Description
Technical field
The utility model relates to a kind of sensing device, relates in particular to a kind of sensor device of indoor golf simulator.
Background technology
In the indoor golf motion, measuring system just sensor is the gordian technique of indoor golf, and its technical feature directly affects the technical feature of indoor golf simulation system.The device that at present most data transducer is adopted is a photodiode, infrared receiving tube and ccd video camera.The well-known skyborne motion of ball is except that the influence of wind-engaging, two initial vectors that depend on ball fully, be the linear velocity initial vector of ball and the rotation initial vector of ball, for the linear velocity initial vector, all complete the measuring of energy of the sensor of present most of indoor golf, some sensor then can only be measured the component of initial vector on ground level, lacks the height component.For the initial rotational speed vector of ball, still can not completely measure at present, but some sensor can be measured the initial rotational speed vector of the left-handed or dextrorotation of ball, on revolve or the rotational speed of chop still difficulty measure.
At present common indoor golf sensor is surveyed ball sensor and door case type sensor for fixed point measuring staff sensor, fixed point, below the defective that exists of these several sensors of labor:
Fig. 1 measuring staff sensor synoptic diagram of fixing a point, as shown in Figure 1: the main element of this sensor is photodiode or infrared receiving tube, on the center sensor line, be provided with ball seat (Tee) 5, point-source light or infrared transmitting tube are equipped with in the overhead about 300 centimeters places of ball seat, there is row's photodiode 1 to be used for determining whether ball is hit away before the ball seat, 2,3 and 4 three combs are arranged behind the ball seat, that row 2 has 14 pipes near ball seat, that row 4 has 26 pipes away from ball seat, this two comb is used for the velocity vector that square stance is measured club, in fact can only measure X to and Z to speed component.Middle that row 3 has only two pipes, be used to measure club before bumping ball moment club the projection of normal vector on the XZ plane and the angle β of X-axis of striking surface.Add the bar number of player input or the bar number (having equaled to import the normal vector of club striking surface and the angle α of ground level) of computer caddiecaddy prompting, but just indirect calculation go out ball the y of linear velocity to component, by club Z to speed component, α and β can extrapolate the initial rotational speed vector of the left-handed or dextrorotation of ball.
The advantage of fixed point measuring staff sensor is small and exquisite, be easy for installation and maintenance, can measure the initial rotational speed vector of left-handed or Slice again, weak point is to need the player that the bar that uses number is inputed to the y of linear velocity that computing machine just can extrapolate ball to component, and is still convenient inadequately during use.
Fig. 2 is the synoptic diagram that fixed point is surveyed ball sensor, and as shown in Figure 2: this sensor adopts first device identical with the measuring staff sensor.Be provided with ball seat 9 on center line, point-source light or infrared transmitting tube are equipped with in the overhead about 300 centimeters places of ball seat, and all photosensitive tubes or infrared receiving tube are all in the place ahead of ball seat.Whether a pipe 8 (claiming to survey bulb) near ball seat is used to predict ball at ball seat.Whether be used to predict ball apart from ball seat two pipes 7 (claiming nearly row 2 villous themedas) slightly at a distance and fly out, and begin to clock, a row 6 farthest apart from ball seat, the pipe that is blocked when ball passes this comb represents the Z of ball to coordinate if having 29 pipes.This sensor can only measure ball the linear velocity vector Z to and X to component, and Y also number determines by the bar of player input number or by the bar of computer caddiecaddy prompting to component.The advantage of this sensor is simple in structure, and installation and maintenance are convenient, and shortcoming is, uses inconvenience, has needed the tame bar number imported.
Fig. 3 is a door case type sensor synoptic diagram, referring to Fig. 3: this kind sensor comprises the square frame 11 and 12 of two rectangles, the size of the size of square frame and projection screen 10 is basic identical, two flaps of each rectangular box are installed several infrared transmitting tubes and receiving tube respectively, same two horizontal sides are also pacified some infrared transmitting tubes and receiving tube respectively, in addition, also have amplifying circuit and data acquisition circuit to link to each other, and data acquisition circuit is connected with computing machine with receiving tube.Equipment in two rectangular box is identical.Rectangular box 11 is installed near the place of screen 10 and screen at a distance of about 25 centimeters, and rectangular box 12 is installed between batting district 13 and the rectangular box 11, with apart about 100 centimeters of rectangular box 12.The square stance ball passes square frame 12 earlier.This moment, timer began to clock, and write down the position coordinates by the infrared receiving tube that is blocked simultaneously.Can calculate thus ball through the Z on the plane, rectangular box 12 place to and Y to coordinate (Z
0, Y
0), when ball passed rectangular box 11, timer stopped timing, because sample frequency is fixed, the currency of this timer is just representing ball by passing rectangular box 12 to the required time dt of rectangular box 11, use with quadrat method can be regarded as out ball the Z on plane, square frame 11 place to and the coordinate (Z of Y
1, Y
1).Square frame 12 is constant to the distance of square frame 11, is made as DX, makes DY=Y
1-Y
0, DZ=Z
1-Z
0Three components that obtain the linear velocity vector of ball thus are
Vx＝DX/dt；Vy＝DY/dt；Vz＝DZ/dt。
The advantage of door case type sensor is that batting is convenient, and calculated amount is also few, and the batting Anywhere that ball is placed on beyond the rectangular box 12 all can obtain the initial line velocity vector, and next ball that hits is connected relatively good with the position of screen collision with visual ball.Shortcoming is: little speed may be surveyed to come out, and is not suitable for being used for the fruit mountain range and holes out; Size sensor excessive (outside dimensions about 4000 * 3000) is not easy to install and maintenance; Because projector can not change with player's batter's box, the image of demonstration has parallax; Can not expand the hyperchannel visual field; Striking point on the ball is far away to the distance of the rectangular box 12 of sensor generally speaking, has 2 meters far away approximately, and the speed of being measured by two square frames biography devices has not been the initial velocity of square stance like this, and the track of the ball that calculates thus has than mistake.U.S. a company will measure doorframe and be increased to three recently, can measure the initial acceleration of ball, and the error of the track of the ball that calculates thus will reduce greatly, but cost of products will improve.In addition,, to sensor could be arrived through after a bit of time after ball is hit, the delay of system responses will be increased like this because striking point on the ball is far away to the distance of the rectangular box 12 of sensor.
To sum up analyze, also there is following shortcoming in the indoor golf sensor at present:
(1) little speed may be surveyed to come out, and is not suitable for being used for the fruit mountain range and holes out;
(2) measuring error is bigger;
(3) need input bar number, use inconvenient.
