In addition, in the case of using the sensor as described above, the golf ball must be placed on the sensor in order to start the measurement. In the case of LD or LED array, the measurement error is large when the lattice spacing is wide, and the golf ball firing angle is LD.

The club head 2 includes a section from a first event frame to a first end frame which has been arbitrarily set by the user, and after the first start frame of the image corresponding to the second interest section. And a section from the second start frame when entering the region of interest 11 to the second end frame immediately before the golf ball 1 leaves the second region of interest 11.

The first surveillance zone 20 or the second surveillance zone 21 may play golf in the first region of interest 10 or the second region of interest 11, as shown in FIGS. 3 (a) and 3 (b). It is an adjacent predetermined area where the ball 1 is located. It is set one by one in the direction in which the club head 2 enters the golf ball 1 by the user's swing and in the direction in which the ball 1 advances after hitting the golf ball 1. It is preferable to be.

The first surveillance zone 20 or the second surveillance zone 21 may be used to measure the brightness values for the surveillance zones 20 and 21 and automatically set the monochrome level value, gain, and color value during image processing. have. That is, when the brightness value for the first surveillance zone 20 or the second surveillance zone 21 is different from the preset brightness value for the first ROI 10 or the second ROI 11, By adjusting the brightness values for the entire region of interest, it is possible to clearly take the contours of the golf ball 1 and the club head 2 in the image processing.

However, in this case, the brightness value of the first surveillance zone 20 or the second surveillance zone 21 is such that the first region of interest 10 or the second region of interest is not so software-processed through image processing. In the case where there is a large difference from the preset brightness value with respect to (11), the golf simulation system using the ultra-fast machine vision camera of the present invention uses an illumination means 500 that provides light to secure exposure to the image sensor of the camera. It may further include.

The first display means 300 displays an image acquired by the first camera 100 or the second camera 200 or the golf ball 1 or the club head 2 through image processing or pattern recognition by the controller. The movement trajectory may be displayed or the movement trajectory may be displayed together with the image acquired by the cameras 100 and 200.

One or more of the movement trajectories of the golf ball 1 or the club head 2 acquired through the 200 can be reproduced, thereby enabling a clear and easy consideration of the user's swing posture, and correcting the swing posture. It can increase the learning efficiency.

At this time, in reproducing the movement trajectory for the golf ball 1 or the club head 2, the user's selection shows the swing posture of the user and the movement trajectory for the golf ball 1 or the club head 2 is displayed. It is preferable to play the swing posture and the movement trajectory together in order, or to play the swing posture or the movement trajectory within a certain section sequentially or simultaneously with respect to the moment of impact, so as to reproduce selectively according to the user's ability. .

Depending on the direction, it is possible to obtain an accurate turn rate. For example, the firing angle of the golf ball 1 was measured using a frame of +1 and 0, that is, a still image, but the movement of the golf ball 1 in the frame +2 and +1 frame thereafter. Angle(

As shown in FIG. 6, in the golf simulation method, at least one camera acquires an image including an image in which the club head 2 is impacted on the golf ball 1 by a user's swing (S100). The step (S200) of extracting the outline of the club head 2 or the golf ball 1 for the impacted image through an image processing or pattern recognition method (not shown) and the controller is performed by extracting the club head (from the extracted outline image). 2) or calculating the physical characteristics of the golf ball 1 (S300), wherein the storage means (not shown) stores the impacted image (S260), the first display means 300 is a golf ball (1) or displaying the movement trajectory of the club head (S400) or the second display means 400 displays the flight scene of the golf ball (1) based on the physical characteristics of the golf ball (1) It may further comprise the step (S500).

Acquiring an image in which the club head 2 is impacted on the golf ball 1 (S100), as in the golf simulation system using the super high speed machine vision camera, is exposed to the fast shutter speed in the high speed machine vision camera. In order to secure the control unit may perform an image processing or turn on the lighting through the lighting means (500).

At this time, when the brightness value for the first surveillance zone 20 of the image of the golf ball 1 obtained from the first camera 100 is different from the brightness value for the entire image of the first region of interest 10, The controller may modify the brightness value of the entire image of the first region of interest 10 or turn on the lighting through the lighting means 500, and among the images of the golf ball 1 acquired from the second camera 200. If the brightness value for the second surveillance zone 21 is different from the brightness value for the entire image of the second region of interest 11, the controller corrects or illuminates the brightness value for the entire image of the second region of interest 11. The means 500 may be adapted to turn on the illumination.

The control unit extracts the outline of the club head 2 or the golf ball 1 for the image that the club head 2 impacts the golf ball 1 through image processing or pattern recognition (S200). Storing the acquired image in a temporary storage means (not shown) (S210), and searching for whether the controller includes an image that is impacted on the image stored in the temporary storage means (S220). In the case of deleting the image stored in the temporary storage means, periodically re-storing the image after a randomly set time (S230) and when finding the impacted image, determining the image stored in the temporary storage means as the interest interval (S240). In addition, the control unit may set the first start frame, the first event frame, the first end frame, the second start frame, the second event frame, and the second end frame. A step (S250) may further include.

That is, when the golf ball 1 is deviated from the region of interest 10 and 11 among the images continuously acquired by the cameras 100 and 200 according to a predetermined period set arbitrarily, the golf ball 1 is for a predetermined time. In case of stopping and moving, the event is regarded as occurring and the part including the image where the event occurs, that is, the image of the corresponding section of interest for a predetermined time is stored in the temporary storage means. Thereafter, the image of the section from the start frame to the end frame among the images stored in the temporary storage means is stored in the storage means, from which the physical properties of the golf ball 1 or the club head 2 are calculated and displayed. Through (300, 400).

Hereinafter, the step (S250) of setting the start frame, the event frame and the end frame of the interval of interest will be described in detail.

7 is a flowchart illustrating a method of setting various frames within a region of interest according to an embodiment of the present invention.

As shown in FIG. 7, in the step S250 of setting the various frames included in the first interest section or the second interest section, the control unit sequentially sets the golf ball 1 of the second interest section frames in the second direction. In step S251, the frame immediately before leaving the region of interest 11 is set as the second end frame, and the frame at the moment when the club head 2 impacts the golf ball 1 among the frames of the second region of interest is second. Setting as an event frame (S252), setting a frame recorded in the same time zone among the first interest interval frames as the first event frame based on the absolute time of the controller for the second event frame (S253) 2, when the clubhead 2 of the frames of interest frames enters the second region of interest 11, the frame is set as a second start frame (S254). The frame stops and starts moving backwards Setting a first start frame recorded in the same time zone among first frames of interest intervals based on the time of the controller (S255); and ending the frame recorded after a randomly set time from the first event frame. A step of setting the frame (S256) is included.

The start frame, the event frame and the end frame are set by the above method, but in particular, the event frame is set based on the time included in the control unit itself, and thus, the golf ball 1 or the club head 2. It can be an absolute criterion as a criterion for calculating the physical properties of the and thus allows precise calculations.

Subsequently, in operation S260, the storage means stores the image in which the storage means is stored. As described above, the image stored in the storage means may include the first interest frame to the first end frame or the second interest in the first interest section. The second frame may include a second start frame to a second end frame.

That is, the section stored by the storage means is the user in the first event frame at the moment when the club head 2 is impacted on the golf ball 1 from the first start frame where the club head 2 stops and starts moving backwards. The first end frame, which is arbitrarily set by the second end frame, and the golf ball 1 becomes the second region of interest from the second starting frame when the club head 2 enters the second region of interest 11. Up to the second end frame, which is before exiting. The physical characteristics of the golf ball 1 or the club head 2 are then calculated on the basis of the image stored in the storage means, and then displayed on the first display means 300 or the second display means 400.

The step S400 of displaying the movement trajectory of the golf ball 1 or the club head 2 by the first display means 300 reproduces only an image acquired through the first camera 100 or the second camera 200. Display or reproduce only the movement trajectories of the golf ball 1 or the club head 2, or display the golf ball 1 or the club head in an image acquired through the first camera 100 or the second camera 200. The movement trajectory of 2) can be reproduced and displayed together, and the golf scene 1 can be displayed on the second display means 400 based on the physical characteristics of the golf ball 1. Simulation becomes possible.
