Camera Calibration

This repository provides tools for calibrating a camera using OpenCV. To perform camera calibration, you will need a calibration board featuring white and black squares, similar to a chessboard.

Obtaining Calibration Points from the Calibration Board

To capture calibration points from the calibration board, use the following command:

python main.py capture -x number_of_squares_along_x -y number_of_squares_along_y --camera camera_id --dt time_delay_after_a_successful_detection

Place the calibration board in front of your camera, and this command will automatically save the necessary data.

Checking Saved Data

To check the saved calibration data, run the following command:

python main.py info

This command will display the number of images available for calibration and the shape of these images. To ensure a successful calibration, all images must have the same shape.

Processing Calibration Parameters

To process the captured data and obtain the camera parameters, execute the following command:

python main.py process

The results will be saved in a file named solution.yml.

Running a Simple Demo

To visualize the camera calibration results, a simple demo is available. This demo will draw the X, Y, and Z axes on the calibration board. Execute the following command:

python main.py demo

Deleting Data

If you need to delete the previously captured calibration data, whether due to its quality or to calibrate another camera, use the following command:

python main.py supp
