Description

  The present invention relates to a golf practice system using a ballistic analysis device.

  A golf simulator is known as one of such systems. In the golf simulator, the motion of the shot ball is signaled by a camera or a sensor, and the ball trajectory analysis of the ball is executed based on this signal. Then, the ball trajectory of the ball based on the result of the trajectory analysis is synthesized with the golf course in the virtual space and displayed on a display device such as a screen (for example, Patent Document 1). There is also a function of displaying various shot data based on the result of ballistic analysis.

As one of the ballistic analysis devices, GC2 smart camera system (trademark) of Foresight Sports is known.

  This ballistic analysis device is used by being installed on the same surface as the ball is placed. FIG. 4 shows a state where the surface on which the ball is placed is viewed from above. The ballistic analysis device 51 images the movement of the ball 54 shot within the visual field range 53 of the camera 52 and performs ballistic analysis. Reference numeral 55 denotes a player's stance.

  It is assumed that the position of the ball 54 described with a solid line is a tee-up position by the tee-up device. At this time, it is good to tee up and shot, but when it is desired to shoot without teeing up, the ball 54 is shifted from the tee-up position. However, when the ballistic analysis device 51 is used, the ball 54 must be placed within the field of view range 53 of the camera 52, so the ball 54 must be placed in the vicinity of the tee-up position as shown by the dotted line. . In this case, the player may be concerned about the tee-up position at the time of the shot, and may adversely affect the shot. Further, in this case, the iron shot is repeated within the limited visual field range 53, so that the member on the surface on which the ball within the range is placed is repeatedly struck, and the wear of the member easily proceeds, and the maintenance frequency of the member is increased. There is an inconvenience that goes up.

  An object of the present invention is to make it possible to place a ball with a large shift from a concavo-convex position such as a tee-up position when using a ballistic analysis device of a system that images a ball with a camera. Further, it is an object of the present invention to suppress wear of a member on a surface on which a ball is placed and to reduce the maintenance frequency of the member.

In order to solve this problem, the present invention adopts the following configuration.
In a golf practice system comprising a ballistic analysis device that captures a golf ball at the time of shot with a camera having a certain visual field range and executes ballistic analysis, and outputs information based on the ballistic analysis to an output device,
A camera displacement mechanism that displaces the position of the camera substantially horizontally along the direction of the field of view of the camera, and a control device that drives the camera displacement mechanism to control the camera to the first position and the second position And
A golf practice system in which a golf ball can be placed outside the field-of-view range when the camera is arranged at the first position by arranging the camera at the second position.

  According to the present invention, in the case of using a ballistic analyzer that captures a ball with a camera, the ball can be placed with a large shift from a concavo-convex position such as a tee-up position as compared with the conventional art. Further, since the range in which the ball can be placed is wider than in the past, the iron shot is hit in a wide range, so that wear of the member on which the ball is placed can be suppressed, and the maintenance frequency of the member can be suppressed.

The outline explanatory view by the embodiment of the present invention. Block diagram of the system in the embodiment of FIG. The block diagram of the camera displacement mechanism shown in FIG. Explanatory drawing which shows an example of a ballistic analyzer.

  Embodiments of the present invention will be described below. First, the outline of the present invention will be described with reference to FIG. FIG. 1 shows a state where the play area is viewed from above, as in FIG. The ballistic analysis device 51 provided with the camera 52 is the same as the ballistic analysis device 51 shown in FIG. 4 and has the same visual field range as the camera 52 shown in FIG. In FIG. 1, when the ballistic analysis device 51 is at the position indicated by the dotted line, the visual field range 53 of the camera 52 is the visual field range 53 indicated by the dotted line. This position is the first position, and it is assumed that the field of view is suitable for a tee-up position (position of the ball 54 indicated by a dotted line) by the tee-up device.

  From this position, the ballistic analysis device 51 is displaced substantially horizontally in the direction of the player's standing position, and the ballistic analysis device 51 and the camera 52 are displaced to the position indicated by the solid line in FIG. At this time, the visual field range 53 of the camera 52 is also displaced to the player side to the position of the visual field range 53 shown by a solid line in FIG. This position is defined as a second position. In the visual field range 53 of the camera 52 at the second position, the distance from the tee-up position to the player-side edge of the visual field range 53 is longer than the visual field range 53 of the camera 52 at the first position. Therefore, compared to the state (first position) described with reference to FIG. 4, it is possible to place the ball 54 greatly shifted from the tee-up position to the player side (the ball 54 indicated by a solid line in FIG. 1).

  On the other hand, when the ballistic analysis device 51 is displaced substantially horizontally in the direction away from the player from the first position to be the second position, the ball 54 is teeed as compared to the state described in FIG. 4 (first position). It is possible to place it on the opposite side of the player from the up position. Here, the words “first position” and “second position” are used as words for representing different positions, and do not represent the order of the positions.

  FIG. 2 is a block diagram of this embodiment provided with a mechanism for displacing the camera 52 as described above. A ballistic analysis device 51 including a camera 52 is mounted on the camera displacement mechanism 1. The camera displacement mechanism 1 includes a mechanical mechanism for receiving the drive control signal from the processing device 2 and displacing the ballistic analysis device 51 to the first position or the second position.

  The processing device 2 includes a processor and provides various functions by executing a computer program. The ballistic information processing function generates information to be output to the output device 5 based on the ballistic information received from the ballistic analysis device 51 and outputs the information to the output device 5. For example, the trajectory of the golf ball based on the trajectory information is drawn on the golf course in the virtual space and displayed on the display device 5. Further, the camera displacement control function outputs a drive control signal to the camera displacement mechanism so that the field of view of the camera 52 becomes the first position or the second position in accordance with the input signal from the input device 3. An operation amount to be input to the camera displacement mechanism 1 in order to position the visual field range of the camera 52 at the first position or the second position is stored in the storage device 4 in advance.

  The input device 3 includes an operation element such as a button for the player to select the first position or the second position. In addition, the storage device 4 stores and reads information used by the processing device 2. The output device 5 is a display device such as a projector or a monitor display, a printing device, or the like.

  FIG. 3 is a configuration example of the camera displacement mechanism 1. FIG. 3 shows a state viewed from a direction opposite to the shot direction of FIG. In FIG. 3, a movable plate 12 is disposed opposite to the fixed plate 11, and a slide mechanism 13 that slides the movable plate 12 parallel to the fixed plate 11 is disposed between the fixed plate 11 and the movable plate 12. Equipped. The slide mechanism 13 includes a linear bearing, for example. The fixed plate 11 is fixed to the surface on which the ball 54 is placed. A mounting plate 16 is fixed to the upper portion of the movable plate 12 in parallel with the movable plate 12 via a spacer 17. A ballistic analyzer 51 having a camera 52 is fixed on the mounting plate 16. The movable plate 12 is guided by a guide (not shown) so as to slide along the direction of the visual field of the camera 52.

  On the side opposite to the field of view of the camera 52, the actuator 14 that slides the movable plate 12 along the direction of the field of view of the camera 52 is fixed on the fixed plate 11. The actuator 14 is an air actuator, and slides the movable plate 12 fixed to the tip of the rod 15 as the rod 15 protrudes or is stored in the axial direction. The drive control signal output from the processing device 2 is input to the drive device of the actuator 14, and the ballistic analysis device 51 is moved to the first position shown in FIG. 3A according to the drive control signal, or FIG. Position to the second position shown in (b).

  When the player wants to tee up and take a shot, the player operates the input device 3 to select the first position. In response to this selection operation, the processing device 2 inputs an operation amount for placing the ballistic analysis device 51 at the first position to the camera displacement mechanism 1. The camera displacement mechanism 1 positions the ballistic analysis device 5 at a first position suitable for the tee-up position according to the input operation amount. When the player wants to make a shot without teeing up, the player operates the input device 3 to select the second position. In response to this selection operation, the processing device 2 inputs an operation amount for placing the ballistic analysis device 51 in the second position to the camera displacement mechanism 1. The camera displacement mechanism 1 positions the ballistic analysis device 5 at the second position according to the input operation amount. The player places the ball 54 within the field of view of the camera 52 at the second position. At this time, as shown in FIG. 1, the ball 54 can be placed within the range of the solid line visual field range 53 without being limited to the dotted line visual field range 53, so that the ball 54 is placed as close to the player as possible. Thus, the ball 54 can be placed at a position greatly deviated from the tee-up position, and the inconvenience that the unevenness of the tee-up position becomes a concern during a shot can be improved.

  When the player hits the ball at the first position or the second position, the ballistic analysis device 51 analyzes the ballistic trajectory of the shot ball and inputs ballistic information based on the analysis result to the processing device 2. The processing device 2 generates output information to the output device 5 based on the input ballistic information and outputs it to the output device 5.

  According to the embodiment described above, in the visual field range 53 of the camera 52 at the second position, compared to the visual field range 53 of the camera 52 at the first position, from the tee-up position to the edge of the visual field range 53 on the player side. The distance becomes longer. For this reason, it becomes possible to place the ball 54 largely shifted from the tee-up position to the player side as compared with the first position. Further, since the range in which the ball can be placed is wider than in the past, the iron shot is hit in a wide range, so that wear of the member on which the ball is placed can be suppressed, and the maintenance frequency of the member can be suppressed.

  Here, the present invention is not limited to the above embodiment. For example, in the ballistic analysis device, the camera and the device that performs the ballistic analysis processing may be physically separated. The apparatus may be the processing apparatus 2. The structure of the camera displacement mechanism is not limited. It does not matter whether this system is for indoor use or for outdoor use. It does not matter which of the first position and the second position is closer to the player.
