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."
