It is an image of a golf ball B or lawn S taken by means 24.

  The liquid crystal display 13 receives various display control signals from the control means 21 and performs various displays. As is well known, this is a display using a dot matrix in which a large number of sub-pixels are arranged in a grid pattern. .

  The transmission / reception means 25 enables bidirectional communication between the measurement unit 3 and an external device (not shown) via a wireless or wired communication means 32. As a result, a dedicated application program for operating the control means 21 as the golf practice tool of the present embodiment is received by the transmission / reception means 25 from the center server as an external device via the communication means 32 such as the Internet as needed and stored. The means 26 can be stored and saved.

  The storage means 26 is configured by using various storage devices such as a magnetic hard disk device and a semiconductor storage device. Here, the swing means data relating to the swing orbit of the putter head 7 obtained based on the detection output from the sensor means 23, and golf In addition to the initial speed determination data relating to the initial speed of the ball B, lawn data relating to the strength and inclination of the lawn G obtained based on the image data from the photographing means 24, and the rotational direction relating to the rotational direction of the golf ball B A data storage area for storing data and a program storage area for storing a program related to the dedicated application are provided. Based on instructions from the control means 21, various data and programs stored in the storage means 26 can be read and written.

  Next, the software configuration of the program that operates the control means 21 will be described. The control unit 21 has a configuration that functions as a sensor output analysis unit 41, an image processing analysis unit 42, and a locus calculation control unit 43 by reading a program recorded in the storage unit 26.

  The sensor output analysis unit 41 takes in the detection output when the putter main body 2 is swung from the sensor means 23, specifies the swing trajectory in which the putter head 7 was swung, and uses this as the swing trajectory data. Is stored in the data storage area of the storage means 26. Further, the sensor output analysis unit 41 takes in the vibration of the putter head 7 generated at the moment when the golf ball B hits the face surface 6 as a detection output from the sensor means 23 and determines the initial velocity of the golf ball B therefrom. The initial speed determination data is stored in the data storage area of the storage means 26.

  The image processing analysis unit 42 recognizes and analyzes the portion of the image data photographed by the photographing means 24 to become the lawn G, thereby determining the direction and strength of the lawn in the lawn G and the golf ball B The strength of the slope of the lawn G serving as the ground contact surface is acquired as lawn data relating to the degree of lawn and the degree of slope, and is stored in the data storage area of the storage means 26. In addition, the image processing analysis unit 42 recognizes a portion that becomes the golf ball B in the moving image data photographed by the photographing unit 24 and analyzes the image to thereby obtain rotational direction data specifying the rotational direction of the golf ball B. The data is stored in the data storage area of the storage means 26.

First, in use, the weight member attached to the receiving portion 11 of the putter head 7 is removed, and instead the measuring unit 3 is attached to the receiving portion 11, and the dedicated unit stored in the storage means 26 by operating the touch panel 14. The application is activated (step S1). If the light emitter 1 is electrically connected to the measurement unit 3, the line-shaped laser light L is emitted from the face surface 6 of the putter head 7 through the window hole 8 with the activation of the application in the measurement unit 3. . When the light emitter 1 operates alone, the laser light L can be similarly emitted from the face surface 6 of the putter head 7 by a switch operation provided in the light emitter 1.

  Next, relying on the laser light L, while confirming the direction of the face surface 6 on which the golf ball B is hit, the camera lens 12 is directed in a direction to swing the putter head 7 and the putter head 7 is placed on the lawn G. Put it on the surface. At this time, when the image processing analysis unit 42 recognizes a portion to be the lawn G in the image data photographed by the photographing unit 24 (step S2), the image processing analysis is performed to obtain lawn data regarding the degree of lawn and inclination. (Step S3) and stored in the storage means 26.

  Thereafter, when the sensor output analysis unit 41 recognizes that the swing of the putter head 7 has exceeded the preset threshold and the swing has been performed in accordance with the user's putting operation based on the detection output captured from the sensor means 23 ( In step S4), the data of the swing trajectory indicating the trajectory in which the putter head 7 was swung is acquired (step S5), and this is stored in the storage means 26.

  Then, when the face surface 6 comes into contact with the golf ball B placed on the lawn G by the swing of the putter head 7, the vibration associated with the impact on the putter head 7 is detected as the detection output from the sensor means 23 and the sensor output analysis Part 41 is taken in. The sensor output analysis unit 41 recognizes the vibration at this time (step S6), and determines and acquires the initial velocity immediately after the golf ball B hits the face surface 6 (step S7). It is stored and saved in the storage means 26 as initial determination data.

  Further, when the image processing analysis unit 42 recognizes the rotation direction immediately after the golf ball B hits the face surface 6 in the moving image data photographed by the photographing means 24 (step S8), the rotation specifying the rotation direction is performed. Direction data is acquired (step S9) and stored in the storage means 26.

  In the procedure of step S9, the trajectory calculation control unit 43 continues to read the lawn data, the swing trajectory data, the initial determination data, and the rotation direction data stored so far in the storage unit 26, and the lawn G is read from each of these data. A predicted trajectory of the golf ball B rolling up is calculated, and the calculation result is displayed on the liquid crystal display 13. As a result, the user accurately determines not only the direction of the face surface 6 using the laser beam L but also the course of the golf ball G applied to the face surface 6 for each putting operation of hitting the golf ball G with the golf practice tool. It becomes possible to grasp. Further, in the present embodiment, the predicted trajectory of the golf ball B can be calculated with high accuracy in consideration of the lawn data, the swing trajectory data, the initial determination data, and the rotation direction data, and the user's putting technology is improved. Contributes significantly.

  Note that the series of procedures shown in FIG. 4 is merely an example, and the order may be appropriately changed. For example, the procedure of steps S2 and S3 can be omitted by causing the golf ball G and the lawn G to be recognized in the procedure of step S8 and acquiring the rotation direction data and the grass data in the next step S9. Further, in the procedure of steps S2, S4, S6, and S8, when recognition is not possible even after a predetermined time has elapsed, an error may be displayed on the liquid crystal display 13 and the procedure may be forcibly returned to the procedure of step S1. .

  The control means 21 has a function as a display control means for switching the display form of the liquid crystal display 13 in response to an operation signal from the touch panel 14. FIG. 5A shows another display mode in which the lawn data obtained by the image processing analysis unit 42 is displayed on the liquid crystal display 13. Here, with respect to the lawn G photographed by the photographing means 24, the lawn display unit 51 showing the direction and strength of the lawn with white arrows, and the lawn slope display unit 52 showing the inclination angle of the lawn G with numbers. Are displayed at the same time. In particular, the turf eye display unit 51 matches the projection direction of the arrow according to the direction of the turf and increases the number of arrows as the turf becomes stronger, so that the situation of the turf can be confirmed at a glance. ing. Further, by displaying the lawn inclination display unit 52 together with the lawn display unit 51, the user can comprehensively understand the situation of the lawn G before the putting operation. The screen of FIG. 5A may be automatically displayed on the liquid crystal display 13 when the lawn data is acquired in step S3 of FIG.

  Further, in the present embodiment, in FIG. 5A, the touch panel on the screen switching display unit 53 in which “PUTT PREVIEW” is displayed from the screen on which the above-mentioned lawn eye display unit 51 and lawn inclination display unit 52 are displayed. 14 is configured to be switched to another screen displaying a ball rolling direction display unit 54 as shown in FIG. Here, the ball rolling direction display section 54 indicates the predicted rolling direction of the golf ball B at the time of putting with an arrow and, for example, a character “Break To Left”. Can understand at a glance which direction the golf ball B should be rolled before the putting operation.

  The screen before the putting operation shown in FIGS. 5A and 5B is automatically switched to the screen after the putting operation shown in FIGS. 1 and 2 when step S9 shown in FIG. 4 is completed. It is good.
