  In order to generate a display image such as a three-dimensional CG, polygon data (vertex data) having three-dimensional local coordinate data constituting an object to be displayed or NURBS (Non Uniform Rational B-Spline) is generated in the system memory 32. Data (curved surface and control point data) is stored, and this is arranged in the world coordinate system of the three-dimensional virtual space by the CPU 30 and the geometry processor (not shown) to convert the local coordinates into the world coordinate system.

  Furthermore, the viewpoint coordinates generated as the player operates or plays are set in the world coordinate system, and the object in the field of view as viewed from the viewpoint in the predetermined viewing direction and angle of view is set to the viewpoint coordinates as the origin. The coordinates of the converted object are transmitted to the rendering processor 40.

  The rendering processor 40 first applies interpolation processing such as light source processing or texture data stored in the graphic memory 42 to the object to detail the surface of the object with respect to the coordinates of the object sent. Further, the rendering processor 40 projects an object (polygon) from a three-dimensional solid object onto a two-dimensional plane (screen) and converts it into two-dimensional coordinate data (screen coordinate system) for display on the LCD monitor 15. A two-dimensional image is generated so as to be preferentially displayed from a polygon having a shallow Z coordinate, that is, a polygon close to the viewpoint coordinate, and is output to the LCD monitor 15.

  The detection range of the Doppler sensor is determined by the orientation of the horn-shaped antenna. In FIG. 1 to FIG. 4, the antenna directions of the head Doppler sensor 22 and the ball Doppler sensor 23 are shown so as to be understood.

  In the golf practice apparatus 10 of the present embodiment, two Doppler sensors, a head Doppler sensor 22 for measuring the golf head speed and a ball Doppler sensor 23 for measuring the speed of the golf ball, are provided.

  The head Doppler sensor 22 is provided in the center of the front surface of the main housing 11, and its antenna faces the batting mat 13. As shown in FIG. 3, the detection range of the head Doppler sensor 22 covers almost the entire batting mat 13.

  When the player hits the ball with the golf club, the head Doppler sensor 22 can detect the speed of the head of the golf club and the speed of the hit ball.

  The ball Doppler sensor 23 is provided inside the lower portion of the main housing 11, and its antenna faces the flying direction of the golf ball. As shown in FIG. 3, the detection range of the ball Doppler sensor 23 covers the flying direction of the ball.

  When the player hits the ball with the golf club, the speed of the ball hit by the ball Doppler sensor 23 can be detected. Since the golf club head is outside the detection range of the ball Doppler sensor 23, the head speed is not detected.

  FIG. 4 shows details of the installation positions of the head Doppler sensor 22 and the ball Doppler sensor 23. 4A is a plan view of the main housing 11 of the golf practice device 10 as viewed from above, and FIG. 4B is a front view of the main housing 11 of the golf practice device 10 as viewed from the front.

  As shown in FIG. 4A, the reference line in the ball flying direction from the golf ball set position B is L1, and the reference line perpendicular to the ball flying direction is L2. The distance to the head Doppler sensor 22 with respect to the reference line L1 is A [m], and the distance to the ball Doppler sensor 23 is C [m]. The distance to the head Doppler sensor 22 with respect to the reference line L2 is B [m], and the distance to the ball Doppler sensor 23 is D [m].

  The angle formed by the center line of the horn-shaped antenna of the head Doppler sensor 22 and the line connecting the head Doppler sensor 22 and the ball setting position B is θ1 [degree]. The angle formed by the center line of the horn-shaped antenna of the ball Doppler sensor 23 and the reference line L1 is θ2 [degrees].

  As shown in FIG. 4B, the height of the head Doppler sensor 22 is E [m], and the height of the ball Doppler sensor 23 is F [m]. The center line of the horn-shaped antenna of the head Doppler sensor 22 coincides with the direction of the ball set position B when the main housing 11 of the golf practice apparatus 10 is viewed from the front.

(Ring buffer)
When the golf practice apparatus 10 according to this embodiment is activated, images captured by the front digital video camera 20 provided at the uppermost portion of the main housing 11 are sequentially stored in the front ring buffer 26, and the upper portion of the rear housing 12. Images taken by the rear digital video camera 21 provided in are sequentially stored in the rear ring buffer 27.

  When the image is captured by the front digital video camera 20, new images captured by the front digital video camera 20 are sequentially stored in the front ring buffer 26 while deleting the oldest captured image of the front ring buffer 26. An image captured by the video camera 20 is stored endlessly.

  Similarly, when an image is captured by the rear digital video camera 21, newest captured images by the rear digital video camera 21 are sequentially stored in the rear ring buffer 27 while deleting the oldest captured image from the rear ring buffer 27. Images captured by the rear digital video camera 21 are stored endlessly.

  The front ring buffer 26 and the rear ring buffer 27 have a capacity for storing, for example, a captured image of 4 seconds.

  When the player hits the ball with the golf club, a trigger signal is generated for the front ring buffer 26 and the rear ring buffer 27 at a predetermined time, and the storage of a new captured image in each ring buffer is stopped based on the trigger signal, A video image of the player's optimal batting play is extracted and played back for player practice.

  FIG. 5 is a diagram showing a state when the player hits the ball with the golf club. FIG. 5A is a front view of the main housing 11 of the golf practice apparatus 10. FIG. 5B is a view of the main housing 11 of the golf practice apparatus 10 as viewed from above and a captured image of the ring buffers 26 and 27.

  A state in which the ball B is hit by the head H of the golf club swung by the player and flies forward is shown.

  The speed of the golf ball B is detected by the ball Doppler sensor 23, but the ball speed is not determined immediately after being hit. Based on the detection signal from the ball Doppler sensor 23, the sensor control unit 24 determines that the ball has been hit normally by the golf club when there is a detection signal when the swing is detected from the head Doppler sensor 22. And determine the ball speed measurement.

  In the present embodiment, when a measurement value of the ball speed is determined, a trigger signal is generated for the front ring buffer 26 and the rear ring buffer 27, and the captured images for a predetermined time before and after the determination time are used as a reference. Are extracted as video images for reproduction. For example, a captured image of 4 seconds from 2.5 seconds before the ball speed determination to 1.5 seconds after the ball speed determination is extracted as a video image for reproduction.

  As described above, according to this embodiment, since the time when the ball speed is determined is used as a trigger, it is possible to extract a video image only when the ball actually flies. The video image when the player fails to hit is not erroneously extracted. If the time when the golf club head speed is detected is used as a trigger, a video image when the player fails to hit is also extracted.

  Further, according to the present embodiment, since the time of determining the ball speed is used as a trigger, it is possible to extract video images of an appropriate period desired by the player in the ring buffers 26 and 27.
