Method, system, and non-transitory computer readable storage medium for supporting virtual golf simulation

A method performed in a system for supporting a virtual golf simulation, the system comprising one or more processors and the method comprising the steps of:

• by the one or more processors, determining, with reference to information on a first reference pattern specified in an image photographed by a first photographing module positioned to photograph a moving subject and information on a second reference pattern specified in an image photographed by a second photographing module positioned to photograph a display area where information associated with the subject is displayed, a positional relationship between coordinates specified in the first photographing module and coordinates specified in the display area;
• and
• by the one or more processors, determining information on a trajectory of the subject in the display area with reference to the positional relationship,
• wherein the display area is distinct from a real-world area where the subject is photographed, and
• wherein in the step of determining the positional relationship, a positional relationship between coordinates specified in the second photographing module and the coordinates specified in the display area is determined on the basis of a correspondence relationship between three-dimensional coordinates of each pattern within the second reference pattern specified with respect to the second photographing module and two-dimensional coordinates of each pattern within the second reference pattern specified with respect to the display area, and the positional relationship between the coordinates specified in the first photographing module and the coordinates specified in the display area is determined with further reference to the positional relationship between the coordinates specified in the second photographing module and the coordinates specified in the display area.
