[0003] A light wave distance meter may be used for measurement in track and field competitions.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the conventional technology has a problem in that it may not be possible to efficiently obtain records of track and field competitions.

[0006] A conventional light wave distance meter can only obtain records of one pit at a time. Therefore, when a competition is held at multiple pits, it was necessary to prepare a light wave distance meter for each pit.

[0007] On one hand, it aims to efficiently obtain records of track and field competitions.

Means for Solving the Problems

[0008] In one embodiment, the measuring device includes an acquisition unit that acquires a plurality of positions identified using one optical distance meter, and a position of a target to be measured that is identified using the optical distance meter but is different from any of the plurality of positions, and a calculation unit that calculates the distance between at least one of the plurality of positions and the position of the target to be measured. [Effects of the Invention]

[0009] According to one method, it is possible to efficiently obtain records in track and field events. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] Hereinafter, embodiments for implementing the measuring device, measuring method, and measurement program according to the present disclosure (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings. Note that the present disclosure is not limited by these embodiments.

[0012] One of the objectives of this embodiment is to efficiently obtain records of track and field events.

[0013] [Configuration of Embodiment] FIG. 1 is a diagram for explaining the operation of the measuring device according to the embodiment. As shown in FIG. 1, the measuring device 10 is installed at a position where it can measure the distance in the pit provided in the stadium of track and field events. In the embodiment, one measuring device 10 is installed for a plurality of pits (pit 50a and pit 50b). Here, the pit is the place where the athlete lands in jumping events such as long jump and triple jump.

[0014] As shown in FIG. 1, in the stadium, there are a sandpit 51, a switchboard 52a for pit 50a, and a switchboard 52b for pit 50b. The athlete competes in either pit 50a or pit 50b. The measuring device 10 can measure the records in both pit 50a and pit 50b.

[0015] The measuring device 10 measures the distance from its own position to the position where the prism marker is installed and the angle of the position where the prism marker is installed with respect to its own position. Thereby, the measuring device 10 can specify the relative position of the point to be measured as coordinates and obtain the distance between points by calculation.

[0016] Although the measuring device 10 can specify the position as three-dimensional coordinates of the plane XY axis and the height Z axis, in the embodiment, the position is represented by the coordinates of the plane XY axis, and the Z axis is not considered.

[0017] In this context, the record for jumping events is the distance from the starting point to the landing point. The starting point is determined based on a base point on the takeoff board. As shown in Figure 1, base points 501a and 502a are the two vertices on the sandpit 51 side of the rectangular takeoff board 52a. The measuring device 10 identifies the midpoint between base points 501a and 502a as the starting point 503a. The measuring device 10 stores the position of the starting point 503a.

[0018] Furthermore, the measuring device 10, in the same way as with pit 50a, identifies the starting point 503b for pit 50b based on the base points 501b and 502b of the crossing board 52b. At this time, the measuring device 10 stores the position of the starting point 503b. In other words, the measuring device 10 stores the positions of both the starting point 503a and the starting point 503b.

[0019] Let's assume that a trial run is performed in pit 50a and the athlete lands at landing point 504. The measuring device 10 measures the distance from the starting point 503a to the landing point 504 as the record of the trial run in pit 50a.

[0020] Furthermore, the measuring device 10 determines a straight line 511a that passes through the starting point 503a and is perpendicular to the straight line connecting the base point 501a and the base point 502a. The straight line 511a is used to determine whether or not the player's landing point is within the range corresponding to the pit 50a.

[0021] Furthermore, suppose a trial is performed in pit 50b and the athlete lands at landing point 505. The measuring device 10 measures the distance from the starting point 503b to the landing point 505 as the record of the trial in pit 50b. In this way, the measuring device 10 can measure records from multiple pits with a single unit.

[0022] The measuring device 10 then determines a straight line 511b that passes through the starting point 503b and is perpendicular to the straight line connecting the base point 501b and the base point 502b. This straight line 511b is used to determine whether or not the athlete's landing point is within the range corresponding to the pit 50b.

[0023] Figure 2 shows an example of the configuration of a measuring device according to an embodiment. As shown in Figure 2, the measuring device 10 includes a light-emitting unit 11, a light-receiving unit 12, an input unit 13, an output unit 14, a storage unit 15, and a control unit 16.

[0024] The light-emitting unit 11 emits a laser such as infrared light. The light-receiving unit 12 receives the laser reflected by the prism marker. The light-receiving unit 12 may also include a distance measuring sensor that measures distance using a TOF (Time of Flight) method, and an optical transit that measures angle.

[0025] The input unit 13 is an interface connected to input devices such as keyboards, touch panels, and mice. The output unit 14 is an interface connected to output devices such as displays and speakers.

[0026] The memory unit 15 is a storage device such as flash memory and NVSRAM (Non-Volatile Static Random Access Memory). The memory unit 15 stores competition information 151 and registration information 152.

[0027] Competition information 151 is a means of identifying the starting point for each competition event. For example, competition information 151 includes a program that calculates the coordinates of the starting point as the midpoint between the coordinates of two reference points, as a means of identifying the starting point associated with the competition event "long jump".

[0028] Registration information 152 is registered information necessary for measurement. For example, registration information 152 includes the coordinates of the starting point associated with each of the multiple pits.

[0029] The control unit 16 controls the entire measuring device 10. The control unit 16 is, for example, a CPU (Central Processing Unit), MPU (Micro Processing Unit), GPU (Graphics Processing Unit), ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), etc.

[0030] The control unit 16 refers to the programs and data stored in the storage unit 15 and executes various processes. The control unit 16 also functions as various processing units through the operation of various programs. The control unit 16 includes an acquisition unit 161, a calculation unit 162, a determination unit 163, and an output control unit 164.

[0031] Here, the part including the light-emitting unit 11 and the light-receiving unit 12 is referred to as an optical distance meter. The measuring device 10 itself may be an optical distance meter. Also, some functions of the control unit 16 may be independent of the optical distance meter. For example, a computer connected to the optical distance meter may function as the control unit 16. In that case, the computer uses the position obtained from the optical distance meter to perform the processes described later.

[0032] The acquisition unit 161 acquires multiple locations identified using one optical distance meter, and the location of a measurement target identified using the optical distance meter, which is different from any of the multiple locations. For example, the multiple locations are the starting points of multiple pits. Also, for example, the location of the measurement target is the position where the athlete landed.

[0033] The calculation unit 162 calculates the distance between at least one of a plurality of locations and the location of the object to be measured. For example, the calculation unit 162 assumes a triangle with the starting point, the position of the optical distance meter, and the location of the object to be measured as its vertices, and calculates the distance.

[0034] Based on the distance between the first position among the plurality of positions and the position of the measurement target, the determination unit 163 determines whether the position of the measurement target is included in the area corresponding to the first position. Here, an example of the area setting method will be described.

[0035] (Method of setting an area based on the distance from a straight line) Based on the distance between the straight line based on the first position and the position of the measurement target, the determination unit 163 can make a determination.

[0036] The position of the landing point 504 in FIG. 1 is the position of the measurement target. The position of the straight line 511a is the position based on the starting point 503a which is the first position. The determination unit 163 calculates the distance Da between the straight line 511a and the landing point 504. Also, the determination unit 163 calculates the distance Db between the straight line 511b and the landing point 504. If Da < Db, the determination unit 163 determines that the landing point 504 is included in the area of the pit 50a. Also, if Da > Db, the determination unit 163 determines that the landing point 504 is included in the area of the pit 50b. The determination unit 163 can make the same determination for the landing point 505 as well.

[0037] In the example of FIG. 1, since Da < Db, the determination unit 163 determines that the landing point 504 is included in the area of the pit 50a. Also, in this case, the distance between the landing point 504 and the starting point 503a becomes the record of the skill in the pit 50a.

[0038] In this way, the determination unit 163 determines that the position of the measurement target is included in the area corresponding to the position among the plurality of positions that has the minimum distance from the position of the measurement target.

[0039] For example, it is assumed that the measurer may misidentify which pit among the plurality of pits the trace of the sand pit where the athlete landed was used for the skill. According to the measuring device 10, based on the starting point of each pit, automatic determination of the pit where the skill was performed or alerting the measurer can be performed.

[0040] While the size of the sandpit is defined in track and field rules, it is not fixed. Therefore, precisely calculating the coordinates of the measurement area can be difficult. Even in such cases, the measurement device 10 can determine the location of the trace based on which pit it is closest to.

[0041] (Method for defining a region with a predetermined shape) The acquisition unit 161 acquires the position of the region corresponding to the pit 50a. The determination unit 163 determines, based on the acquired position of the region, whether or not the landing point 504 is included in that region. Specifically, the acquisition unit 161 may acquire the position of each vertex of region 53a, assuming that the pit 50a is a rectangular region 53a. It is not necessarily required to acquire the position of all vertices. Based on the acquired position of each vertex, the determination unit 163 sets a rectangular region 53a as the region corresponding to the pit 50a. Region 53a may be a rectangle in which two sides in one direction are parallel to the line 511a and at a certain distance from the line 511a, and two sides in the other direction are perpendicular to the line 511a and at a certain distance from the starting point 503a. If the landing point 504 is within region 53a, the determination unit 163 determines that the landing point 504 is included in the region of the pit 50a. Similarly, the acquisition unit 161 acquires the position of the region corresponding to the pit 50b, and the determination unit 163 can set region 53b for the pit 50b.

[0042] In the example shown in Figure 1, since the landing point 504 is included in area 53a, the determination unit 163 determines that the landing point 504 is included in the area of ​​pit 50a. In this case, the distance between the landing point 504 and the starting point 503a becomes the record of the trial in pit 50a.

[0043] [Processing flow of the embodiment] The following flowchart explains the processing flow of the measuring device 10. Figure 3 is a flowchart showing the processing flow for registering the starting point.

[0044] As shown in Figure 3, the output control unit 164 displays the competition selection screen (step S101). The output control unit 164 also accepts the selection of a competition via the competition selection screen (step S102).

[0045] The output control unit 164 can display a screen on the display via the output unit 14. Furthermore, the output control unit 164 can receive user input corresponding to the screen via the input unit 13.

[0046] Figure 4 illustrates the screen transitions on the competition selection screen. As shown in Figure 4, the competition selection screen 211 includes a list of competition events, a "Carry over starting information" button, and a "Settings" button.

[0047] The list of competition events allows you to select any of the events. When the "Inherit Starting Point Information" button is pressed, the registered starting point will be used, and the starting point registration process described later will be skipped. When the "Settings" button is pressed, a settings screen will be displayed. On this settings screen, you can configure the competition events to display, the number of pits for each competition, the method for determining the area, and so on.

[0048] When a competition is selected from the list of competition events, the output control unit 164 displays a pit number selection field. The competition selection screen 212 in Figure 4 displays a pit number selection field where "1 pit" or "2 pits" can be selected.

[0049] Returning to Figure 3, the output control unit 164 accepts input for the number of pits (step S103). For example, if "2 pits" is selected, the output control unit 164 transitions the screen to the starting point registration screen 213. On the starting point registration screen 213, registration of the starting points for "Pit A" and "Pit B" is accepted.

[0050] The output control unit 164 registers the starting point of any pits whose starting points have not yet been registered, in response to the input (step S104). If there are still pits whose starting points have not yet been registered (step S105; Yes), the output control unit 164 returns to step S104 and repeats the registration of the starting points. If there are no more pits whose starting points have not yet been registered (step S105; No), the output control unit 164 terminates the process.

[0051] Figure 5 illustrates the screen transitions on the starting point registration screen. For example, when the "Register Starting Point" button is pressed on the starting point registration screen 213 in Figure 4, the output control unit 164 displays the starting point registration screen 221 in Figure 5. The starting point registration screen 221 accepts registration of the starting point of the first pit (pit A). The registration of the starting point is performed by the measuring device 10 measuring the distance to the prism marker installed by the user.

[0052] If the selected event is the long jump, the measuring device 10 measures the distance to two base points. For this reason, the output control unit 164 displays a message on the starting point registration screen 221 prompting the user to place a prism marker at the first base point (one end of the takeoff board) and operate the "Register" button. The takeoff board is sometimes referred to as the "white board".

[0053] When the "Register" button is pressed on the starting point registration screen 221, the output control unit 164 transitions the screen to the starting point registration screen 222. On the starting point registration screen 222, the output control unit 164 displays a message prompting the user to place a prism marker at the second starting point (one end of the level crossing board) and press the "Register" button.

[0054] Furthermore, when the "Register" button is pressed on the starting point registration screen 222, the output control unit 164 calculates the midpoint coordinate of the two base points as the starting point coordinate. The output control unit 164 also obtains the method for calculating the starting point according to the selected competition from the competition information 151. The output control unit 164 then adds the calculated starting point to the registration information 152. Finally, the output control unit 164 transitions the screen to the starting point registration screen 223 to notify that the starting point registration is complete.

[0055] Figure 5 shows the screen when registering the starting point of "Pit A". The output control unit 164 similarly registers the starting point for "Pit B".

[0056] Figure 6 illustrates the processing of the measuring device 10 after the starting point has been registered and when the trial measurement is actually performed. Figure 6 is a flowchart showing the processing flow for outputting the record. The measuring device 10 automatically determines which of the multiple pit areas the position of the object to be measured (for example, the landing point) is located in.

[0057] The output control unit 164 accepts the designation of one of several pits (step S201). The "Measure A Pit" button and the "Measure B Pit" button on the starting point registration screen 213 in Figure 4 are displayed on the screen after starting point registration. The output control unit 164 accepts the designation of a pit by operating the "Measure A Pit" button and the "Measure B Pit" button.

[0058] The acquisition unit 161 acquires the position of the landing point (step S202). The determination unit 163 determines whether or not the landing point is included in the area associated with the pit (step S203).

[0059] If the calculation unit 162 determines that the landing point is included in the area associated with the pit (step S204; Yes), it calculates the distance between the landing point and the starting point of the designated pit (step S205). Then, the output control unit 164 outputs the calculated distance (step S206). For example, the output control unit 164 displays the calculated distance on the record display screen.

[0060] Figure 7 shows an example of a record display screen. Record display screen 231 shows the record when the designated pit is "Pit A". Record display screen 232 shows the record when the designated pit is "Pit B".

[0061] Thus, if the determination unit 163 determines that the location of the object to be measured is included in the region, the output control unit 164 outputs the distance between the first location and the location of the object to be measured.

[0062] If the output control unit 164 determines that the landing point is not included in the area associated with the pit (step S204; No), it outputs an error message (step S207). For example, the output control unit 164 displays the error message on the error display screen.

[0063] Figure 8 shows an example of an error display screen. The error display screen 241 displays a message indicating that the pit being measured may be incorrect. The error display screen 241 also displays two buttons: "Change pit and measure" and "Continue measuring." If the "Change pit and measure" button is pressed, the output control unit 164 accepts the pit selection again. If the "Continue measuring" button is pressed, the output control unit 164 displays the record display screen.

[0064] Thus, if the determination unit 163 determines that the location of the object to be measured is not included in the region, the output control unit 164 outputs information indicating that the location of the object to be measured is not included in the region.

[0065] Furthermore, the measuring device 10 may automatically detect pits and output records. Figure 9 is a flowchart showing the process flow for detecting pits and acquiring records.

[0066] As shown in Figure 9, the acquisition unit 161 acquires the position of the landing point (step S301). The calculation unit 162 calculates the distance between the landing point and each of the starting points of the multiple pits (step S302).

[0067] The judging unit 163 determines the pit corresponding to the landing point using a judging method determined for each competition (step S303). For example, the judging unit 163 makes the judgment by setting an area of ​​the predetermined shape as described above.

[0068] The output control unit 164 outputs the distance between the landing point and the starting point of the pit corresponding to the landing point (step S304).

[0069] [Other embodiments] The measuring device 10 can be applied to athletic events other than the long jump and triple jump. Figure 10 illustrates an example of when the measuring device 10 is applied to the hammer throw, discus throw, and shot put. Figure 10 is a diagram illustrating the measuring areas for the hammer throw, discus throw, and shot put.

[0070] In throwing events such as hammer throw, discus throw, and shot put, the record is the distance from the starting point to the landing point of the thrown object. The competition venue is equipped with measurement areas 60a and 60b for hammer throw, discus throw, or shot put. These measurement areas correspond to the pits.

[0071] As shown in Figure 10, the measuring device 10 measures the position of the starting point 601a and the position of point 602a inside the white line 63a. The measuring device 10 identifies a straight line 612a obtained by tilting the straight line 611a connecting the starting point 601a and point 602a by 34.92° with the starting point 601a as the center. The area enclosed by the straight lines 611a and 612a, and outside the throwing circle 64a, corresponds to the measurement area 60a. A white line 62a is also drawn on the straight line 612a. For example, the measuring device 10 determines that the landing point 603a is included in the measurement area 60a.

[0072] The measuring device 10 similarly identifies the area for the measurement area 60b. The measuring device 10 measures the position of the starting point 601b and the position of point 602b inside the white line 63b. The measuring device 10 identifies a straight line 612b obtained by tilting the straight line 611b connecting the starting point 601b and point 602b by 34.92° with the starting point 601b as the center. The area enclosed by the straight lines 611b and 612b, and outside the throwing circle 64b, corresponds to the measurement area 60b. A white line 62b is also drawn on the straight line 612b. For example, the measuring device 10 determines that the landing point 603b is included in the measurement area 60b.

[0073] For example, in hammer throw, discus throw, and shot put, the record is calculated by subtracting the radius of the throwing circle from the distance from the starting point to the landing point.

[0074] An example of how the measuring device 10 is applied to javelin throwing will be explained using Figure 11. Figure 11 is a diagram illustrating the measuring area for javelin throwing. The stadium is equipped with measuring area 70a and measuring area 70b for javelin throwing. Note that the measuring area corresponds to the pit.

[0075] The measuring device 10 measures the position of the starting point 701a and the position of point 702a inside the white line 73a. The measuring device 10 identifies a straight line 712a obtained by tilting the straight line 711a connecting the starting point 701a and point 702a by 28.96° with the starting point 701a as the center. The area enclosed by straight lines 711a and 712a corresponds to the measurement area 70a. A white line 72a is also drawn on straight line 712a. For example, the measuring device 10 determines that the landing point 703a is included in the measurement area 70a.

[0076] The measuring device 10 measures the position of the starting point 701b and the position of point 702b inside the white line 73b. The measuring device 10 identifies a straight line 712b obtained by tilting the straight line 711b connecting the starting point 701b and point 702b by 28.96° with the starting point 701b as the center. The area enclosed by the straight lines 711b and 712b corresponds to the measurement area 70b. In addition, a white line 72b is drawn on the straight line 712b. For example, the measuring device 10 determines that the landing point 703b is included in the measurement area 70b.

[0077] [Effects of the Embodiment] The acquisition unit 161 acquires a plurality of locations identified using one optical distance meter, and the location of the object to be measured, which is identified using the optical distance meter and is different from any of the plurality of locations. The calculation unit 162 calculates the distance between at least one of the plurality of locations and the location of the object to be measured.

[0078] This allows the measuring device 10 to measure records from multiple pits with a single unit. As a result, the number of devices installed in the stadium is reduced, and records for track and field events can be acquired more efficiently.

[0079] The determination unit 163 determines whether the location of the measurement target is included in the region corresponding to the first location, based on the distance between the first location and the location of the measurement target. Furthermore, if the determination unit 163 determines that the location of the measurement target is included in the region, the output control unit 164 outputs the distance between the first location and the location of the measurement target. This allows the measuring device 10 to automatically record data corresponding to the pits.

[0080] If the determination unit 163 determines that the location of the object to be measured is not included in the region, the output control unit 164 outputs information indicating that the location of the object to be measured is not included in the region. This prevents the measuring device 10 from recording incorrect data.

[0081] The determination unit 163 determines that the position of the object to be measured is included in the region corresponding to the position with the minimum distance from the object to be measured among multiple positions. As a result, the measuring device 10 can measure the records of multiple pits in the throwing event.

[0082] The determination unit 163 determines whether the position of the object to be measured is included in the region enclosed by a first straight line connecting a first point and a second point, which are indicated at the first position, and a second straight line that forms a predetermined angle with the first straight line and passes through the first point. This allows the measuring device 10 to measure the records of multiple pits in a throwing event.

[0083] The determination unit 163 determines whether the position of the object to be measured is included in the region corresponding to the first position, which is determined according to the specified track and field event. This allows the measuring device 10 to support multiple athletic events and measure records at multiple pits.

[0084] The acquisition unit 161 may acquire the position of the region corresponding to the first position, and the determination unit 163 may determine, based on the acquired position of the region, that the position of the object to be measured is included in the region. This allows the measuring device 10 to automatically record data corresponding to each region (e.g., pit).

[0085] Figure 12 is a diagram showing an example of the hardware configuration of a server according to an embodiment. As shown in Figure 12, the measuring device 10 includes a computer comprising a processor 1010, a memory 1020, an input / output IF 1030, and a bus 1040. The processor 1010, the memory 1020, and the input / output IF 1030 can send and receive information from each other via the bus 1040.

[0086] The processor 1010 performs each function by reading and executing a management program stored in memory 1020. The processor 1010 is, for example, an example of a processing circuit and includes one or more of the following: a CPU, a DSP (Digital Signal Processor), and a system LSI (Large Scale Integration).

[0087] Memory 1020 includes one or more of the following: RAM, ROM, flash memory, EPROM (Erasable Programmable Read Only Memory), and EEPROM (Registered Trademark) (Electrically Erasable Programmable Read Only Memory). Input / Output IF 1030 includes, for example, an AD converter, a DA converter, and an input / output port.

[0088] The measuring device 10 may also be configured to include a data reading unit that reads a management program from a recording medium on which a computer-readable management program is recorded. The processor 1010 can control the data reading unit to obtain the management program recorded on the recording medium from the data reading unit and store the obtained management program in the memory 1020.
