EstimateAffine3D(InputArray, InputArray, OutputArray, OutputArray, double, double)

Computes an optimal affine transformation between two 3D point sets.

public static int EstimateAffine3D(InputArray src, InputArray dst, OutputArray outVal, OutputArray inliers, double ransacThreshold = 3, double confidence = 0.99)

Parameters

src InputArray

First input 3D point set.

dst InputArray

Second input 3D point set.

outVal OutputArray

Output 3D affine transformation matrix 3 x 4 .

inliers OutputArray

Output vector indicating which points are inliers.

ransacThreshold double

Maximum reprojection error in the RANSAC algorithm to consider a point as an inlier.

confidence double

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.

Returns

int
