A method of spatialTransformField.

the field of the displacements of the point pairs, at the points of frame A

Syntax

T = spatialTransformField.fit(posA, posB)

The displacements as measured.

Description

There is nothing to fit: the field interpolates its samples exactly. The weights only drop the points whose weight is not a number, as the points with a missing position are dropped, so the same call works on the output of a failed correlation; a weight zero is kept, as MATLAB keeps it.

Input

posA vector3d, the positions in frame A
posB vector3d, the same points in frame B

Keywords

keyword default description
weights None one weight per point

Output

T spatialTransformField
