Sharding your database
Link: Sharding your database: "I’m increasingly encountering users on Heroku that are encountering the need to shard their data. For most users this is something you delay as long as possible as you can generally go for sometime before you have to worry about it. Additionally scaling up your database is often a reasonable approach early on and something I encourage as a starting point as scaling up is easy to do with regards to databases. However, for the 1% of users that do need to shard when the time comes many are left wondering where to start, hence the following guide."
The Ultimate Guide to Real-Time Lane Detection Using OpenCV – Automatic Addison
Link: The Ultimate Guide to Real-Time Lane Detection Using OpenCV – Automatic Addison: "In this tutorial, we will go through the entire process, step by step, of how to detect lanes on a road in real time using the OpenCV computer vision library and Python. By the end of this tutorial, you will know how to build (from scratch) an application that can automatically detect lanes in a video stream from a front-facing camera mounted on a car. You’ll be able to generate this video below."

Calibrating a Monocular Camera with ROS - Robotics with ROS
Link: Calibrating a Monocular Camera with ROS - Robotics with ROS: "ROS use OpenCV for camera calibration but the format that it stores the data is different than OpenCV. Also, you need to know where to place the camera calibration files so ROS can find it and publish it. 1.First, you need to install usb cam package from ROS and uvcdynctrl to disable autofocus: sudo apt-get install ros-kinetic-usb-cam uvcdynctrl 2.Open … Calibrating a Monocular Camera with ROS Read More »"

Fiducial-Based Localization
Link: Fiducial-Based Localization: "Tutorials for MagniThis document discusses running our fiducial based navigation software on a Ubiquity Robotics robot base, using the supported Raspberry Pi camera. It also assumes that you have a workstation with ROS installed, which is connected to a network in common with the robot. You will need a printer, too."

OpenCV: Detection of ArUco Markers
Link: OpenCV: Detection of ArUco Markers: "Pose estimation is of great importance in many computer vision applications: robot navigation, augmented reality, and many more. This process is based on finding correspondences between points in the real environment and their 2d image projection. This is usually a difficult step, and thus it is common to use synthetic or fiducial markers to make it easier."
