing what the robot is actually seeing, what is the virtual representation of the world in his mind. It’s also very important to represent visually complex data in one place only.
That’s why RViz and all its markers and plugins have made robotics more user friendly and powerful than ever before!
- Understand how to use Basic RViz Markers.
- Create Bounding Box Arrays that change dynamically.
- Add Overlay text, graphs, and menus in RViz.
- Draw TFTRajectories, RobotFootsteps, and occupancy grids that change based on real robot data.
- Draw pictograms from FontAwsome to represent detections and real objects in the world
- Represent TwistStamped commands issued to the robot
- Create Interactive displays in RViz that allow the execution of programs from RViz with custom icons.
- Record videos of RViz
