Tello Camera Calibration

This presentation illustrates the basic steps to calibrate the two cameras on the Tello drone using OpenCV. The Python scripts were adapted from OpenCV examples published by Dr. Satya Mallick et al several years ago. Of course, these scripts were tweaked for user interaction in a custom manner with respect to the retention folders, image acceptance criteria and saving the camera lens properties.
Camera calibration can become an extensive (and intensive) exercise because there are many different patterns, not just checkerboards, that can be used for this purpose. The primary purpose of this tutorial is to illustrate the methodology and hope that others may find the time to perform more rigorous tests.
