Detailed Description

A filter for undistorting images.

This filter enables the correction of lens-distorted images. The corresponding correction table is generated for a calibration configuration and a specified image size, which is then applied to distorted images of the same size.

To correct individual pixel positions, see UndistPointFilter.

create()

cvb.UndistImageFilter create	(	str	calibration_data,
		cvb.Size2D	image_size,
		bool	crop,
		Optional[int]	interpolation_mode )

Creates an image undistortion filter for a given calibration configuration.

This filter calculates undistorted 2D images from distorted 2D images for the calibration configuration given at filter creation.

Parameters

calibration_data : str Calibration configuration in JSON format.

image_size : cvb.Size2D The size of the images to undistort.

crop : bool Flag, whether the output image contains only valid pixels.

interpolation_mode : Optional[int] Interpolation mode used for the undistorted image (see cvb.UndistInterpolationMode).

Returns

cvb.UndistImageFilter The generated filter.

undistort()

cvb.Image undistort	(		self,
		cvb.Image	image )

Undistort a distorted image.

Returns an undistorted image.

Parameters

image : cvb.Image The distorted image.

Returns

cvb.Image The undistorted image.
