+
+    Finds the object pose from the 3D-2D point correspondences.
+    
+    :param object: Single-row matrix of object points.
+    
+    :param image: Single-row matrix of image points.
+    
+    :param camera_mat: 3x3 matrix of intrinsic camera parameters.
+    
+    :param dist_coef: Distortion coefficients. See :c:func:`undistortPoints` for details.
+    
+    :param rvec: Output 3D rotation vector.
+    
+    :param tvec: Output 3D translation vector.
+    
+    :param use_extrinsic_guess: Indicates the function must use ``rvec`` and ``tvec`` as initial transformation guess. It isn't supported for now.
+    
+    :param num_iters: Maximum number of RANSAC iterations.
+    
+    :param max_dist: Euclidean distance threshold to detect whether point is inlier or not.
+    
+    :param min_inlier_count: Indicates the function must stop if greater or equal number of inliers is achieved. It isn't supported for now.
+    
+    :param inliers: Output vector of inlier indices.
