machinevisiontoolbox.Image.undistort

Image.undistort(K, dist)

Undistort image

Parameters:

• K (ndarray(3,3)) – camera intrinsics

• dist (array_like(5)) – lens distortion parameters

Returns:

undistorted image

Return type:

Image

Remove lens distortion from image.

The distortion coefficients are \((k_1, k_2, p_1, p_2, k_3)\) where \(k_i\) are radial distortion coefficients and \(p_i\) are tangential distortion coefficients.

Example:

>>> from machinevisiontoolbox import Image, ImageCollection
>>> import numpy as np
>>> images = ImageCollection("calibration/*.jpg")
>>> K = np.array([[ 534.1, 0, 341.5], [ 0, 534.1, 232.9], [ 0, 0, 1]])
>>> distortion = np.array([ -0.293, 0.1077, 0.00131, -3.109e-05, 0.04348])
>>> out = images[12].undistort(K, distortion)
>>> out.disp()
