Abstract
The invention relates to a method for the analysis of movement of a piece of sports equipment of a type of ball sport, in particular a racket, preferably a golf club, or a ball, preferably a golf ball, wherein a first virtual trajectory model is reproduced in a display device in a way that said first virtual trajectory model is displayed as a first line on the display device in superimposition with at least one, in particular in reality, visible section of the environment, particularly when a field of view is directed on the at least one section of the environment which is visible in reality.
Claims9
A system for analyzing the movement of at least one piece of sports equipment for a type of ball sport, comprising:
- a projector arranged to generate projections on at least one playing field;
- a data interface or scanning apparatus arranged to detect in a reference system a position of the projector, a defined start position and a target position for a ball of the type of ball sport, and at least one environmental parameter which comprises a topographical parameter that characterizes the topography and which at least partially characterizes an environment within an area between the start position and the target position;
- a processing unit arranged to utilize the reference system in calculating an ideal trajectory of the at least one piece of sports equipment based on the start position of the ball, the target position of the ball, and the at least one environmental parameter, and to generate a first virtual trajectory model, adapted to the topography based on the topographical parameter, of the at least one piece of sports equipment in at least one section of the environment on the basis of the calculated ideal trajectory of the at least one piece of sports equipment,
- wherein the processing unit is configured to operate the projector to project the start position of the ball and the first virtual trajectory model onto the playing field as a first line, and
- wherein the first line connects the start position and the target position and is adapted to a topography that is characterized by the topographical parameter.
A system for analyzing the movement of at least one piece of sports equipment for a type of ball sport, comprising:
- a projector arranged to generate projections onto at least one environment;
- a data interface or scanning apparatus arranged to detect in a reference system a position and/or orientation of the projector, a defined start position and a target position for a ball of the type of ball sport, and at least one environmental parameter that comprises a topographical parameter, which characterizes the topography, and that at least partially characterizes an environment within an area between the start position and the target position;
- and
- a processing unit arranged to utilize the reference system in calculating an ideal trajectory of the at least one piece of sports equipment based on the start position of the ball, the target position of the ball, and the at least one environmental parameter in order to calculate a field of view of the projector in the reference system on the basis of the detected position and/or the orientation of the projector, and to generate a first virtual trajectory model, adapted to the topography based on the topographical parameter, of the at least one piece of sports equipment in at least one section of the environment on the basis of the calculated ideal trajectory of the at least one piece of sports equipment,
- wherein the processing unit is configured to operate the projector to project the start position of the ball and the first virtual trajectory model onto the environment as a first line, and
- wherein the first line begins at the start position and intersects the target position, the first line being adapted to a topography that is characterized by the topographical parameter.
