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

Parameters
objectSingle-row matrix of object points.
imageSingle-row matrix of image points.
camera_mat3x3 matrix of intrinsic camera parameters.
dist_coefDistortion coefficients. See undistortPoints for details.
rvecOutput 3D rotation vector.
tvecOutput 3D translation vector.
use_extrinsic_guessFlag to indicate that the function must use rvec and tvec as an initial transformation guess. It is not supported for now.
num_itersMaximum number of RANSAC iterations.
max_distEuclidean distance threshold to detect whether point is inlier or not.
min_inlier_countFlag to indicate that the function must stop if greater or equal number of inliers is achieved. It is not supported for now.
inliersOutput vector of inlier indices.
