1. 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.

2. The system for analyzing movement according to claim 1 further comprising:

a user interface arranged to detect a start position of the ball of the type of ball sport in a reference system by means of input by a user.

3. The system according to claim 1 , wherein the projector further comprises at least one accelerometer and one gyrosensor in order to measure movement in six degrees of freedom and wherein the processing unit is further arranged to determine, by means of coupling, an actual position and/or an actual orientation of the display device based on a position and/or an orientation of the display device determined by the tracking module.

4. The system of claim 1 further including a tracking module, arranged to detect a start position of a ball of the type of ball sport and a defined target position for the ball in a reference system and to detect a position and/or an orientation of the display device in the reference system.

5. The system according to claim 1 , further including a tracking module that is arranged to determine an actual position of the piece of sports equipment and/or wherein the system further comprises a radiolocation device in order to determine the actual position and/or an actual trajectory of the piece of sports equipment, and wherein the display device is further arranged to display the actual position and/or the actual trajectory of the piece of sports equipment.

6. The system according to claim 5 , wherein the system is additionally configured to display a deviation between the actual position and/or trajectory of the piece of sports equipment and the ideal position and/or trajectory of the piece of sports equipment.

7. The system of claim 1 wherein the projector projects the first virtual trajectory model onto the playing field in real time.

8. The system of claim 1 , wherein the data interface or scanning apparatus is additionally arranged to detect a defined standing position of a player and the projector projects the defined standing position onto the playing field.

9. 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.
