FIL.EstimateAffine3DTransform
Computes optimal affine transformation between two 3D point sets.
| Namespace: | FilNet |
|---|---|
| Assembly: | FIL.NET.dll |
Syntax
C++
C#
public static void EstimateAffine3DTransform ( IList<FilNet.Point3D> inSrcpt, IList<FilNet.Point3D> inDstpt, float inRansacThreshold, float inConfidence, FilNet.Matrix outTransform, IList<int> outOutliers, out int outValue )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inSrcpt | System.Collections.Generic.IList<FilNet.Point3D> | List of 3D points in the source coordinate system. | ||
| inDstpt | System.Collections.Generic.IList<FilNet.Point3D> | List of 3D points in the destination coordinate system. | ||
| inRansacThreshold | float | 3.0f | Maximum reprojection error in the RANSAC algorithm to consider a point as an inlier. Default value: 3.0f. | |
| inConfidence | float | <0.0f, 1.0f> | 0.99f | 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. Default value: 0.99f. |
 | outTransform | FilNet.Matrix | Estimated affine transformation matrix. | ||
| outOutliers | System.Collections.Generic.IList<int> | Output vector indicating which points are outliers (1-inlier, 0-outlier). | ||
| outValue | int |
Errors
List of possible exceptions:
| 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. |
