Description
Technical Field
The invention relates to the field of golf simulators, in particular to a golf simulator system.
Background
One of the biggest drawbacks of golf is the requirement for a relatively large amount of space, which makes it expensive in places where land prices are high, and/or the requirement to leave the city to go to a more remote golf course. In recent years, various golf simulators have been developed which can provide, as realistic components, a projected image of a golf course in the eyes of a player and a predicted landing point after the ball is struck. Various sensors are used to monitor the flight path of the ball and/or the trajectory of the club head and use the data obtained to estimate the trajectory of the ball on an unlimited real golf course. With such simulators, it is possible to "experience" golf course goals worldwide in person in a limited small space field that can be accommodated in a central part of a city or anywhere convenient.
However, a characteristic of real golf courses is that different course topographies may result in different lie locations in the actual game. Thus, while the first putt of each hole will generally be played in a substantially flat tee-off area, the ball will then often have to be struck in a lie at a different angle and direction of inclination than the hitter's will. A significant limitation of such golf simulators is that the player is not provided with such a change in the lie, let alone with respect to the estimated lie after the previous shot.
