2016-08-02 10:33:56 -0600	commented answer	Measuring Planar Objects with a Calibrated Camera Thanks, i'm still struggling to get the correct equation. My python to go from object points to image points looks like this: `object_points = np.array([[0, 0, .4], [.3, .2, .4]])` `image_points, jacobian = cv2.projectPoints(object_points, rvec, tvec, camera_matrix, dist_coefs) cv2.line(img, tuple(image_points[0].astype(int).ravel()), tuple(image_points[1].astype(int).ravel()),(0, 255, 0), 1) image_points = np.array([[100, 100], [200, 200]])` `object_points_on_plane = ????` but i'm unsure how to go back to object points on a plane from image points.

2016-07-08 23:00:58 -0600	asked a question	Measuring Planar Objects with a Calibrated Camera I would like to measure some coins placed on top of a calibration plate, as per this matlab example http://mathworks.com/help/vision/exam... . Does OpenCV have an equivalent to the pointsToWorld function that lets you pass in pixel X,Y's and get world X,Y's on a plane?
