sfmfunctionOpenCV 5.0.0
import { sfm_computeOrientation } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSx1, x2, R, t
FUNCTIONsfm_computeOrientation
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Computes Absolute or Exterior Orientation (Pose Estimation) between 2 sets of 3D point.

sfm_computeOrientation(x1: MatVector, x2: MatVector, R: Mat, t: Mat, s: number): void;
x1

Input first 3xN or 2xN array of points.

x2

Input second 3xN or 2xN array of points.

R

Output destination, filled by the native operation. Output 3x3 computed rotation matrix.

t

Output destination, filled by the native operation. Output 3x1 computed translation vector.

s

Output computed scale factor.

Find the best transformation such that xp=projection*(sRx+t) (same as Pose Estimation, ePNP). The routines below are only for the orthographic case for now.
