+    :param projPoints1: 2xN array of feature points in the first image.
+
+    :param projPoints2: 2xN array of corresponding points in the second image.
+
+    :param points4D: 4xN array of reconstructed points in homogeneous coordinates.
+
+The function reconstructs 3-dimensional points (in homogeneous coordinates) by using their observations with a stereo camera. Projections matrices can be obtained from :ocv:func:`stereoRectify`.
