Finds the object pose from 3D-2D point correspondences.

Parameters

object	Single-row matrix of object points.
image	Single-row matrix of image points.
camera_mat	3x3 matrix of intrinsic camera parameters.
dist_coef	Distortion coefficients. See undistortPoints for details.
rvec	Output 3D rotation vector.
tvec	Output 3D translation vector.
use_extrinsic_guess	Flag to indicate that the function must use rvec and tvec as an initial transformation guess. It is not supported for now.
num_iters	Maximum number of RANSAC iterations.
max_dist	Euclidean distance threshold to detect whether point is inlier or not.
min_inlier_count	Flag to indicate that the function must stop if greater or equal number of inliers is achieved. It is not supported for now.
inliers	Output vector of inlier indices.
