CreateRectificationMap_Basic

Computes a spatial map for removing lens and perspective distortion directly from an image containing circles calibration pattern. Internally uses a pinhole camera model with polynomial lens distortion.

Applications: Quick and easy one-step calibration for basic removal of lens and perspective distortions.

Syntax

void fil::CreateRectificationMap_Basic
(
	const fil::Image& inImage,
	float inCircleRadius,
	float inCircleDetectionThreshold,
	ftl::Array<fil::AnnotatedPoint2D>& outImageGrid,
	fil::RectificationMap& outRectificationMap
)

Parameters

	Name	Type	Range	Default	Description
	inImage	const Image&			Input image
	inCircleRadius	float	1.0 -		Circle radius measured in input image pixels.
	inCircleDetectionThreshold	float	0.0 -	20.0f	Detection threshold (relative to local image patch).
	outImageGrid	Array<AnnotatedPoint2D>&			Detected grid, upon which the calibration will be based.
	outRectificationMap	RectificationMap&
