RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Refines coordinates of corresponding points.

correctMatches(F: Mat, points1: Mat, points2: Mat, newPoints1: Mat, newPoints2: Mat): void;

F

3x3 fundamental matrix.

points1

1xN array containing the first set of points.

points2

1xN array containing the second set of points.

newPoints1

Output destination, filled by the native operation. The optimized points1.

newPoints2

Output destination, filled by the native operation. The optimized points2.

The function implements the Optimal Triangulation Method (see Multiple View Geometry [HartleyZ00] for details). For each given point correspondence points1[i] <-> points2[i], and a fundamental matrix F, it computes the corrected correspondences newPoints1[i] <-> newPoints2[i] that minimize the geometric error d(points1[i], newPoints1[i])^2 + d(points2[i],newPoints2[i])^2 (where d(a,b) is the geometric distance between points a and b ) subject to the epipolar constraint newPoints2^T \cdot F \cdot newPoints1 = 0 .
