Abstract: A method for estimating information on a golf swing is provided. The method includes the steps of: specifying at least one analysis target posture from among a plurality of golf swing-related postures; detecting at least one of at least one joint of a user and a golf club using an artificial neural network model from a video of the user's golf swing captured by a video capture module, and providing the user with information on the user's analysis target posture estimated with reference to at least one of a position of the at least one joint and a position of the golf club; and controlling the video capture module to capture the video of the user's golf swing again after a predetermined time elapses from when the information on the analysis target posture is provided.

Abstract: A method for estimating information on a golf swing posture is provided. The method includes the steps of: adjusting a determination criterion for a golf swing of a user on the basis of information associated with the user's golf swing; and estimating information on a golf swing posture of the user on the basis of the adjusted determination criterion, wherein the information associated with the user's golf swing includes at least one of a photographed image of the user's golf swing and information on a swing posture of a comparison target golfer selected by the user.

Abstract: A method for displaying a graphic object on an image is provided. The method includes the steps of: acquiring, with respect to a first graphic object inputted by a user onto a first image of a person's posture, attribute information of the first graphic object that defines the first graphic object; deriving, on the basis of a feature point detected from each of the first image and a second image of a person's posture, a transformation model that defines a transformation relationship between the attribute information of the first graphic object and attribute information of a second graphic object to be displayed on the second image in correspondence to the first graphic object; and displaying, on the basis of the transformation model, the second graphic object at a position on the second image corresponding to a position of the first graphic object on the first image.

Abstract: A method for estimating information on a golf swing is provided. The method includes the steps of: when a photographed image of a user's golf swing is acquired, detecting at least one joint of the user from the photographed image using an artificial neural network model; comparing the user's golf swing and a golf swing of a comparison target with reference to a position of the at least one detected joint; and estimating information on the user's golf swing on the basis of a result of the comparison.

Abstract: A method for estimating information on a golf swing is provided. The method includes the steps of: estimating a three-dimensional position of at least one joint of a user, when two or more two-dimensional photographed images of the user's golf swing taken from different directions are acquired, by deriving probability information on a two-dimensional position of the at least one joint of the user from each of the two or more two-dimensional photographed images using an artificial neural network model, and combining the derived probability information on the two-dimensional position of the at least one joint; and estimating information on the user's golf swing with reference to the estimated three-dimensional position of the at least one joint.

Abstract: A method for estimating information on a golf swing is provided. The method includes the steps of: when a photographed image of a user's golf swing is acquired, detecting at least one joint of the user from the photographed image using an artificial neural network model; and estimating information on the user's golf swing with reference to a position of the at least one detected joint.

Abstract: A method for recommending golf-related contents is provided. The method includes detecting at least one body part of a user from a captured image by using an artificial neural network model, when the captured image related to the golf swing of the user is acquired; estimating at least one problem about the golf swing of the user by referring to the position of the detected at least one body part; and deriving, in reference to information related to the problem associated with the golf-related contents, at least one piece of candidate content associated with the at least one problem from among golf-related contents.
