Camera Calibration Revisited

This tutorial revisits the calibration of cameras to derive parameters for use in pose estimation (e.g. range, bearing and distance) with robotics applications. The key aspects of this tutorial are:
• Using OpenCV library
• Python and C++ published (by OpenCV) examples
• Chessboard patterns only
The references for the examples are:
• camera_calibrate.cpp, docs.opencv.org/4.x/d4/d94/tu...
• Camera Calibration using OpenCV, learnopencv.com/camera-calibr...
