Description

A measuring device Technical Field

[0001] This specification relates to the field of professional measuring instruments, and in particular to a measuring device. Background Art

[0002] During outdoor activities or renovations, obtaining data related to the line connecting two points is often necessary. However, this data is sometimes inconvenient or impossible to measure directly. For example, in golf, a golfer may want to determine the distance and slope angle between two points on a green. However, due to the uneven terrain of the green, obstacles often exist along the line connecting the two points, making it impossible to directly measure the data between the two points.

[0003] In order to obtain target data more flexibly and conveniently and improve the user's measurement experience, it is necessary to provide a measuring device that can obtain data between two points in addition to the measuring device, especially a measuring device that can obtain the distance and slope angle between the two points.

[0004] The content of the background technology section is merely information known to the applicant personally, and does not mean that the above information has entered the public domain before the application date of this disclosure, nor does it mean that it can become the prior art of the present disclosure.

[0034] The following description provides specific application scenarios and requirements for this specification, with the goal of enabling those skilled in the art to make and use the contents of this specification. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but is intended to be accorded the broadest scope consistent with the claims.

[0035] The terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. For example, as used herein, the singular forms "a," "an," and "the" may also include the plural forms unless the context clearly indicates otherwise. When used in this specification, the terms "comprise," "include," and / or "contain" are intended to refer to the presence of the associated integers, steps, operations, elements, and / or components, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups or the addition of other features, integers, steps, operations, elements, components, and / or groups in the system / method.

[0036] These and other features of this specification, as well as the operation and function of the associated elements of the structure, and the economical assembly and manufacture of the components, can be significantly improved with consideration of the following description. Reference is made to the accompanying drawings, all of which form a part of this specification. However, it should be expressly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0037] The flowcharts used in this specification illustrate operations implemented by systems according to some embodiments of the present specification. It should be clearly understood that the operations of the flowcharts may not be implemented in sequence. Rather, the operations may be implemented in reverse order or simultaneously. Furthermore, one or more additional operations may be added to the flowcharts. One or more operations may be removed from the flowcharts.

[0038] In this specification, the expression "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. In other words, X may include only any one of A, B, and C, or any combination of A, B, and C, as well as other possible contents / elements. Any combination of A, B, and C may be A, B, C, AB, AC, BC, or ABC.

[0039] In this specification, unless otherwise specified, the association relationship between structures can be a direct association relationship or an indirect association relationship. For example, when describing "A is connected to B", unless it is clearly stated that A is directly connected to B, it should be understood that A can be directly connected to B or indirectly connected to B; for another example, when describing "A is above B", unless it is clearly stated that A is directly above B (AB are adjacent and A is above B), it should be understood that A can be directly above B or indirectly above B (AB is separated by other elements and A is above B). And so on.

[0040] Before describing the measurement equipment provided in this manual in detail, some application scenarios are introduced.

[0041] For example, in decoration measurement, the user needs to measure the distance between two target points on two adjacent walls and the slope angle of the connecting line. However, the two target points are blocked by a wall, and general measuring equipment cannot meet this measurement requirement. The measuring equipment provided in this specification can be rotatably fixed to a certain observation point to measure the distance and inclination of the line between the observation point and the two target points, and then obtain the target data between the two target points. In this measurement method, the two target points are also the measurement points where we actually measure. Among them, the target data refers to the relevant data between the first target point and the second target point indirectly obtained based on the measurement data. The target data includes the target distance between the two target points and the target slope angle of the line connecting the two target points. The target slope angle refers to the angle between the line connecting the two target points and the horizontal plane.

[0042] For example, during bridge construction, technicians need to measure the distance between the starting and ending points of a bridge on either side of a river, as well as the slope angle of the bridge. Similar measurement needs also exist in highway and railway construction projects. Another example is golf, where players need to obtain as much data as possible to help them make informed decisions about their shots. Golf courses are characterized by uneven terrain, and the terrain becomes even more complex as the golf ball approaches or lands on the green. Obtaining accurate data becomes even more crucial for golfers. To make more accurate shots, golfers often use distance measuring devices to measure the distance between a target point and the device, or use slope angle measuring devices to measure the slope angle of the line connecting the target point and the device. For example, golfers need to obtain information about the distance from the shot point to the hole, as well as the slope, to help them determine their shot decisions.

[0043] However, measurement devices in related art can obtain data between the measurement device and a measurement point, but cannot accurately obtain data between two target points other than the measurement device. For illustrative purposes only, this specification will describe the invention using a golf ball measurement device as an example. Those skilled in the art will appreciate that the same technology can be applied to other situations without departing from the core spirit of the invention.

[0044] FIG1 shows a schematic diagram of an application scenario of a measuring device provided according to some embodiments of the present specification. The first measuring point A can be a point on the golf ball 003 or a point near the hitting point that is convenient for measurement, and the second measuring point B can be a point on 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 measuring point can be a flagpole 005 inserted in the center of the hole 004, which is used to mark the position of the hole 004. The lawn area where the hole 004 is located is called the green 002. Generally speaking, the terrain of the green 002 is complex and varied, with ups and downs. The closed curves of the multiple rings shown in FIG1 are contour lines, with the hole 004 in the center as the highest point, and the altitude gradually decreases downwards. FIG1 does not limit the shape of the green 002. Golfers need to fully understand the terrain through observation or measurement in order to reasonably plan their golf courses. When golf ball 003 lands on the edge of green 002 or has already entered green 002, data such as the distance between golf ball 003 and hole 004 and the slope angle is of great value in guiding the golfer's putting. For example, when planning a shot route, the user can select any two points on the route as target points to analyze the feasibility of the route based on the target data. The first target point in one measurement can be the first or second target point in another measurement; the second target point in one measurement can also be the first or second target point in another measurement; or there can be no identical target points in multiple measurements. The same two target points can be measured at different observation points, or different measurement points or measurement methods can be used.

[0045] It should be noted that the observation point refers to the location of the measuring device. If the dimensions of the measuring device are within an acceptable error range relative to the magnitude of the target data, the measuring device can be abstracted as a point. A measurement point is a point where measurement data is directly acquired by the measuring device. This direct acquisition can be achieved through measurement or by reading preset or user-entered data. The measurement point can be the same as the target point, a different point, or a portion of the target point. The user uses the measuring device to acquire the actual measurement data between the observation point and the measurement point.

[0046] FIG2 shows a schematic diagram of a module of a measuring device provided according to some embodiments of the present specification. The measuring device 001 includes a measuring component 100, a storage medium 200, and a processor 300. When the measuring component 100 is in operation, it can measure the distance between two points, the inclination of a line connecting two points, and the angle between two lines in a plane. The storage medium 200 can serve as a data storage medium to store data information including the above-mentioned measurement data. The storage medium 200 can also serve as an instruction memory to store at least one set of instruction sets. The number of storage media 200 is one or more, and the data and instruction sets are stored on one storage medium 200 or on different storage media 200. The processor 130 is communicatively connected to at least one storage medium 200 and the measuring component 100, so that the processor 130 executes at least one set of instruction sets in the storage medium 200 when in operation, thereby obtaining target data based on the measurement data output by the measuring component 100. The data of the processor is one or more.

[0047] In order to obtain the distance between the observation point and the measurement point, the measurement component 100 includes a distance measurement module 110. There are various implementation methods for the distance measurement module. For example, the distance measurement module 110 can be an ultrasonic ranging module. When in operation, the ultrasonic ranging module emits ultrasonic waves and records the time interval from the time the ultrasonic waves are emitted to the time they are received after being reflected by the measurement point. The distance to the measurement point is then calculated based on the propagation speed of the ultrasonic waves. The ultrasonic ranging module can 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 and obtain a more accurate ultrasonic propagation speed, the ultrasonic ranging module can also include a temperature sensor. For another example, the distance measurement module 110 can be a laser ranging module. When in operation, the laser ranging module can emit and receive lasers of one or more wavelengths and calculate the distance based on methods such as triangulation, flight method, phase method, or interferometric ranging.

[0048] In order to obtain the inclination of the line between the observation point and the measurement point relative to the reference coordinate, the measurement component 100 includes an angle sensing module 120. The angle sensing module 120 can be used to measure the inclination between the observation point and the measurement point. The inclination relative to the reference coordinate can be the inclination relative to the direction of gravity or the inclination relative to the horizontal direction. For this purpose, the angle sensing module 120 can be an inclination measuring device. The angle sensing module 120 can also be used to measure the angle between the observation point and the line between the two measurement points. For this purpose, the angle sensing module 120 can be an electronic gyroscope, a mechanical angle measuring instrument, or a combination of an inclination measuring device and an electronic compass.

[0049] Figure 3 shows a schematic diagram of an angle measurement method of the measuring device 001. The angle sensing module 120 can obtain the angle vector of the measuring device 001 relative to the reference coordinate system. The reference coordinate system is an angular coordinate system with O as the center. Where β′ is the angle vector The angle between the projection on the XOY plane and the X axis; β″ is the angle vector The angle between the projection on the YOZ plane and the Y axis; β″′ is the angle vector The angle between the projection on the XOZ plane and the Z axis. When it is necessary to measure the angle in the plane, the measuring device 001 is oriented towards the first measuring point, and the angle sensing module 120 of the measuring device 001 can obtain the first angle vector of the measuring device 001 relative to the reference coordinate system. When the measuring device 001 is rotated to align with the second measuring point, the angle sensing module 120 of the measuring device 001 can obtain the second angle vector of the measuring device 001 relative to the reference coordinate system. Then calculate the first vector and the second vector The angle is

[0050] The storage medium 200 includes a data storage device. The data storage device can store measurement data. The data storage device can be a non-transitory storage medium or a temporary storage medium. For example, the data storage device can include one or more of a disk, a read-only storage medium (ROM), or a random access storage medium (RAM). The storage medium 200 also includes at least one instruction set stored in the data storage device. The instruction set is computer program code, and the computer program code can include a program, routine, object, component, data structure, process, module, etc. for obtaining target data between two target points.

[0051] The processor 300 executes at least one set of instructions stored in the storage medium to cause the device to: obtain measurement data between the observation point output by the measurement component 100 and the first and second measurement points, and obtain target data based at least on the measurement data. The target data includes a target distance and a target slope angle between the first and second target points, wherein the target slope angle is the angle between a line connecting the two target points and a horizontal plane. The processor can be in the form of one or more processors. The processor can issue execution instructions. The processor can include one or more hardware processors, such as a microcontroller, a microprocessor, a reduced instruction set computer (RISC), an application-specific integrated circuit (ASIC), an application-specific instruction set processor (ASIP), a central processing unit (CPU), a graphics processing unit (GPU), a physical processing unit (PPU), a microcontroller unit, a digital signal processor (DSP), a field programmable gate array (FPGA), an advanced RISC machine (ARM), a programmable logic device (PLD), any circuit or processor capable of performing one or more functions, or any combination thereof.

[0052] To more accurately locate the measurement point, in some embodiments, the measurement device may further include a telescopic system. The telescopic system may utilize part or all of the optical structure of the laser rangefinder module. The telescopic system may also include an eyepiece for user observation. The user can use the telescopic system to accurately locate the measurement point within the field of view.

[0053] Figure 4 shows a schematic diagram of the structure of a laser ranging module in the measuring device 001. The telescopic system utilizes the optical structure of the laser ranging module. The laser ranging module includes a laser emitting unit 111, a transmitting lens 112, an objective lens 113, a prism assembly 114, and a laser receiving unit 117. The laser emitting unit 111 emits laser light during operation. In some embodiments, the emitted laser light is visible laser light. In some embodiments, the emitted laser light is invisible light. In some embodiments, the laser light can be emitted continuously. In some embodiments, the laser light is emitted in pulses. The transmitting lens 112 can collimate the emitted laser light, allowing the laser light to pass through the transmitting lens 112 and reach the measurement point. The objective lens 113 can receive the first reflected laser light reflected from the measurement point, and can also receive visible light. The prism assembly 114 includes at least one prism for deflecting the optical paths of the first reflected laser light and the visible light, so that the first reflected laser light reaches the laser receiving unit after deflection, and the visible light reaches the user's eyes after deflection. The laser receiving unit 117 responds to the first reflected laser light during operation. This structure can realize the co-telescopic transmission and reception of lasers. Users can use the telescopic system to accurately locate the measurement point while using the laser ranging function of the measurement device 001.

[0054] In some embodiments, the distance measurement module includes two laser emitters that can emit lasers of two wavelengths, thereby realizing a first measurement mode and a second measurement mode. In the first ranging mode, the laser emitting unit 111 emits a first laser of a first wavelength, and the measuring device 001 measures the distance data between the observation point and the measurement point, and the measurement error is less than or equal to 10 centimeters. In the second ranging mode, the laser emitting unit 111 emits a second laser of a second wavelength, and the measuring device 001 measures the distance data between the observation point and the measurement point, and the measurement error is less than or equal to 1 meter. The measuring device 001 can determine whether to automatically switch to another measurement mode based on the distance data measured in one of the measurement modes. For example, when the distance between the observation point and the measurement point is measured to be 20 meters using the second measurement mode, the measuring device determines that for the distance data of 20 meters, the measurement error of 1 meter meets the preset switching condition, and automatically switches to the first measurement mode for measurement.

[0055] To automatically acquire the height data of the observation point, the distance measurement module can also utilize a combination of optical paths to design a downward distance measurement optical path. Figure 5 shows a schematic diagram of the laser distance measurement module structure of a measuring device 001, which includes a structure capable of downward distance measurement. Compared to Figure 4, the laser distance measurement module shown in Figure 5 is improved upon. Specifically, the laser distance measurement module further includes a first reflector 118. When the measuring device 001 is level, the first reflector 118 can reflect at least a portion of the laser light for measuring the first distance from the measuring device 001 to the first measurement point A. At the same time, the first reflector 118 allows at least a portion of the laser light to pass through for measuring the second measurement point B. The laser distance measurement module also includes a second reflector 119. When the measuring device 001 is level, the second reflector 119 reflects a second reflected laser light reflected from the first measurement point A. The prism assembly 114 also deflects the optical path of the second reflected laser light, allowing it to reach the laser receiving unit after deflection. The laser receiving unit 117 responds to both the first and second reflected laser light during operation. The measuring device 001 distinguishes the first reflected laser light from the second reflected laser light based on the time when the two arrive at the laser receiving unit 117 .

[0056] The following will introduce various measurement modes of the measurement device in combination with some usage modes. A measurement device 001 has one or more measurement modes.

[0057] Figure 6 illustrates a schematic diagram of the use of a measuring device 001 according to some embodiments of this specification. Observation point O is the location of measuring device 001 when a user stands at a first target point and holds measuring device 001 for measurement. First measuring point A is the location of the first target point. For example, the first measuring point and the first target point are the hitting points. To obtain the first distance in the first measurement data between observation point O and first measuring point A, measuring device 001 measures first distance d1, or obtains first distance d1 input by the user or preset by the user. In some embodiments, the user holds measuring device 001 and adjusts the measurement direction to a vertically downward direction for measurement. In some embodiments, first distance d1 is obtained using a laser ranging module as shown in Figure 4. Specifically, the user can hold measuring device 001 and aim the objective lens 113 of the measuring module at their feet to measure first distance d1. In some embodiments, the user can also use the auxiliary ranging unit of the distance measurement module to measure first distance d1. When measuring device 001 is held horizontally, the auxiliary ranging unit can emit a vertically downward laser or ultrasonic wave to measure first distance d1. Alternatively, in some embodiments, the first distance d1 is stored as a default parameter in the measuring device 001. In some embodiments, the user can input or modify the first distance d1 into the measuring device 001 by referring to their actual height data. One possible method of referring to the height data is to use the height data minus 10 centimeters (the distance from the top of the head to the eyes) as the first distance d1. To obtain the first inclination angle in the first measurement data between the observation point O and the first measurement point A, the measuring device 001 automatically sets the first inclination angle of the line OA connecting the observation point O and the first measurement point A relative to the direction of gravity to 0°.

[0058] The second measurement point B is the location of the second target point. For example, the second measurement point and the second target point are golf holes. To obtain second measurement data between the observation point O and the second measurement point B, the measuring device 001 measures the second distance d2 and the second inclination angle θ2 of the line OB connecting the observation point O and the second measurement point B relative to the direction of gravity. For example, the second inclination angle θ2 is the inclination angle of the measuring device 001 relative to the direction of gravity, as measured by the angle sensing module 120 when the objective lens 113 is aligned with the second measurement point B.

[0059] The processor 300 of the measuring device 001 determines the target data between the first target point and the second target point based on the first measurement data d1 and the second measurement data d2 and θ2 output by the measuring component 100. The first distance d1 and the second distance d2 are obtained by the distance measurement module of the measuring device 001, and the second inclination angle θ2 is obtained by the angle sensing module. After receiving the above measurement data obtained by the distance measurement module 110 and the angle sensing module 120, the processor 300 of the measuring device 001 determines the target distance and target slope angle in the target data through triangulation. The calculation method is as follows:

[0060] The target slope angle α is calculated by taking the horizontal plane containing the first target point as the reference plane and calculating the angle between the line connecting the first and second target points relative to the reference plane. A positive value for α indicates that the second target point is higher than the first; a negative value for α indicates that the second target point is lower than the first; and a zero value for α indicates that the second target point is at the same height as the first.

[0061] During the game of golf, a user can use golf ball 003 as the first target point and hole 004 as the second target point. Using the measuring device 001 provided in this manual, the target distance L and target slope angle α between the golf ball and hole 004 can be obtained. During measurement, the user stands next to golf ball 003, with measuring device 001 positioned above it. The location of measuring device 001 is the observation point. The user places measuring device 001 at eye level and obtains first measurement data between measuring device 001 and a first measurement point A. First measurement point A can be a point on golf ball 003. The user uses a telescope to observe the location of golf ball 003 and determine the first measurement point A to be measured. Alternatively, the user can rotate measuring device 001 to a vertically downward viewing position without using the telescope to perform the measurement. The first measurement data includes a first distance d1 between the observation point and the first measurement point A, as well as a first slope angle θ1. In this measurement method, the first slope angle is automatically set to 0°.

[0062] The user adjusts the measuring direction of measuring device 001 and uses its telescopic system to observe the location of hole 004, determining the second measuring point B to be measured. Second measuring point B can be a point on the edge or inside of hole 004, or a point on the flagpole inside hole 004. Measuring device 001 acquires second measurement data between itself and second measuring point B. This second measurement data includes a second distance d2 and a second inclination angle θ2 between the observation point and second measuring point B. In this measurement method, first measuring point A coincides with the first target point, and second measuring point B coincides with the second target point.

[0063] FIG7 shows a schematic diagram of the use of a measurement device 001 according to some embodiments of this specification. Observation point O is the location of measurement device 001 when a user takes a measurement. In this measurement method, observation point O is neither above the first target point nor above the second target point.

[0064] The first measurement point A is the location of the first target point. For example, the first measurement point and the first target point are the hitting points. To obtain the first measurement data, the measuring device 001 measures the first distance d1 between the observation point O and the first measurement point A, as well as the first inclination angle θ1 of the first connecting line OA relative to the direction of gravity. The first connecting line OA is the connecting line between the observation point O and the first measurement point A. Specifically, the user can hold the measuring device 001 and align the objective lens 113 of the measuring module with the first measurement point A for measurement. The distance measurement module 110 in the measuring device 001 obtains the first distance d1, and the angle sensing module 120 obtains the first inclination angle θ1 of the measuring device 001 relative to the direction of gravity.

[0065] The second measurement point B is the location of the second target point. For example, the second measurement point and the second target point are golf holes. To obtain the second measurement data, the measuring device 001 measures the second distance d2 between the observation point O and the second measurement point B, as well as the second inclination angle θ2 of the second connecting line OB relative to the direction of gravity. The second connecting line OB is the connecting line between the observation point O and the second measurement point B. Specifically, the user can hold the measuring device 001 and align the objective lens 113 of the measuring module with the second measurement point B for measurement. The distance measurement module 110 in the measuring device 001 obtains the second distance d2, and the angle sensing module 120 obtains the second inclination angle θ2 of the measuring device 001 relative to the direction of gravity.

[0066] In order to obtain the target data between the first target point and the second target point, the measuring device 001 also measures the angle β between the first connecting line OA and the second connecting line OB. Specifically, when the user holds the measuring device 001 and aligns the objective lens 113 of the measuring module with the first measuring point A, the angle sensing module 120 of the measuring device 001 can obtain the first angle vector of the measuring device 001 relative to the reference coordinate system. When the user holds the measuring device 001 and aligns the objective lens 113 of the measuring module with the second measuring point B, the angle sensing module 120 of the measuring device 001 can obtain the second angle vector of the measuring device 001 relative to the reference coordinate system. Then calculate the angle Alternatively, when the user holds the measuring device 001 and aligns the objective lens 113 of the measuring module from the first measuring point A to the second measuring point B, the angle sensing module 120 can record the rotation angle and then convert the angle β from the rotation angle.

[0067] The processor of the measuring device 001 determines the target data between the first target point and the second target point based on the first measurement data d1, θ1 and the second measurement data d2, θ2 output by the measurement component. The first distance d1 and the second distance d2 are obtained by the distance measurement module of the measuring device 001, and the first inclination angle θ1, the second inclination angle θ2, and the angle β between the first connecting line OA and the second connecting line OB are obtained by the angle sensing module. After receiving the above measurement data obtained by the distance measurement module and the angle sensing module, the processor of the measuring device 001 determines the target distance and target slope angle in the target data through triangulation. The calculation method is as follows:

[0068] The target slope angle α is calculated by taking the horizontal plane containing the first target point as the reference plane and calculating the angle between the line connecting the first and second target points relative to the reference plane. A positive value for α indicates that the second target point is higher than the first; a negative value for α indicates that the second target point is lower than the first; and a zero value for α indicates that the second target point is at the same height as the first.

[0069] In a golfing application scenario, a user can use a golf ball 003 as the first target point and a hole 004 as the second target point, and use a measuring device 001 to obtain a target distance L and a target slope angle α between the ball and the hole 004. During measurement, the user stands away from the golf ball 003. The location of the measuring device 001, or in other words, the location of the eyepiece of the measuring device 001, is the location of the observation point. The user observes the location of the golf ball 003 through the telescopic system of the measuring device 001 and determines the first measurement point A to be measured. The first measurement point A can be a point on the golf ball 003. The user observes the location of the golf ball 003 through the telescopic system and determines the first measurement point A to be measured. The measuring device 001 obtains first measurement data between itself and the first measurement point A. The first measurement data includes a first distance d1 and a first slope angle θ1 between the observation point and the first measurement point A.

[0070] The user rotates their head, simultaneously adjusting the device's measurement direction. Using the telescopic system of measuring device 001, they observe the location of hole 004 and determine the second measurement point B to be measured. Second measurement point B can be a point on the edge or inside of hole 004, or a point on flagpole 005 within hole 004. Measuring device 001 acquires second measurement data between itself and second measurement point B. This second measurement data includes a second distance d2 and a second inclination angle θ2 between the observation point and second measurement point B.

[0071] In addition, the measuring device 001 also obtains the angle the device rotates during the measurement process from the first measuring point A to the second measuring point B. This is the angle between the first line connecting the observation point and the first measuring point A and the second line connecting the observation point and the second measuring point B. In this measurement method, the first measuring point A coincides with the first target point, and the second measuring point B coincides with the second target point.

[0072] Fig. 8 shows a schematic diagram of the use of the measuring device 001 provided in some embodiments of this specification. The observation point O is the location of the measuring device 001 when a user stands at a first target point and holds the measuring device 001 for measurement.

[0073] In order to obtain the first distance in the first measurement data between the observation point O and the first measurement point A, the measuring device 001 measures the first distance d1, or obtains the first distance d1 input by the user or preset. In some embodiments, the user holds the measuring device 001 and adjusts the measuring direction to a vertical downward direction for measurement (i.e., the objective lens 113 is aimed at the ground for measurement). In some embodiments, the user can also obtain the first distance d1 through the laser ranging module as shown in Figure 4. For example, the user can measure the first distance d1 through the auxiliary ranging unit of the distance measurement module. When the measuring device 001 is kept horizontal, the auxiliary ranging unit can emit a vertically downward laser or ultrasonic wave to measure the first distance d1 during operation. In some embodiments, the first distance d1 is stored in the measuring device 001 as a default parameter. In some embodiments, the user can input or modify the first distance d1 into the measuring device 001 by referring to his or her actual height data. Among them, one possible way to refer to the height data is to use the height data minus 10 cm (the distance from the top of the head to the glasses) as the first distance d1. 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 device 001 automatically sets the first inclination angle of the line OA connecting the observation point O and the first measurement point A relative to the gravity direction to 0°.

[0074] The second measurement point B is a point on a reference object standing above the second target point. For example, the second measurement point B can be a point on a flagpole above the hole. The distance between the second measurement point B and the ground is a third distance d3. To obtain the second measurement data, the measuring device 001 measures the second distance d2 between the observation point O and the second measurement point B and the second inclination angle θ2 of the line connecting them relative to the direction of gravity. Specifically, the user can hold the measuring device 001 and align the objective lens 113 of the measuring module with the second measurement point B for measurement. The distance measurement module 110 in the measuring device 001 obtains the second distance d2, and the angle sensing module 120 obtains the second inclination angle θ2 of the measuring device 001 relative to the direction of gravity.

[0075] The processor of the measuring device 001 determines the target data between the first target point and the second target point based on the first measurement data d1, the second measurement data d2, θ2 and the third distance d3 output by the measuring component. Among them, the first distance d1, the second distance d2 and the third distance d3 are obtained by the distance measurement module 110 of the measuring device 001, and the first inclination angle θ1 and the second inclination angle θ2 are obtained by the angle sensing module 120. After the processor of the measuring device 001 receives the above-mentioned measurement data obtained by the distance measurement module and the angle sensing module, it obtains the target distance and target slope angle in the target data through the quadrilateral measurement method. When the third distance d3 is approximately equal to the first distance d1, the approximate calculation method of the target distance L is as follows: Target distance L = d2 Target slope angle α = θ2-90°

[0076] The target slope angle α is calculated by taking the horizontal plane containing the first target point as the reference plane and calculating the angle between the line connecting the first and second target points relative to the reference plane. A positive value for α indicates that the second target point is higher than the first; a negative value for α indicates that the second target point is lower than the first; and a zero value for α indicates that the second target point is at the same height as the first.

[0077] In a golfing application scenario, the user can select golf ball 003 as the first target point and first measurement point A. The user can also select hole 004 as the second target point and a specific point above hole 004 as second measurement point B. During measurement, the user stands next to golf ball 003. The measurement device 001 is located at the observation point. Based on the measurement data between the observation point and first measurement point A and second measurement point B, the target distance L and target slope angle α between the ball and hole 004 are obtained. The distance between the observation point and first measurement point A is first distance d1. First distance d1 is roughly equivalent to the distance from the user's eyes to the ground.

[0078] The user observes a point on the flagpole through the telescopic system of measuring device 001 and determines the second measuring point B to be measured. Second measuring point B is a point on the flagpole. The distance between second measuring point B and hole 004 is a third distance d3. Measuring device 001 acquires second measurement data between the observation point and second measuring point B. The second measurement data includes the third distance d3 between the observation point and second measuring point B. In this measurement method, first measuring point A coincides with the first target point, and second measuring point B is above the second target point.

[0079] In some embodiments, the user visually determines the third measurement point on the flagpole. The principle of determination is to make the second height as equal as possible to the first height. In other words, the user measures a point on the flagpole that is approximately the same height as the user (actually, the distance between the user's eyes and the ground).

[0080] Of course, the human eye can't accurately locate the third measurement point at the same height as the first in every measurement. The smaller the difference between the second and first heights, the smaller the error in estimating the distance between the first and second target points using the distance between the observation point and the third measurement point. When the user is closer to the flagpole, the height of the third measurement point can be estimated more accurately. Although this requires higher accuracy, the overall result is satisfactory due to the more accurate estimation of the second height. Similarly, when the user is farther from the flagpole, the distance accuracy requirement becomes lower. Although the estimation of the second height is less accurate, the result is still acceptable for lower accuracy requirements.

[0081] In summary, the measuring device 001 provided in this specification is capable of determining the target distance and target slope angle between two target points using various measurement methods. A single measuring device 001 may include one or more measurement methods. Under different measurement methods, the measuring device 001 selects different measurement points or observation points for measurement, obtaining measurement data between the observation points and the measurement points. Target data is inferred based on the observation data. The measuring device 001 provided in this specification is adaptable to the complex topographical conditions of the green 002 and can obtain highly accurate measurement and target data for short-range measurements within the confines of the green 002.

[0082] In order to display the obtained target data, the measuring device 001 may further include an output device. The output device is used to display the target data in the form of visual display or voice. The output data may be all the target data or part of the target data. Part of the target data may be selectively output by the system according to the importance of the data, or may be set according to the user's choice. In some embodiments, the output device may include a display for displaying the target data. The display may be an LCD display, an OLED display, or a combination of the two. In some embodiments, the output device may include a speaker for voice broadcasting of the target data. In some embodiments, the output device may include both a display and a speaker.

[0083] Fig. 9 shows a schematic diagram of a display interface provided according to some embodiments of the present disclosure. When measuring device 001 is used to measure, the data displayed in the display interface of display 400 include target distance 410 and target slope angle 420. The target distance unit shown in Fig. 9 is Y (yard). The unit of target distance can be any common length unit such as meter, decimeter, centimeter, foot, inch, etc. The left side of the target slope angle shown in Fig. 9 shows an icon 430 for indicating the data type. Measurement mode icon 440 represents which measurement mode among multiple measurement modes the measuring device 001 is using.

[0084] In order to better utilize target data to assist golfers in putting, after obtaining target data between the first target point and the second target point, the measuring device 001 further: outputs a shot suggestion from the first target point to the second target point based at least on the target data. When the target distance is the distance between the golf ball 003 and the hole 004, and the target distance is less than or equal to 50 meters, the ball 003 is close to the green 002 or on the green 002. At this point, the shot suggestion obtained based on the target data is instructive for the golfer's subsequent operations. The shot suggestion includes one or more of shot speed, shot angle, or shot force. In some embodiments, a shot parabola is estimated based on the target distance and the target slope angle, and a shot angle or shot speed suggestion based on the parabola is provided.

[0085] Furthermore, in order to improve the accuracy of the batting advice, the measuring device 001 may also include a wind measurement module. The wind measurement module is communicatively connected to one or more processors, and can obtain wind speed data and / or wind direction data during operation. The wind speed data represents the size of the wind vector signal, and the wind direction data represents the direction of the wind vector signal. The measuring device 001 may also include a temperature measurement module. The temperature measurement module is communicatively connected to one or more processors, and can obtain temperature data during operation. The environmental data includes one or more of wind speed data, wind direction data, or temperature data. The measuring device 001 outputs the batting advice based on the environmental data and target data of the measuring device. For example, when the wind direction data indicates that it is a headwind at a certain moment, the recommended value for batting strength in the batting advice will be greater than when there is no wind. When the wind direction data indicates that it is a tailwind at a certain moment, the recommended value for batting strength in the batting advice will be smaller than when there is no wind.

[0086] In some embodiments, the measurement device 001 may also output shot suggestions. For example, the measurement device 001 may display one or more of the shot suggestions on a display. For example, the measurement device 001 may voice-announce one or more of the shot suggestions through a speaker. For another example, the user may manually select which shot suggestions to output, or may directly output according to the system default settings.

[0087] In summary, the measuring device provided in this specification can obtain the target distance and target slope angle of the line connecting two target points based on the measurement data between the observation point and the first and second measurement points. The position of the first measurement point is associated with the first target point, and the position of the second measurement point is associated with the second target point. The measuring device provided in this specification can deduce the relationship between the two target points by combining the relationship between the observation point and the measurement point, and the relationship between the measurement point and the target point. This measuring device can adapt to complex measurement scenarios and is simple to use and user-friendly.
