Description

Measuring equipment

Technical Field

The present specification relates to the field of professional measuring instruments, and in particular to a measuring device.

Background

In outdoor sports or finishing measurements, it is often the case that it is necessary to obtain data about the connection between two points. However, the data between these two points is sometimes inconvenient or not directly measurable. For example, in golf, a player may want to obtain the distance and slope angle of the line between two points on the green. However, due to the relief change of the green, an obstacle is often present on the direct connection between the two points, which results in that the data between the two points cannot be directly measured.

In order to obtain target data more flexibly and conveniently and improve the measurement experience of users, it is necessary to provide a measuring device capable of obtaining data between two points other than the measuring device, in particular a measuring device capable of obtaining a distance between two points and a gradient angle.

The content of the background section is only information that is known to the applicant's individual and is not representative of such information as has entered public domain prior to the filing date of this disclosure, nor of the prior art to which this disclosure may be directed.

Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the invention, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the disclosure. Thus, the present description is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the claims.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. For example, as used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. The terms "comprises," "comprising," "includes," and/or "including," when used in this specification, are taken to specify the presence of stated integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

These and other features of the present specification, as well as the operation and function of the related elements of structure, as well as the combination of parts and economies of manufacture, may be significantly improved upon in view of the following description. All of which form a part of this specification, reference is made to the accompanying drawings. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended as a definition of the limits of the description. It should also be understood that the drawings are not drawn to scale.

That is, X may include only any one of A, B, C, or any combination of A, B, C, as well as other possible content/elements. Any combination of the A, B, C may be A, B, C, AB, AC, BC, or ABC.

In the present specification, unless explicitly stated otherwise, the association relationship generated between structures may be a direct association relationship or an indirect association relationship.

And so on.

Before a specific description of the measurement device provided in the present specification, some application scenarios will be introduced.

For example, in finishing measurements, a user needs to measure the distance between two target points on two adjacent walls and the slope angle of the line. However, the two target points are separated by the wall body, and the common measuring equipment cannot meet the measuring requirement. The measuring device provided by the specification can be used for respectively measuring the distance and the inclination angle of the connecting line between the observation point and the two target points in a mode of being rotatably fixed at a certain observation point, so that the target data between the two target points are obtained. In this measurement mode, the two target points are also the measurement points at which we actually measure. Wherein the target data refers to the related data between the first target point and the second target point indirectly obtained based on the measurement data. The target data includes a target distance between two target points and a target gradient angle of a line connecting the two target points. The target gradient angle refers to an included angle between a connecting line of two target points and a horizontal plane.

For example, in bridge construction engineering, a technician needs to measure the distance between the start point and the end point of a bridge on both sides of a river and the gradient angle of the bridge. There is also a great deal of similar measurement requirements in road and railway construction projects. As another example, during golf practice, a golfer needs to acquire as much data as possible to assist himself in making a shot decision. The golf course has variations in height, and particularly as the golf ball approaches or falls into the green area, the terrain becomes more complex and how to obtain accurate data becomes more important to the player. In order to be able to make a more accurate shot decision, the golfer often measures the distance between a certain target point and the distance measuring device by means of the distance measuring device or the slope angle of the line between a certain target point and the slope measuring device by means of the slope angle measuring device. For example, a golfer needs to obtain information on the distance from the striking point to the hole and the slope to help himself determine how to strike the ball.

However, the measurement apparatus in the related art can obtain data between the measurement apparatus and the measurement point, but cannot accurately acquire data between two target points other than the measurement apparatus. For illustrative purposes only, the present description will describe the summary of the invention by taking a golf ball measurement device as an example. Those skilled in the art will appreciate that the same techniques may be applied to other applications without departing from the core spirit of the invention.

Fig. 1 illustrates an application scenario diagram of a measurement device provided according to some embodiments of the present description. The first measurement point a may be a point on the golf ball 003 or a point near the striking point that is convenient for measurement, and the second measurement point B may be a point at the edge of the hole 004 or a point within the range of the hole 004 that can be observed by the user of the device 001. For example, the second measurement point may be a pin 005 inserted into the center of the hole 004 to mark the position of the hole 004. The lawn area where the hole 004 is located is called green 002. Generally, the terrain of the green 002 is complex and various, and has a fluctuation. The closed curves of the loops shown in fig. 1 are contours with the centermost hole 004 being the highest point and progressively lower in altitude downward. Fig. 1 does not limit the shape of the green 002. The golfer needs to know the topography fully through observation or measurement to properly plan the ball path. When the golf ball 003 falls on the edge of the green 002 or has entered the green 002, data information such as the distance between the golf ball 003 and the hole 004, the gradient angle, etc. are of great value for guiding the golfer's putting. For another example, the user may select any two points on the ball as target points when planning the route for the ball stroke to analyze the feasibility of the route based on the target data. The first target point in one measurement may be the first target point or the second target point in another measurement; the second target point in one measurement may also be the first target point or the second target point in another measurement; or there are no identical target points in the multiple measurements. For the same two target points, measurement can be performed at different observation points, or different measurement points or measurement modes can be selected for measurement.

The observation point is the position where the measurement device is located. The measurement device may be abstracted to a point within an acceptable error range with respect to the magnitude of the target data. The measurement point is a point at which measurement data is directly acquired by the measurement device, and the direct acquisition can be acquired through measurement or by reading preset or user input data. The measurement point may be the same point as the target point, may be a different point from the target point, or may have a part thereof as the target point. The user uses the measuring device to obtain actual measurement data between the observation point and the measurement point.

Fig. 2 shows a block schematic of a measurement device provided according to some embodiments of the present description. The measurement device 001 may include a measurement assembly 100, a storage medium 200, and a processor 300. The measuring assembly 100 can be operated to measure the distance between two points, to measure the inclination of a line between two points, and to measure the angle between two lines in a plane. The storage medium 200 may store data information including the above-described measurement data as a data storage medium. The storage medium 200 may also store at least one set of instructions as an instruction memory. The number of storage media 200 may be one or more, and the data and instruction sets may be stored on one storage medium 200 or on a different storage medium 200. The processor 130 is communicatively coupled to the at least one storage medium 200 and the measurement assembly 100 such that the processor 130, when executed, can execute at least one set of instructions in the storage medium 200 to obtain target data based on measurement data output by the measurement assembly 100. The data of the processor may be one or more.

To obtain the distance between the observation point and the measurement point, the measurement assembly 100 may include a distance measurement module 110. The distance measuring module can be implemented in various ways. For example, the distance measuring module 110 may be an ultrasonic ranging module. The ultrasonic ranging module emits ultrasonic outwards during operation, records the time interval from the time of emission to the time of receiving the ultrasonic after being reflected by the measuring point, and combines the propagation speed of the ultrasonic to obtain the distance of the measuring point. The ultrasonic ranging module may include a signal processor, an ultrasonic transmitter, and an ultrasonic receiver. In order to obtain the ambient temperature during the operation of the ultrasonic ranging module so as to obtain a more accurate ultrasonic propagation speed, the ultrasonic ranging module can also comprise a temperature sensor. For another example, the distance measuring module 110 may be a laser ranging module. When the laser ranging module operates, one or more wavelengths of lasers can be emitted and received outwards, and the distance is calculated based on a triangle method, a flight method, a phase method or an interference ranging method and the like.

To obtain the inclination of the line between the observation point and the measurement point with respect to the reference coordinate, the measurement assembly 100 may include an angle sensing module 120. The angle sensing module 120 may be used to measure the inclination angle between the observation point and the measurement point. The inclination angle with respect to the reference coordinate may be an inclination angle with respect to the gravity direction or an inclination angle with respect to the horizontal direction. For this purpose, the angle sensor module 120 may be an inclination measuring device. The angle sensor module 120 can also be used for measuring the included angle between the observation point and the connecting line between two measurement points. For this purpose, the angle sensor module 120 may be an electronic gyroscope, a mechanical angle measuring instrument, or a combination of an inclination measuring device and an electronic compass.

Fig. 3 shows a schematic view of an angle measurement of the measuring device 001. The angle sensor module 120 can obtain the angle vector of the measuring device 001 relative to the reference coordinate systemThe reference coordinate system is an angle coordinate system taking O as a circle center,Wherein, beta' is the angle vector/>The projection on the XOY plane forms an included angle with the X axis; beta' is the included angle between the projection of the angle vector on the YOZ plane and the Y axis; beta' "is the angle vector/>The projection onto the XOZ plane is at an angle to the Z axis.

The storage medium 200 may include a data storage device. The data storage device may store therein measurement data. The data storage device may be a non-transitory storage medium or a transitory storage medium. For example, the data storage device may include one or more of a magnetic disk, a Read Only Memory (ROM), or a Random Access Memory (RAM). The storage medium 200 also includes at least one set of instructions stored in a data storage device. The instruction set is computer program code, which may include programs, routines, objects, components, data structures, procedures, modules, etc. that obtain target data between two target points.

The processor 300 may execute at least one set of instructions in the storage medium to cause the device to: measurement data between the observation point and the first and second measurement points output by the measurement assembly 100 is obtained, and target data is obtained based at least on the measurement data. The target data comprises a target distance between the first target point and the second target point and a target gradient angle, and the target gradient angle is an included angle between a connecting line between the two target points and a horizontal plane. The processor may be in the form of one or more processors. The processor may issue execution instructions. A processor may include one or more hardware processors, such as microcontrollers, microprocessors, reduced Instruction Set Computers (RISC), application Specific Integrated Circuits (ASIC), application specific instruction set processors (ASIP), central Processing Units (CPU), graphics Processing Units (GPU), physical Processing Units (PPU), microcontroller units, digital Signal Processors (DSP), field Programmable Gate Arrays (FPGA), advanced RISC Machines (ARM), programmable Logic Devices (PLD), any circuit or processor capable of executing one or more functions, or the like, or any combination thereof.

To be able to aim at the measurement point more accurately, in some embodiments the measurement device may also comprise a telescopic system. The telescopic system can use part or all of the optical structure of the laser ranging module. The telescopic system may also include an eyepiece for viewing by the user. The user can accurately locate the measurement point within the field of view through the telescopic system.

Fig. 4 shows a schematic diagram of a laser ranging module structure of the measuring device 001. The telescopic system uses the optical structure of the laser ranging module. The laser ranging module includes: a laser light emitting unit 111, an emitting lens 112, an objective lens 113, a prism group 114, and a laser light receiving unit 117. A laser light emitting unit 111 that emits laser light in operation. In some embodiments, the lasing light is a visible laser light. In some embodiments, the lasing light is invisible light. In some embodiments, the laser light may be continuously emitted outward. In some embodiments, the laser light is emitted in a pulsed manner. The emission lens 112 may collimate the emission laser light such that the laser light passes through the emission lens 112 to the measurement point. The objective lens 113 may receive the first reflected laser light of the ranging laser light reflected by the measuring point, and may also receive the visible light. The prism group 114 includes at least one prism for performing optical path deflection on the first reflected laser light and the visible light so that the first reflected laser light reaches the laser receiving unit after being deflected, and the visible light reaches the eyes of the user after being deflected. The laser light receiving unit 117 operates in response to the first reflected laser light. The structure can realize laser receiving and transmitting telescope, and a user can use the laser ranging function of the measuring equipment 001 when using the telescope system to accurately position a measuring point.

In some embodiments, the distance measurement module includes two laser transmitters that can transmit laser light at two wavelengths to achieve a first measurement mode and a second measurement mode. In the first ranging mode, the laser emitting unit 111 emits first laser light of a first wavelength, and the measuring apparatus 001 measures distance data between the observation point and the measurement point with a measurement error of 10 cm or less. In the second ranging mode, the laser emission unit 111 emits a second laser light of a second wavelength, and the measurement device 001 measures distance data between the observation point and the measurement point with a measurement error of 1 meter or less. The measuring device 001 may determine whether to automatically switch to another measuring mode based on the distance data measured in one of the measuring modes. For example, when the distance between the observation point and the measurement point is 20 meters by using the second measurement mode, the measurement device determines that the measurement error of 1 meter satisfies the preset switching condition for the distance data of 20 meters, and automatically switches to the first measurement mode for measurement.

In order to automatically acquire the height data of the observation point, the distance measurement module can also design a group of downward distance measurement light paths through the composite use of the light paths. Fig. 5 shows a schematic diagram of a laser ranging module structure of a measuring device 001 with a structure that can range downward. The laser ranging module shown in fig. 5 is improved on the basis of it compared to fig. 4. Specifically, the laser ranging module further includes a first mirror 118. While the measurement device 001 is kept level, the first mirror 118 may reflect at least part of the laser light for measuring a first distance of the measurement device 001 to the first measurement point a. At the same time, the first mirror 118 allows at least part of the laser light to pass through in order to measure the second measuring point B. The laser ranging module further includes a second mirror 119. When the measuring device 001 is kept horizontal, the second mirror 119 reflects the second reflected laser light reflected by the first measuring point a. The prism group 114 also deflects the second reflected laser beam so that the second reflected laser beam reaches the laser receiving unit after being deflected. The laser light receiving unit 117 operates in response to the first reflected laser light and the second reflected laser light. The measurement device 001 discriminates the first reflected laser light and the second reflected laser light from each other according to the time when they reach the laser light receiving unit 117.

The various measuring modes of the measuring device will be described below in connection with some of the use modes. One or more measurement modes may be present in one measurement device 001.

Fig. 6 illustrates a schematic diagram of the use of a measurement device 001 provided in accordance with some embodiments of the present description. The observation point O is the position where the measurement device 001 is located when the user stands at the first target point to hold the measurement device 001 for measurement. The first measurement point A is the position of the first target point. For example, the first measurement point and the first target point are ball striking points. In order to obtain the first distance in the first measurement data between the observation point O and the first measurement point a, the measurement device 001 measures the first distance d ₁, or obtains a user input or preset first distance d ₁. In some embodiments, the user holds the measurement device 001, adjusts the measurement direction to a vertically downward direction, and takes the measurement. In some embodiments, the first distance d ₁ is obtained by a laser ranging module as shown in fig. 4. Specifically, the user can hold the measurement device 001 to aim the objective lens 113 of the measurement module at his foot to measure the first distance d ₁; in some embodiments, the user may also obtain the first distance d ₁ by measuring through an auxiliary ranging unit of the distance measurement module. When the measuring device 001 is kept horizontal, the auxiliary ranging unit may emit a vertically downward laser or ultrasonic wave to measure the first distance d ₁ while operating. Or in some embodiments, the first distance d ₁ is stored as a default parameter in the measurement device 001. In some embodiments, the user may input or modify the first distance d ₁ into the measurement device 001 with reference to his or her actual height data. One possible way of referencing the height data is to use the height data minus 10 cm (head-to-eye distance) as the first distance d ₁. In order to obtain the first inclination angle in the first measurement data between the observation point O and the first measurement point a, the measurement apparatus 001 automatically sets the first inclination angle of the connection line OA of the observation point O and the first measurement point a with respect to the gravitational direction to be 0 °.

The second measurement point B is the position of the second target point. For example, the second measurement point and the second target point are holes. In order to obtain second measurement data between the observation point O and the second measurement point B, the measurement apparatus 001 measures a second distance d ₂ and a second inclination angle θ ₂ of a connection OB of the observation point O and the second measurement point B with respect to the gravitational direction. For example, the second inclination angle θ ₂ is an inclination angle of the measurement device 001 measured by the angle sensing module 120 relative to the gravitational direction when the objective lens 113 is aligned with the second measurement point B.

The processor 300 of the measuring device 001 determines target data between the first target point and the second target point based on the first measurement data d ₁ and the second measurement data d ₂、θ₂ output by the measuring assembly 100. The first distance d ₁ and the second distance d ₂ are obtained by a distance measuring module of the measuring device 001, and the second inclination angle θ ₂ is obtained by an angle sensing module. After the processor 300 of the measuring apparatus 001 receives the above-mentioned measurement data acquired by the distance measuring module 110 and the angle sensing module 120, the target distance and the target gradient angle in the target data are determined by triangulation. The calculation method is as follows:

The observation point O is the position where the measurement device 001 is located when the user performs measurement. In this measurement mode, the observation point O is located neither above the first target point nor above the second target point.

The first measurement point A is the position of the first target point. For example, the first measurement point and the first target point are ball striking points. In order to obtain the first measurement data, the measurement device 001 measures a first distance d ₁ between the observation point O and the first measurement point a and a first inclination angle θ ₁ of the first connection line OA with respect to the gravity direction, the first connection line OA being a connection line between the observation point O and the first measurement point a.

The processor of the measuring device 001 determines target data between the first target point and the second target point based on the first measurement data d ₁、θ₁ and the second measurement data d ₂、θ₂ output by the measuring component. The first distance d ₁ and the second distance d ₂ are obtained by a distance measuring module of the measuring device 001, and the first inclination angle θ ₁, the second inclination angle θ ₂, and the included angle β between the first connection OA and the second connection OB are obtained by an angle sensing module. After receiving the above measurement data acquired by the distance measurement module and the angle sensing module, the processor of the measurement device 001 determines the target distance and the target gradient angle in the target data by a triangulation method. The calculation method is as follows:

The target gradient angle alpha is an included angle of a connecting line of the first target point and the second target point relative to a reference plane by taking the horizontal plane of the first target point as the reference plane. When the calculation result of alpha is positive, the second target point is higher than the first target point; when the calculation result of alpha is negative, the second target point is lower than the first target point; and when the calculation result of alpha is zero, the second target point is equal to the first target point in height.

In an application scenario of golf sport, a user may take golf ball 003 as a first target point, hole 004 as a second target point, and obtain a target distance L and a target slope angle α between the ball and hole 004 using measurement device 001. The user stands away from the golf ball 003 during the measurement. The position of the measuring device 001, or the position of the eyepiece of the measuring device 001, is the position of the observation point. The user observes the position of the golf ball 003 through the telescopic system of the measuring device 001 to determine the first measuring point a to be measured. The first measurement point a may be a certain point on the golf ball 003, and the user observes the position of the golf ball 003 through the telescopic system to determine the first measurement point a to be measured. The measurement device 001 acquires first measurement data between it and the first measurement point a. The first measurement data includes a first distance d ₁ between the observation point and the first measurement point a and a first tilt angle θ ₁.

In addition, the measuring device 001 also obtains the angle through which the device rotates during the process of measuring from the first measuring point A to the second measuring point B. I.e. the angle between the first line of observation points and the first measurement point a and the second line of observation points and the second measurement point B. In this measurement mode, the first measurement point a coincides with the first target point and the second measurement point B coincides with the second target point.

Fig. 8 illustrates a schematic diagram of the use of a measurement device 001 provided in accordance with some embodiments of the present description. The observation point O is the position where the measurement device 001 is located when the user stands at the first target point to hold the measurement device 001 for measurement.

In order to obtain the first distance in the first measurement data between the observation point O and the first measurement point a, the measurement device 001 measures the first distance d ₁, or obtains a user input or preset first distance d ₁. In some embodiments, the user holds the measurement device 001, adjusts the measurement direction to a vertically downward direction to take the measurement (i.e., maneuvers the objective lens 113 toward the ground). In some embodiments, the user may also obtain the first distance d ₁ through a laser ranging module as shown in fig. 4. For example, the user may measure the first distance d ₁ through the auxiliary ranging unit of the distance measuring module. When the measuring device 001 is kept horizontal, the auxiliary ranging unit may emit a vertically downward laser or ultrasonic wave to measure the first distance d ₁ while operating. In some embodiments, the first distance d ₁ is stored as a default parameter in the measurement device 001. In some embodiments, the user may input or modify the first distance d ₁ into the measurement device 001 with reference to his or her actual height data. One possible way of referencing the height data is to use the height data minus 10 cm (the head-to-eye distance) as the first distance d ₁. In order to obtain the first inclination angle in the first measurement data between the observation point O and the first measurement point a, the measurement apparatus 001 automatically sets the first inclination angle of the connection line OA of the observation point O and the first measurement point a with respect to the gravitational direction to be 0 °.

The second measurement point B is a point on the reference object standing above the second target point. For example, the second measurement point B may be a point on a flagpole above the hole. The distance between the second measuring point B and the ground is a third distance d ₃. In order to obtain the second measurement data, the measurement device 001 measures a second distance d ₂ between the observation point O and the second measurement point B and a second inclination angle θ ₂ of the connection line OB thereof with respect to the gravitational direction. Specifically, the user can hold the measuring device 001 to aim the objective lens 113 of the measuring module at the second measuring point B for measurement. The distance measuring module 110 in the measuring device 001 may obtain the second distance d ₂, and the angle sensing module 120 may obtain the second inclination angle θ ₂ of the measuring device 001 with respect to the gravity direction.

The processor of the measuring device 001 determines target data between the first target point and the second target point based on the first measurement data d ₁, the second measurement data d ₂、θ₂, and the third distance d ₃ output by the measuring component. The first distance d ₁, the second distance d ₂, and the third distance d ₃ are obtained by the distance measuring module 110 of the measuring device 001, and the first inclination angle θ ₁ and the second inclination angle θ ₂ are obtained by the angle sensing module 120. After receiving the measurement data obtained by the distance measurement module and the angle sensing module, the processor of the measurement device 001 obtains the target distance and the target gradient angle in the target data by a quadrilateral measurement method. In the case where the third distance d ₃ is approximately equal to the first distance d ₁, the approximate calculation of the target distance L is as follows:

Target distance l=d ₂

Target gradient angle α=θ ₂ -90°

The target gradient angle alpha is an included angle of a connecting line of the first target point and the second target point relative to a reference plane by taking the horizontal plane of the first target point as the reference plane. When the calculation result of alpha is positive, the second target point is higher than the first target point; when the calculation result of alpha is negative, the second target point is lower than the first target point; and when the calculation result of alpha is zero, the second target point is equal to the first target point in height.

In the application scenario of golf, the user may take golf ball 003 as the first target point while selecting the first target point as the first measurement point a. The user may take the hole 004 as the second target point and select a particular point above the hole 004 as the second measurement point B. The user stands beside golf ball 003 during the measurement. The position of the measuring device 001 is the position of the observation point. Based on the measurement data between the observation point and the first measurement point a and the second measurement point B, a target distance L and a target gradient angle α between the ball and the hole 004 are obtained. The distance between the observation point and the first measurement point a is a first distance d ₁. The first distance d ₁ is substantially equivalent to the distance of the user's eyes to the ground.

The user observes the point on the flagpole through the telescopic system of the measuring device 001, determining the second measuring point B to be measured. The second measurement point B is a point on the flag pole. The distance between the second measurement point B and the hole 004 is the third distance d ₃. The measurement device 001 acquires second measurement data between the observation point and the second measurement point B. The second measurement data includes a third distance d ₃ between the observation point and the second measurement point B. In this measurement mode, the first measurement point a coincides with the first target point and the second measurement point B is above the second target point.

In some embodiments, the user uses a visual observation to determine the third measurement point on the flag pole. The principle of determination is to make the second height equal to the first height as much as possible. That is, a point on the flagpole is measured that is as close as the user's height (in practice, the distance of the human eye from the ground).

Of course, it is not possible for the human eye to be positioned exactly to the third measuring point equal to the first height in each measurement. The smaller the difference between the second height and the first height, the smaller the error in estimating the distance between the first target point and the second target point using the distance between the observation point and the third measurement point. The height of the third measuring point can be estimated more accurately when the user is closer to the flagpole. Although this time there is a higher requirement for accuracy, the overall result is also satisfactory since the estimate for the second height is more accurate. Similarly, when the user is farther from the flag pole, the accuracy requirement for distance becomes lower, although the estimate for the second height is less accurate, the result is acceptable for lower accuracy requirements.

In summary, the measuring device 001 provided in the present specification can obtain the target distance and the target gradient angle between the two target points through different measurement modes. One or more measurement modes may be present in one measurement device 001.

When the target distance is the distance between the golf ball 003 and the hole 004 and the target distance is 50 meters or less, the ball 003 is in a state of being close to the green 002 or being above the green 002. At this time, the ball striking advice obtained based on the target data has guiding significance for the subsequent operations of the player.

The environmental data includes one or more of wind speed data, wind direction data, or temperature data. The measuring device 001 outputs the ball striking advice based on the environmental data and the target data of the measuring device. For example, when the wind direction data indicates that the moment is against the wind, the recommended value for the striking power in the striking recommendation is larger than that in the case of no wind. When the wind direction data indicates that the moment is downwind, the recommended value for the striking force in the striking recommendation is smaller than that in the windless case.

In some embodiments, the measurement device 001 may also output a shot proposal. For example, the measurement device 001 may display one or more of the shot proposals via a display.
