Description

  The present invention relates to a technique for positioning a ball or the like used in a sports competition using a satellite positioning system to improve competition determination, sports technique, and watching fun.

Conventionally, in baseball and the like, the speed of the ball thrown by the pitcher has been measured with a measuring instrument, but the trajectory of the ball has been determined by image analysis or visual measurement by an expert. I came.
Most of the measurements by sports machines were photography or laser sensors. For example, in competitions that compete for ranks such as bicycle races, horse races, and 100-meter runs, the rank is objectively determined by continuous photography at the goal point. Similarly, in competitions for speed, time was measured at the timing when the laser beam at the goal point was blocked. Whether a tennis ball is on or off the line is also applied by applying image recognition technology based on video.

  Recently, wristwatch-type motion sensors and the like have also appeared for general consumers, but the information collected is human information.

  JP2016-163627A

However, in the conventional technology, information that contributes to the final judgment such as the order, time, and relationship with the line is measured by the machine and can be used, but the three-dimensional position information up to that is measured by the machine. It never happened.
In competition and sports, the results are important, but the process leading to the results is the content that spectators can enjoy. However, spectators can observe the process with the naked eye, but they cannot observe subtle differences because it is possible with the naked eye. Sports and competitions are for appreciating human power, and if this subtle difference can be observed, the attractiveness of watching sports will be further increased, and the person himself / herself will be objective. Observing the situation can also help overcome the problems.

  In addition, the final judgment such as ranking, time, strike or ball can be made more precisely.

  On the other hand, there is a system for searching for a golf ball fall position using a positioning satellite as in Patent Document 1, but it is not such as outputting a movement trajectory.

  The present invention continuously outputs a positioning signal constantly receiving unit for receiving a positioning signal from a satellite positioning system at least in a part of a time zone in which a competition is performed, and position information based on the received positioning signal. A competition ball having a position information wireless output unit;

  A position information acquisition unit that continuously acquires the position information that is continuously wirelessly output, a movement locus acquisition unit that acquires a movement locus of a game ball based on the acquired position information, and an output of the acquired movement locus A movement trajectory output system for a game ball, comprising: a movement trajectory output device having a movement trajectory output unit, is proposed.

  Balls for competition include, for example, baseball, billiards, bowling, gateball, lacrosse, dodgeball, kick baseball, golf, handball, flying disc, ultimate, guts, disc golf, volleyball, faust ball, Indiana, basketball, water basketball, Netball, korfball, portball soccer, futsal, rugby, American football, cricket, softball, Pesapallo, tennis, paddle tennis, ju de porm (real tennis), table tennis, badminton, squash, tambeach, tumblr, tumbler, Includes competition balls such as speed minton, racquetball and hirai.

  Other examples of competition balls include archery and archery competition arrows, competition packs used for ice hockey, curling competition stones, badminton competition shuttles, throwing competitions, cannonballs, discus A competition disk can be mentioned.

These competition balls, archery and archery competition arrows, competition packs used for ice hockey, curling competition stones, badminton competition shuttles, throw throw competitions, cannon throw competition rounds, disc throw competition discs, etc. Has a power source for driving each unit (satellite signal receiving unit, satellite signal radio output unit, immediate information generation unit, positioning information radio output unit). The power source is a non-contact charge type power source or a no power source. An external radio wave excitation type power source may be used like an RF tag.
Further, these game balls and the like may be provided with a small microphone, a temperature sensor, a gravity sensor, and the like in order to collect further information. It is preferable that data from a small microphone, a temperature sensor, a gravity sensor, etc. is also stored in real time or once and wirelessly output to the outside. Information from a small microphone, temperature sensor, gravity sensor, etc. can be used to generate impact magnitude, impact location such as a ball, and rotation information such as a ball. Until these can be used alone as analysis information, the sensing results and the magnitude of impact, impact location, rotation information, etc. are measured with a separate measuring means and the causal relationship is clarified using artificial intelligence etc. It is also possible to use it.

  Further, it is conceivable that the balls are provided with a sensor for detecting the movement state of the person from the hand of the person who contacts the ball. Pulse sensors, odor sensors, blood glucose level sensors, etc. This also makes it possible to collect physical information about the players who compete.

According to the present invention, balls that could not be measured with conventional techniques, archery and archery competition arrows, competition packs used for ice hockey, etc., curling competition stones, shuttles for badminton competitions, throwing competitions, shot throwing competitions It is now possible to measure the movement trajectory during competitions such as cannonballs and discs for disc throwing as 3D position information.
This makes it possible to observe time-position information of balls, etc. that cannot be grasped by the naked eye such as spectators and judges, and if this is provided to spectators, the attraction of sports watching will increase, and the person who is competing Observing yourself objectively can help you find and overcome problems to improve your competitive ability. Also, if it is provided to the referee, the final decision on whether it is a strike or a ball can be made more precisely.

There are cases of 2D information and 3D information. However, in some cases, a signal from a positioning satellite may be included. The same applies hereinafter.) A movement locus output unit that outputs 0206 is included. The main terms and configuration will be described below.

  <Description of Configuration of Embodiment 1>

<Description of presupposed configuration>
"Positioning satellite" is a satellite used in a satellite positioning system. A system that uses a receiver that receives signals from multiple positioning satellites (a type of artificial satellite) that transmits signals to an unspecified number of people on the ground. Refers to the position measurement system.

  A typical function is to know the position of an object in association with time (time) on the ground surface or in the air by receiving radio waves from a positioning satellite system. Representative positioning satellite systems include GPS, GLONASS, Hokuto, and Galileo, but Japan's Quasi-Zenith Satellite Michibiki started operating the system in four units in 2018, and succeeded the first in 2020. It has been decided that one satellite and three satellites will be added in 2023 to operate in a seven-body system. GPS currently used most in Japan has a position measurement error of several meters, but Michibiki has already provided correction information with accuracy of 1cm class by private services for the whole country of Japan. Position-time information such as balls is available and sufficient.

  <Description of the configuration provided for the ball for competition>

  The “positioning signal constant reception unit” is configured to be able to always receive a positioning signal from a positioning satellite at least in a part of a time zone in which a competition is being performed. “Continuous reception” indicates that the reception is not performed only when the ball stops. The object of the present invention is to output a movement trajectory during a game such as a game ball as three-dimensional data or as a three-dimensional image, and is not intended to determine the location of the ball. Therefore, it is completely different from the invention for acquiring the position information of the golf ball of the prior art. It is preferable that the positioning signal is received at all times by a radio signal command from outside the playing ball to the positioning signal constant receiving unit. Since it is a competition ball, the outer surface of the ball should not be unsuitable for competition, especially when the ball standard is defined by the official rules of competition, There must be. Since the outer surface is a surface that can be grasped with a hand or hit with a tool in a competition, it is inconvenient if any part is exposed, so instructions for the competition ball will be issued wirelessly to each part stored inside Configure. Since the positioning signal constant reception unit receives so that the position information can be calculated from the positioning signal, it must be configured to always receive signals of a plurality of positioning satellites at the same time.

  A part of the reception function of the positioning signal constant reception unit is constituted by an antenna. The antenna is a chip type having a thickness of about several millimeters × several millimeters and a thickness of about 1 millimeter. Since the ball or the like rotates in some cases, the antenna may not always be oriented in an appropriate direction. For example, if the ball is a ball, the antenna is arranged in six directions near the center of the ball (up, down, front, back, left, and right with any direction up). It is conceivable that the receiving surface is arranged. The receiving surface of the antenna does not necessarily have to be a six-sided arrangement, and may be any number of polyhedrons as long as it is a polyhedron and can be arranged equally in each direction. A polyhedron according to Euler's polyhedron theorem is conceivable. A satellite signal receiving chip is connected to the antenna. Satellite signal receiving chips are also becoming smaller in size and can be several millimeters square and about 1 to 2 millimeters thick. Therefore, a plurality of satellite signal receiving chips are arranged near the center of a ball or the like according to the antenna.

  The positioning signal constant reception unit delivers the received positioning satellite signal to the position information wireless output unit.When there are multiple antennas, the signal with the highest received intensity or the lowest noise intensity among each antenna is received. It is preferable to select and output. Therefore, the positioning signal constant reception unit may have an optimum signal selection unit that performs such a function.

  The “position information wireless output unit” continuously wirelessly outputs position information based on the received positioning signal. Since the received positioning signal is output from the positioning signal constant receiving unit, it is acquired. The position information wireless output unit may be the positioning signal itself as the position information, or may be a signal obtained by processing the positioning signal by processing the positioning signal. The position information wireless output unit continuously outputs position information wirelessly, and this continuous transmission includes intermittent transmission with a short interval. The interval is about 1 to 50 times per second, preferably about 5 to 30 times per second, and more preferably about 10 to 30 times per second. This is because if the interval is too large, the resolution of the movement trajectory will be insufficient, and if the interval is too small, the center position before movement of the ball will be included in the area of the ball after movement, resulting in excessive information. In addition, the position information wireless output unit may include a holding unit that holds the received positioning signal, batch processing the positioning signal for several seconds, and collectively output the batch processed position information. Good. The wireless output of the batch-processed position information may be an information amount enough to acquire a ball movement trajectory for several seconds, or may be an information amount enough to acquire a ball movement trajectory of about several tens of minutes. When the amount of information is sufficient to obtain a movement trajectory of several tens of minutes, the information is output according to a wireless command from the outside of the ball, and in addition to or instead of the continuous wireless output of the position information wireless output unit Functions and means. Further, the position information wireless output unit may be configured to wirelessly output by adding various sensor information described later.

  The transmitting antenna of the position information wireless output unit is a flexible band-shaped or comb-shaped or spiral-shaped thin antenna that is wound around almost the entire surface of a spherical core member such as a ball or a spherical base member. Deploy. This is to allow a sufficient distance for transmission. However, it is designed so that interference with the satellite signal receiving antenna does not occur.

  “Drive power” is included in the ball to supply power to each part of the ball. The drive power supply is preferably capable of non-contact power reception as described above. The coil for non-contact power reception (non-contact charging) must be arranged so as not to interfere with the satellite signal receiving antenna or the transmitting antenna. Further, it is preferable that information indicating the arrangement direction and the arrangement position of the balls during non-contact power reception (non-contact charging) as viewed from the appearance of the ball or the like is displayed in a visible manner. For example, it is conceivable to draw a circle on the ball and systematize the circle to match the spherical depression of the non-contact charging device.

  Note that the position information may include information other than information related to the position. Examples include the charging ratio of the power supply of the game ball, failure information of each part provided in the game ball, or failure prediction information, sensing information from various sensors (impact sensor, acceleration sensor, rotation sensor, temperature sensor), etc. It is.

  <Configuration provided in the moving locus output device>

  The “position information acquisition unit” continuously acquires the position information that is continuously wirelessly output from the game ball. The acquired position information is output for use by the movement trajectory acquisition unit.

  The “movement locus acquisition unit” acquires the movement locus of the game ball based on the acquired position information. The movement trajectory of the game ball is three-dimensional information and is represented by three-dimensional coordinates on the earth. For example, longitude, latitude, and height from the ground (or height from the earth standard surface).

  The “movement locus output unit” outputs the obtained movement locus. This is because it is used by the participants of the competition and the spectators of the competition. The output destination may be a server system of a stadium operator, a mobile terminal of a spectator, a large screen of a stadium, a broadcasting device, a recording device, or an Internet browsing system.

  <Moving track output system>

As described above, the movement locus output system includes the game ball and the movement locus output device.

The “competition field” is a ground such as a soccer field, a baseball field, or a tennis court and surrounding structures (goals, home run spaces, nets, etc.), basketball floors and goals, badminton floors and nets, table tennis This refers to the three-dimensional area necessary for appreciating the competition as meaningful, such as the platform and net, bowling lane and pin, and these aerial areas.
<Embodiment 3>

  <Overview of Embodiment 3>

  In the present embodiment, the movement trajectory of the game ball can be viewed in the 3D image of the game field.

  <Configuration of Embodiment 3>

  The third embodiment is an embodiment based on the second embodiment. The game ball movement trajectory output system of the second embodiment further includes a competition field 3D data holding unit, a 3D image acquisition unit, and a 3D image output unit. It has a stadium system.

  <Description of Configuration of Third Embodiment>

  The “competition field 3D data holding unit” is configured to hold the 3D data of the competition field including information representing the meaning in the competition in relation to the position of the competition ball during the competition. 3D data of the competition field includes VR (Virtual Reality) AR (Augmented Reality), MR (Mixed Reality), SR (Alternative Reality: It is desirable that the data be configurable as one or more of Substitutional Reality (sa). This data may include the current stadium dynamic data acquired by a 3D camera and converted into 3D data. In order to dynamically acquire the 3D data of the stadium from the 3D camera, it is preferable to install a plurality of 3D cameras in the stadium so that the competition field of the stadium can be seen from a bird's eye view. The competition field 3D data may include 3D data of competition participants. The 3D data of the competition participants may be composite data or live-action data.

  The “3D image acquisition unit” uses the competition field 3D data and the movement trajectory output from the movement trajectory output device, based on the 3D data including the competition field and the competition ball moving in the competition field. It is configured to acquire a 3D image. The 3D data may be stored in a 3D data storage unit, and a 3D image may be acquired (configured) and output in response to a request.

The “3D image output unit” is configured to output the acquired 3D image. The 3D image output unit can use an image with a sense of presence when it has viewpoint information dissimilar output means that can output a 3D image according to viewpoint information from an operator of the server or a user of the terminal. Further, it is preferable that the 3D image can be subjected to slow playback, fast forward playback, still image playback, and the like, and the viewpoint position can be moved according to the viewer's request during each playback.
<Embodiment 4>

  <Outline of Embodiment 4>

    The present embodiment is based on the second and third embodiments, and the game field is a plate-like surface (for example, a table tennis table surface), a floor surface (for example, a table tennis table periphery, a basketball floor surface, a bowling lane) or the ground. The position information acquisition unit includes an antenna that receives a position information signal output from the position information wireless output unit of the game ball on the board surface, the floor surface, or under the ground. A stadium system having antenna means.

  <Configuration of Embodiment 4>

  The competition ball basically moves on the competition field, but if an antenna is installed on the competition field, it becomes an obstacle to competition. On the other hand, it can be arranged in a position where the competition feel can be expected. However, the power that can be used by the game ball is not so large, so if you can reliably receive weak radio waves from the game ball, you can't go beyond this. Therefore, an antenna and antenna peripheral members are arranged so as not to interfere with the competition under the competition field. This is because even if the intensity of the radio wave transmitted from the game ball is relatively weak, it can be received well. When the competition field is wide, it is possible to divide a plurality of antennas into several blocks.

<Description of Configuration of Fourth Embodiment>
The “competition field” is an area where a game is performed using a ball and, in some cases, an adjacent area. In this embodiment, an antenna is installed below the competition field. Therefore, in a baseball stadium, a soccer stadium, an American football stadium, a rugby stadium, a tennis court, etc., it is configured so that metal structures such as drainage facilities are not arranged.
“Antenna means” includes the antenna itself. In addition to the antenna itself, an amplifier for a signal received by the antenna, a transmission circuit for the amplified signal, and an antenna switching circuit that is active when a plurality of antennas are arranged may be included.
The “antenna” needs to be excellent in impact resistance, water resistance and heat resistance, and a thin antenna covered with a flexible material and a plastic having a low water vapor permeability is suitable.
“Antenna coating materials” include PE polyethylene with excellent moldability, chemical resistance, electrical insulation, and water resistance, as well as slidability, mechanical properties, electrical properties, chemical resistance, impact resistance, and heat resistance. Excellent PET polyethylene terephthalate, aramid sheet, aramid pulp, etc. are suitable.

  <Embodiment 5>

  The present embodiment is based on the third or fourth embodiment, and the 3D image output unit of the game ball movement trajectory output system includes VR (virtual reality), AR (augmented reality), MR (mixed reality), SR ( It is a stadium system having virtual output means which is one or more output means of (alternative reality).

For example, there are cases where it is better to use CG instead of live action in order to allow the viewer to watch the movement trajectory of the game ball with a sense of reality. When displaying the 3D space including the player in the movement trajectory of the competition ball, it is better to display not only the movement trajectory of the ball but also the movement and expression of the athlete's body in 3D. However, since it may be difficult to 3D display the movement of a live-action player from any viewpoint, it may be possible that the player mixes the game field with CG and live-action. Since the competition field normally does not move, the live-action information is acquired and held in a state where no one is in the stadium. In addition, an actual image of the game ball may be used, or a CG image may be used.
<Embodiments 6, 7, 8>

  The embodiment described above is a case using a competition ball, but instead of a competition ball, a competition arrow, a competition pack, a curling competition stone, a badminton competition shuttle, a throwing competition, a cannonball competition cannon, The moving locus output system according to the first embodiment, which is any one of the disc throwing discs, is proposed.

Alternatively, instead of the competition ball, any one of the competition arrows, the competition pack, the curling competition stone, the badminton competition shuttle, the throwing competition, the cannonball competition round, and the disc throwing competition disk from Embodiment 2 A stadium system according to any one of the fifth embodiment is proposed. In addition, we propose a competition method and a performance method using the aforementioned stadium system.
<Other embodiment 1>

  The stadium antenna is configured to transmit a control signal for controlling each part disposed on the ball, and the ball is configured such that each part disposed on the ball is controlled according to the control signal. It is also possible to do. For example, the protocol of the signal transmitted from the balls, the redundancy, the signal retransmission request, the adjustment of the signal output, the change of the used frequency band, the drive command for the spare function, and the like.

This is because the communication environment is easily influenced by the weather and the surrounding environment, particularly in the case of an outdoor stadium. Weather and surrounding environment include temperature, humidity, ball wetness, ball dirt, stadium floor / ground wetness, types and amounts of materials that make up the floor / ground, and other types of surroundings Can be mentioned.
<Other embodiment 2>

  According to the present invention, 3D data of the movement trajectory of the game ball can be acquired. It is conceivable that this 3D data is applied not only for ornamental purposes but also for video games. In some video games, the actual name of the team and the actual players can be used as CG, but for example, a pitcher throws a ball that exists as data created in a computer and uses actual data. Absent. Therefore, by using the movement trajectory of the game ball acquired by the present invention without using a video game, it is possible to enjoy a video game with a sense of reality that is closer to reality. This is the same not only for baseball but also for any sport such as soccer, tennis, or golf.
