EstimateAffine3DTransform

Basic

Module: Calibration

Computes optimal affine transformation between two 3D point sets.

Name Type Range Description
Input value
 inSrcpt Point3DArray List of 3D points in the source coordinate system.
Input value
 inDstpt Point3DArray List of 3D points in the destination coordinate system.
Input value
 inRansacThreshold Real Maximum reprojection error in the RANSAC algorithm to consider a point as an inlier.
Input value
 inConfidence Real 0.0 - 1.0 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.
Output value
 outTransform Matrix Estimated affine transformation matrix.
Output value
 outOutliers IntegerArray Output vector indicating which points are outliers (1-inlier, 0-outlier).
Output value
 outValue Integer

Errors

Error type Description
DomainError EstimateAffine3DTransform failed to find a solution.
DomainError Input arrays must have at least 4 points in EstimateAffine3DTransform.
DomainError Input arrays must have the same number of points in EstimateAffine3DTransform.
