CvInvokeEstimateAffine3D Method (IInputArray, IInputArray, IOutputArray, IOutputArray, Double, Double)

http://www.emgu.com
Computes an optimal affine transformation between two 3D point sets.

Namespace:  Emgu.CV
Assembly:  Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)
Syntax
public static int EstimateAffine3D(
	IInputArray src,
	IInputArray dst,
	IOutputArray affineEstimate,
	IOutputArray inliers,
	double ransacThreshold = 3,
	double confidence = 0.99
)

Parameters

src
Type: Emgu.CVIInputArray
First input 3D point set.
dst
Type: Emgu.CVIInputArray
Second input 3D point set.
affineEstimate
Type: Emgu.CVIOutputArray
Output 3D affine transformation matrix 3 x 4
inliers
Type: Emgu.CVIOutputArray
Output vector indicating which points are inliers.
ransacThreshold (Optional)
Type: SystemDouble
Maximum reprojection error in the RANSAC algorithm to consider a point as an inlier.
confidence (Optional)
Type: SystemDouble
Confidence level, between 0 and 1, for the estimated transformation. Anything between 0.95 and 0.99 is usually good enough. Values too close to 1 can slow down the estimation significantly. Values lower than 0.8-0.9 can result in an incorrectly estimated transformation.

Return Value

Type: Int32
