Method, device, and non-transitory computer-readable recording medium for estimating information on golf swing

A non-transitory computer-readable recording medium having stored thereon a computer program for causing a mobile device for estimating information on a golf swing to:

• specify at least one analysis target posture from among a plurality of golf swing-related postures;
• light-weight an artificial neural network model using depthwise convolution and pointwise convolution to obtain a light-weighted artificial neural network model, wherein a depth of each kernel in the depthwise convolution is reduced to 1 and each of a width and a height of each kernel in the pointwise convolution is reduced to 1;
• detect at least one of a golf club and at least one joint of a user using the light-weighted artificial neural network model from a video of a golf swing of the user captured by a video capture module, and provide the user with information on an analysis target posture of the user estimated with reference to at least one of a position of the at least one joint and a position of the golf club;
• and
• control the video capture module to capture the video of the golf swing of the user again after a predetermined time elapses from when the information on the analysis target posture is provided.
