Camera Calibration Module

This repo consists of two parts to help camera calibration using OpenCV-python.

1. Get Callibration matrix

The number of inner corner is required. The checker board which is provided in 'demo/pattern_chessboard.png' has 9 and 6 corners in width and height respectively. Multiple checker board images with different angle could improve the accuracy.

2. Undistort images using information of calibration.

By using the calibration matrix and distortion factors, images can be undistorted.
