[ROS Tutorials] ROS Perception Unit2# Follow Line with OpenCV (Python)

Learn about OpenCV in ROS with a following line Kobuki.
In this unit, you will learn how to start using the most basic and also the most powerful tool for perception in ROS: OpenCV. OpenCV is the most extensive and complete library for image recognition. With it, you will be able to work with images like never before: applying filters, postprocessing, and working with images in any way you want.

[ About the Courses ]
Perception is probably one of the most important things when we talk about autonomy.
In this course you will learn how perception is performed by robots using the ROS Framework.

[ What you will learn ]
At the end of this course you will fell comfortable about making robots do the following things:
- Track objects by its color blobs
- Navigate following floor lines with only RGB camera
- Detect human faces and track them
- Recognize different faces
- Track a person through a 3D environment
- Recognize flat surfaces like tables where object might be placed
- Recognize objects and track them in 3D space with PointCloudSensors

[ How will you learn all this? ]
All Robot Ignite Courses are based on hands-on learning because we have experienced that it is the best and fastest way to learn about robotics.
That's why to learn all the above mentioned topics, you will work with different robots and environments.
You will work with:
- Mira Robot for Blob Tracking
- TurtleBot for line following
- Fetch Robot for people and object tracking, and detection in different environments.
- Aibo Robot for the Final Project

[ Robots Used in this course ]
- Mira Robot
- Turtlebot
- Fetch
- Fetch2
- Aibo

[ Requirement ]
- A laptop and internet connection. No required installation, compilation, specific computer.
- Basic knowledge of Python
- Have done the Courses for ROS Basics (http://www.theconstructsim.com/construct-learn-develop-robots-using-ros/robotigniteacademy_learnros/ros-courses-library/ros-courses-ros-basics-in-5-days-c/?utm_source=youtube&utm_medium=tutorial&utm_campaign=ukGa74saFfM), TF (http://www.theconstructsim.com/construct-learn-develop-robots-using-ros/robotigniteacademy_learnros/ros-courses-library/tf-ros-101/?utm_source=youtube&utm_medium=tutorial&utm_campaign=ukGa74saFfM) and URDF (http://www.theconstructsim.com/construct-learn-develop-robots-using-ros/robotigniteacademy_learnros/ros-courses-library/robot-creation-with-urdf/?utm_source=youtube&utm_medium=tutorial&utm_campaign=ukGa74saFfM)
