triangulatePoints()

void cv::sfm::triangulatePoints	(	InputArrayOfArrays	points2d,
		InputArrayOfArrays	projection_matrices,
		OutputArray	points3d
	)

#include <opencv2/sfm/triangulation.hpp>

Reconstructs bunch of points by triangulation.

Parameters

points2d	Input vector of vectors of 2d points (the inner vector is per image). Has to be 2 X N.
projection_matrices	Input vector with 3x4 projections matrices of each image.
points3d	Output array with computed 3d points. Is 3 x N.

Triangulates the 3d position of 2d correspondences between several images. Reference: Internally it uses DLT method [HartleyZ00] 12.2 pag.312
