JP5177458B2 - Flying determination auxiliary device and flying determination auxiliary system using the same - Google Patents

Description

  The present invention relates to a flying determination auxiliary device for confirming flying determination in a start operation and a flying determination auxiliary system using the same device.

  In competitive sports, the superiority or inferiority of the starting action often has a decisive influence on the order of arrival.

  If the start operation is illegal earlier than others, it will not be a fair competition, so it is generally prescribed in the rules to disqualify.

  For example, in athletics, there is a 0.1 second rule, and if a start operation is performed 0.1 seconds before the start signal, the rule is disqualified. The competitor must remain stationary for 0.1 seconds from the start signal.

  When the start operation is performed within this stationary time, it is determined that the flying operation is performed. This flying determination is made by the referee by visual recognition. If a competitor protests against a flying decision made by the referee, it is recommended to prove the wrong start after the decision (see Article 150 of the Athletics Rules). This proof is often made by an unauthorized start detection device (not shown) or by reproduction of a video image of the start operation.

  The unauthorized start detection device is a device that mechanically detects an unauthorized start, detects the force applied to the block pedal when the athlete starts by an acceleration sensor or a pressure sensor via the rail, and detects the movement at the start operation. It is displayed with numerical values or graphics.

  According to this device, if the movement of the rail at the start of moving back and forth is fast or strong, it will be displayed as a large value, so you can make a flying decision immediately, otherwise make a flying decision May not be possible.

  For example, if you start with a load on your toes, start with a load upward, or if the athlete's weight is too light or the force to press the block pedal is extremely weak, If the directional force is not sufficiently transmitted to the rail, it is difficult to detect an illegal start.

  In addition, the fraudulent start detection device can make a flying determination with an accuracy of 1/1000 second, but it is very expensive and difficult to use in competitions where the operating cost cannot be applied.

  If a competitor determined to be "flying" protests this decision, if the competitor is not convinced by showing the data of the start motion accurately recorded by the unauthorized start detector, the proof is very It becomes difficult.

  With regard to video image playback, recent recording devices have improved image resolution, but recorded at a faster recording speed due to the slight movement of the competitors for the start action within the still time. When an image is played back frame by frame, it is extremely difficult for a referee to visually recognize an illegal start operation. Confirmation by the above reproduction is even more difficult when the athlete has little or slow movement, or when it is difficult to obtain the required illuminance such as cloudy or evening.

  Specifically, when a recording device is used, the error corresponding to the frame number interval decreases as the number of frames for recording (hereinafter, “frame” is referred to as “frame” and the number of frames is referred to as “frame number”) increases. To do. For example, when recording at a playback speed of 1000 fps, there is an advantage that the resolution is the same as that of the fraudulent start detection device, but the player's movement for 1/1000 second is small, so the recorded images are played one frame at a time. However, it is very difficult to specify the starting point of the movement. The above identification is even more difficult when there is little or slow movement of the competitor, or when it is difficult to obtain the necessary illuminance, such as overcast or evening.

  Competitors' protests for flying decisions are often made immediately after the competition. In such a case, taking the time to deal with the protest may interfere with the competition management.

  An object of the present invention is to solve the above-mentioned difficulties and to make clear and simple confirmation quickly when an illegal start is determined. In this way, it aims at contributing to quick competition management. Another object is to confirm unauthorized start at low cost.

In order to achieve the above object, the flying determination assisting device according to the present invention is a display device having a circuit for detecting a start signal, and the display device is configured to emit light in one color and in another color. The light emitting section of one color emits light up to a preset time simultaneously with the start signal, and the light emitting section of the other color emits light after a preset time has elapsed.

Further, in the flying determination auxiliary device according to any one of claims 1 to 5, the light emission color of the light emitting portion of the one color is red.
Further, in the flying determination auxiliary device according to any one of claims 1 to 5, the emission color of the light emitting unit of the other color is green.
The flying determination assisting system according to the present invention includes a flying determination assisting device, a recording device, and a playback device. The flying determination assisting device includes a circuit for detecting a start signal and a display device, and the display device is started. The recording device comprises a light emitting unit that emits light in one color until a preset time at the same time as the signal, and a light emitting unit that emits light in another color after the preset time has elapsed. The recording apparatus includes an apparatus that captures a moving image of the start image and records the captured image, and the reproduction apparatus includes an apparatus that reproduces the recorded image.
Further, in the flying determination assisting system according to claim 10, light emission by the display device is recorded in the same screen as the start image.
The flying determination assisting system according to claim 10, wherein the recording speed of the moving image is 100 fps to 200 fps.
Further, in the flying determination assisting system according to any one of claims 10 to 12, the light emission time of the light emitting portion of the one color is 0.1 second.

Further, in the flying determination assisting system according to any one of claims 10 to 12, the emission color of the light emitting unit of the other color is green.

The light emitting section 4 of one color that is turned on simultaneously with the start signal is lit for a preset lighting time T _1, for example, “0.1 second”, and after the lighting time T _{1 has} elapsed, the light emitting sections 5 of other colors. Is lit for a preset lighting time T _2, for example, “1 second”. During this time, each competitor is performing a series of starting actions. The lighting of the flying determination auxiliary device 1 and a series of start operations are captured by the recording device 25 as a moving image start image within the same screen.

Therefore, if there is a motion in the start image within the preset lighting time T ₁ of one color, it can be confirmed as an unauthorized start because it has moved within the “still” time on the rule. In other words, the unauthorized start confirmation according to the present invention is based on the fact that the motion within the still time can be visually recognized by the continuous reproduction of the framed image at an appropriate speed.

This “still” range is recorded with a change in emission color of one color of the light emitting unit 4 having one color at the start point t ₁ and the end point t ₂ and another color of the light emitting unit 5 having another color. Therefore, confirmation by visual recognition of the flying determination can be made clear and easy.

  And since the movement of this illegal start is reproduced in the image together with the emission of one color of the light emitting unit 4 of one color indicating the stationary time, the competitor has to admit his own starting operation of flying. I have to be convinced that this is an illegal start. Therefore, the risk of hindering competition management is prevented.

  In addition, a series of images in which light emission of one color is recorded immediately after the start is short and small, but since the light emitting unit 5 of other colors is lit, it serves as a mark for cueing the reproduced image. This makes it easy to find the flying determination point. This contributes to the speed of flying determination.

The main body 2 includes a start signal detection circuit 11, a start signal distribution circuit 13, lighting time control units 15 and 16, and light emitting element lighting drivers 17 and 18.

  The start signal detection circuit 11 is a circuit that detects a start signal generated from a start signal transmission device 21 to be described later. The start signal detection circuit 11 detects a start signal input from an input connector 9 provided on the bottom surface of the casing 7. Output to the start signal distribution circuit 13.

  The start signal distribution circuit 13 is a circuit that distributes a start signal, applies a start signal input from the input connector 12 to the A color light emission system and the B color light emission system, and uses a photo determination device (not shown) from the output connectors 14a and 14b.

The lighting time control unit 15 includes a CPU, and controls a lighting start point t ₁ and a lighting end point t ₂ of the A color light emitting unit. That is, a program is set in the lighting time control unit 15 so that the A-color light emitting unit 4 is turned on simultaneously with the start signal and is lit for “0.1 second”.

  The light emitting element lighting driver 17 is formed of a transistor, receives a command signal from the lighting time control unit 15, and supplies a voltage for lighting to the A color light emitting unit 4.

The lighting time control unit 16 includes a CPU, and controls a lighting start point t ₂ and a lighting end point t ₃ of the B color light emitting unit.

  In this embodiment, the light emitting element lighting driver 17 and the light emitting element lighting driver 18 are constituted by a transistor array. The lighting time control unit 15 and the lighting time control unit 16 are also shared by a single CPU.

  As shown in FIG. 3, the flying determination auxiliary device 1 according to the present invention is connected to an AC 100 V power source (not shown) and is connected to a start signal transmission device 21 by an electric wiring 31 for use.

  FIG. 3 shows a flying determination assisting system using the flying determination assisting device 1. The start signal transmission device 21 is a device that transmits a single-shot or continuous-type start signal, and the shape of the device is arbitrary, and may be a pistol type or a rectangular body. Reference numeral 25 denotes a recording device that captures the start operation of the competitor and records the photographed image. In the case of the present embodiment, the recording device 25 uses HiSpeed Exilim EX-FH100 made by CASIO. When recording at 120 fps by the recording device 25, it can be recorded as a 640 × 480 dot moving image, and in this case, an image of 11 to 12 frames can be obtained in 0.1 second. Reference numeral 27 denotes an SD card which is built in the recording device 25 and stores and saves captured images. Reference numeral 29 denotes a personal computer (PC), which reproduces an image stored and stored in the SD card 27.

  The flying determination auxiliary device 1 may be installed inside or outside the track 33 as shown in FIG. The installation location of the flying determination auxiliary device 1 is appropriately selected within a range that falls within the angle of view of the recording device 25. In this case, it is desirable to select the place where the competitor's upper body and legs are shown as appropriate so that the athlete can see the maximum. Furthermore, as shown in FIG. 4 (B), it may be installed both inside and outside the track 33. In the case of a 100m competition or a 110m hurdle competition, it is generally installed inside the track 33.

  Next, the operation of the flying determination auxiliary apparatus 1 will be described based on the timing chart shown in FIG.

  First, a start signal transmission device 21 (shown in FIG. 3) electrically connected to the flying determination auxiliary device 1 is operated by a judge, and a start signal is generated.

  When the start signal is applied to the input connector 9 (FIG. 5 <1>), the start signal detection circuit 11 detects the start signal (FIG. 5 <2>).

  In response to the start signal, the start signal distribution circuit 13 is applied (FIG. 5 <3>), the lighting time control unit 15 is activated, and an ON signal is issued to the light emitting element lighting driver 17 (FIG. 5 <4>).

The light emitting element lighting driver 17 is turned on by the ON signal (<5> in FIG. 5), and the red A light emitting section 4 emits light for “0.1 seconds” which is a preset lighting time T ₁ (FIG. 5). 5 <6>, FIG. 6).

Next, when “0.1 second” which is a preset lighting time T ₁ has elapsed, the signal input to the lighting time control unit 15 falls and issues an OFF signal (<7> in FIG. 5).

  As a result, the light-emitting element lighting driver 17 is turned off, and the red A-color light emitting unit 4 is turned off (<8> in FIG. 5).

  At the same time as the lighting time control unit 15 is turned off, the lighting time control unit 16 is activated by a signal (FIG. 5 <9>) and issues an ON signal to the light emitting element lighting driver 18 (FIG. 5 <10>).

The light emitting element lighting driver 18 is turned on by the ON signal, and the green B light emitting unit 5 emits light for “1 second” which is a preset lighting time T ₂ (FIG. 5 <11>, FIG. 6).

Next, when “1 second” which is a preset lighting time T ₂ has elapsed, the signal input to the lighting time control unit 16 falls and issues an OFF signal (<12> in FIG. 5).

  As a result, the light emitting element lighting driver 18 is turned OFF, and the green B light emitting section 5 is turned off (<13> in FIG. 5).

  In the above-described series of light emission steps, the athlete performs a start operation as shown in FIGS. 7 (A) to 7 (C).

  The start signal is also output from the output connector 14a and the output connector 14b by the start signal distribution circuit 13 to an unauthorized start detection device and a photo determination device (not shown). The fraud start detection device is used for official recording of flying detection, and the photo determination device is used for photo determination and time measurement at the goal.

  In the operation of the flying determination auxiliary device 1, as shown in FIGS. 3 and 6, the start operation of the athlete is taken by the recording device 25. This shooting can be performed by a recording device 25 such as HiSpeed Exilim EX-FH100 manufactured by CASIO, which is available at a low cost, and is recorded and stored in the SD card 27 as a framed moving image.

  Then, the recorded image recorded and stored in the SD card 27 is reproduced by a personal computer (PC) 29 to visually recognize the start operation of each competitor.

FIGS. 7A to 7C are images obtained by reproducing the moving image by a personal computer (PC) 29. 7A is the first frame of the framed moving image, FIG. 7B is the last frame of the lighting time T ₁ of the A color light emitting unit 4, and FIG. lighting time of the B color luminescent portion 5 to be turned is first frame of T _2. Actually, in this example, there are 11 to 12 frames from the first frame shown in FIG. 7A to the final frame shown in FIG. 7B.

  If it was determined to be flying, if there was movement in the series of start images taken in FIGS. 7A and 7B, it moved within “0.1 second”, which is the “still” range. Therefore, it can be confirmed as an illegal start. That is, the confirmation of the illegal start according to the present invention is based on the fact that the framed start image is continuously reproduced at an appropriate speed so that the movement in the stationary time can be visually recognized.

The “still” range on the rule is “before 0.1 second”. Theoretically, even if there is a player's movement before the start point t ₁ of the A-color light emitting unit 4, it is flying, but 0 When there is a player's movement before 1 second, it is usual that there is a player's movement between the start point t _{1 and the} end point t ₂ of the A-color light emitting unit 4 following this.

  Since the player's movement immediately after the start of the start operation is slight, it is difficult to visually check whether or not the start image recording a series of start operations is moving in each frame. However, in the above embodiment, since the start operation is framed as a moving image, when played continuously at an appropriate speed by the personal computer (PC) 29, the flying game is performed according to the principle of “parapara anime”. Since the athlete appears to be moving, the athlete's movement is easily and clearly visible.

  For example, in FIG. 7 (A) and FIG. 7 (B), the athlete in the second lane moves from the shoulder to the lower arm and waist as shown by the solid line in FIG. 7 (B) (FIG. 7 (A)). 7B), it is difficult to see whether this movement is moving in each frame of the start image, but this is continuously performed at an appropriate speed. Since it seems to move when played back, it is easy and clear to see. In addition, in FIG. 7 (A) and FIG. 7 (B), there is no movement in other players. The movement of the player in the second lane in FIG. 7B is exaggerated, but the actual movement is much smaller.

In reproducing the recorded image, as shown in FIG. 6, the A light emitting section 4 is lit red at the start point t ₁ and end point t ₂ of the prohibited range of the start operation, and thereafter from t _{2 to} t ₃ . The B light emitting unit 5 is lit in green. As described above, the recorded image is recorded and reproduced with a change in the light emission color of the red light emission of the A color light emission unit 4 and the green light emission of the B color light emission unit 5, so that confirmation by visual recognition of the flying determination can be made clear and easy. it can.

  Since the movement of this illegal start is reproduced in the image together with the red light emission of the A-color light emitting unit 4 indicating the stationary time, the competitor has to admit his own flying start operation, and is convinced that the illegal start. It must be. Therefore, it can be expected that the protest of the flying determination by the athlete will be convinced at an early stage.

  Thereby, it can contribute to quick competition management.

  Moreover, according to the said embodiment, the head of a flying determination location can be performed easily as follows.

  That is, as shown in FIGS. 7A to 7C, since the red light emission time by the A color light emitting portion immediately after the start is as short as “0.1 seconds”, the green B color If the light emitting unit 5 is not turned on, it is very difficult to cue the reproduced image. However, according to the above embodiment, there is no such fear.

  In other words, in the cueing of the reproduced image for confirming the fraud start determined as “flying”, if a spot where the green B-color light emitting unit 5 that is lit for 1 second is found is lit in red immediately before that. This is the prohibited range of the start operation to be confirmed, and it is possible to confirm whether or not it is an illegal start by reproducing an image of only a series of frames in this prohibited range.

  Therefore, the light emission by the B-color light emitting unit 5 has an effect of serving as a mark when cueing a reproduced image for confirmation of flying determination.

  Thereby, it contributes to the quickness of the confirmation of flying determination.

  Here, based on FIG. 8, the photographing conditions of the recording device 25 and the simultaneous lighting images of the A color light emitting unit and the B color light emitting unit will be described. Since the shutter speed and start signal of the recording device 25 are asynchronous and the shutter is opened and closed at equal intervals, depending on the shooting conditions such as the shutter speed, as shown in FIG. In some cases, an image in which both the red color by 4 and the green color by the B-color light emitting unit 5 are lit simultaneously is taken.

  This occurs because light emission of both colors is recorded in one frame at the moment when the lighting is changed from the A color light emitting unit 4 to the B color light emitting unit 5 during the shutter “open”.

  Such a “simultaneously lit image” has a high frequency when the shutter release time is long (that is, the shutter speed is slow).

Such a “simultaneously lit image” includes an image after the flying target time T ₁ , and is therefore handled as a target for confirmation of unauthorized start.

  Even if about one frame is removed by such handling, the confirmation of the illegal start according to the present invention is the visual recognition of the motion by continuous reproduction of the framed image at an appropriate speed, so that it substantially affects the judgment. Not give.

  The flying determination assisting apparatus 1 according to the present invention and the flying determination assisting system using the apparatus are not limited to the above-described embodiments. For example, the flying determination auxiliary device 1 may be configured in a circuit configuration without providing the start signal distribution circuit 13 as shown in FIGS. 9 and 10. Such an embodiment is advantageous, for example, when a tournament operation such as a junior high school or high school tournament in which an unauthorized start detection device may not be used must be performed at a low cost. The operation order of <1> to <12> in the timing chart of FIG. 10 is the same as <1>, <2>, and <4> to <13> of FIG.

  In the embodiment of FIG. 2, a plurality of recording devices 25 can be branched and connected to the start signal distribution circuit 13. In such a case, it is advantageous to photograph the start operation of the athlete from various angles.

  By connecting the recording device 25 and the personal computer (PC) 29 via USB, the captured moving image can be transmitted to the personal computer (PC) 29 online and played back. It is experientially efficient to prepare a plurality of recording devices 25 and SD cards 27 and exchange them between competitions.

  Further, in order to obtain the number of recorded frames necessary for confirmation of unauthorized start according to the present invention, it is desirable to be able to shoot about 100 to 200 fps. However, the flying determination auxiliary device according to the present invention can cope with a higher reproduction speed of 1000 fps.

  The start signal detection circuit 11 can be appropriately configured.

  The colors of the A color light emitting unit 4 and the B color light emitting unit 5 are arbitrary as long as they are different.

The light-emitting element lighting drivers 17 and 18 may be formed of separate transistors instead of the transistor array. Further, the program control of the preset times t ₁ , t ₂ , and t ₃ of the A color light emitting unit 4 and the B color light emitting unit 5 by the CPU can be performed by a hard logic circuit. Further, the output connector 10 and the input connector 12 can be connected by wiring in the control board.

  The flying determination auxiliary device according to the present invention can be used as, for example, an athletic equipment.
