Camera calibration tools

This repository contains simple OpenCV scripts for performing the camera calibration.

Camera calibration

• ./camera_calibration

Original scripts by Paweł Kolendo (@NieTrawisz) dedicated for recordings in the *.dav format.

Image calibration

• ./image_calibration

Scripts for pre-processing caputered frames

Calculate calibration params

./image_calibration/image_calibration.py -i "path/to/calibration/images/folder" -o "output/folder" --image-format "png" -t 0.2 --grid 9 6

Type -h for help.

Apply calibration to images

./image_calibration/undistortion.py -i "path/to/images/folder" -c "path/to/calibration.npz" -o "output/folder" --image-format "png"

Type -h for help (for instance, there is an option to crop the image with the --crop flag)

Process a dataset

Edit the image_calibration/process_dataset.sh file to your needs.

./image_calibration/process_dataset.sh "path/to/dataset/images/folder"
