i have a turtlebot3 and i want to make it follow the black line on a white line map. I have the raspberry Pi camera interface, but i do not know where to set up the programming or how to set the camera to track it. essentially i need a how to guide on how to make it follow the line. is there any tutorial on how to acheive this?

it has a raspberry Pi 3, Raspberry Pi camera interface Ubuntu 16.04 and UBUNTU Mate ROS Kinetic

i know i need the camera to differentiate between the line and the white space, and translate those measurements relative to the bot. any tutorials or code would be appreciated.

Start with ROS tutorials: https://wiki.ros.org/ROS/Tutorials

Then take a look at OpenCV tutorials:

General guidelines:

Get the image from the camera and display it in RViz
Set up a package that uses OpenCV to process the image
Find the right processing for OpenCV that will allow you to detect the line
Find a way to transform the output of your OpenCV algorithm into robot movements
Make the robot move given the output of the OpenCV processing
