Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Also, not all combinations of features described in the embodiments are essential to the means of solving the invention.

FIG. 1 shows the configuration of the ranging system 500 according to the present embodiment. The distance measurement system 500 is a system that measures the distance and direction to the distance measurement target point and displays highly accurate position information about the distance measurement target point obtained based on the measurement result to the user. In this embodiment, in order to support a round on a golf course, a user who is a golf player can use a pin flag on the green or a fairway from any position on the course where the user is located, such as a tee ground, a fairway, or a green. An example of using the distance measuring system 500 in measuring the distance and orientation to an arbitrary shot target point will be described. In addition, measuring the distance and the direction to the distance measurement target point is also simply referred to as distance measurement or distance measurement. The distance measuring system 500 includes a distance measuring device 1 and a display device 20.

FIG. 2A shows the configuration of the distance measuring device 1 according to the present embodiment. The distance measuring device 1 is a device that measures the distance and the direction to the distance measuring target point. Here, the distance is not limited to the horizontal distance, but includes the vertical distance (that is, the height difference). The distance measuring device 1 includes a housing 9, a light projecting unit 100, a reticle plate 140, an eyepiece 150, a control unit 132, a detection unit 200, a conversion unit 240, a posture sensor 250, an orientation sensor 260, a communication device 270, and a processing unit. It is equipped with 300. Here, the direction in which the light projecting unit 100 emits the measurement light, that is, the arrow direction of the light beam B ₃ is the front, and the opposite direction, that is, the arrow direction of the light ray A ₃ is the rear.

The housing 9 is a case for holding other components of the distance measuring device 1 inside. An operation button 133 for operating the distance measuring device 1 when pressed by the user is provided on the upper surface of the housing 9.

The light projecting unit 100 is a unit that projects the measured light onto the object a plurality of times. The light emitting unit 100 includes a light emitting unit 130, an upright prism 120, and an objective lens 110.

The light emitting unit 130 emits pulsed measurement light (that is, light ray B ₁ ) toward the upright prism 120 at regular intervals using a light source. As the light source, for example, a semiconductor laser that oscillates infrared rays can be adopted. In one distance measuring operation, the light emitting unit 130 emits a predetermined number, for example, 320 pulse-shaped measurement lights, in a fixed cycle, for example, in a cycle of 500 to 700 μsec.

The upright prism 120 is an optical element that sends the measurement light emitted from the light emitting unit 130 forward and sends the incident light ray to the rear eyepiece 150. As the upright prism 120, for example, a roof prism, a polo prism, or the like can be adopted. The upright prism 120 has a dichroic reflecting surface 122 that reflects light in the visible light band and transmits light in the infrared band, and a total reflecting surface 124 that has high reflectance for both the visible light band and the infrared band. , 126. The measurement light (ray B ₁ ) passes through the dichroic reflecting surface 122 in the upright prism 120, is reflected by the total reflecting surface 124, and propagates forward in the housing 9 as the light ray B ₂ . The incident ray (ray A ₁ ) is reflected by the dichroic reflecting surface 122, the

total reflecting surface

124, 126 and other reflecting surfaces in the upright prism 120. As a result, the inverted mirror image formed by the incident light beam is inverted into an upright mirror image.

The objective lens 110 is an optical element that collimates the light ray B ₂ output from the upright prism 120 and sends it to the front of the housing 9 as the light ray B ₃ .

The reticle plate 140 is arranged at the focal position of the objective lens 110. The reticle plate 140 has a collimation index and a display unit (both not shown). The collimation index has a shape such as a crosshair, a rectangular frame, or a circular frame. The collimation index may be formed by printing, etching or the like on a plate transparent to visible light, or may be displayed by using a transmissive liquid crystal display. The display unit uses a transmissive liquid crystal display or the like to show the user the measurement result of the distance to the object by characters, images, or the like. Instead of providing the display unit directly on the reticle plate 140, a reflective liquid crystal display and an optical system that guides a display image using the liquid crystal display to the reticle plate 140 may be used. In addition to the distance measurement result, the display unit may also display the remaining battery level, alert, clock, and the like.

The eyepiece 150 is an optical element that collects incident light rays and sends them _rearward as light rays A3. Inside the housing 9, its front end faces the rear end of the upright prism 120.

The upright prism 120, the objective lens 110, the reticle plate 140, and the eyepiece lens 150 constitute a collimation section in which the user collimates the distance measuring device 1 with respect to the object. The collimation unit shares a part of the optical system with the light projecting unit 100, whereby the apparent optical axis of the light projecting unit 100 and the collimation unit coincide with each other in the distance measuring device 1.

Among the light reflected or scattered from the object located in front of the distance measuring device ₁ , the light ray A1 propagating within the range of the viewing angle of the objective lens 110 is incident on the collimation portion. The light ray A ₁ is focused as the light ray A ₂ through the objective lens 110, and is emitted as the light ray A ₃ behind the distance measuring device 1 through the upright prism 120, the reticle plate 140, and the eyepiece lens 150. This allows the user to observe an upright image of the object through the eyepiece 150.

The collimation index arranged on the reticle plate 140 is superimposed on the image of the object observed by the user through the eyepiece 150. As a result, the user collimates the distance measuring device 1 with the object by superimposing the collimation index on the image observed through the eyepiece 150. In this case, as described above, the light projecting unit 100 and the collimation unit have the same apparent optical axis, so that the measurement light is irradiated to the position indicated by the collimation index.

The control unit 132 is a unit that controls the intensity, the number of times of emission, the period, etc. of the measured light emitted from the light projecting unit 100 (light emitting unit 130). Further, the control unit 132 transmits the emission timing of the measurement light to the processing unit 300. As a result, the processing unit 300 can process the detection signal of the reflected light output from the detection unit 200 in response to the projection of each measurement light by the light projecting unit 100. The control unit 132 starts the distance measuring operation described later by receiving an operation signal generated by the user pressing the operation button 133 provided on the housing 9.

The detection unit 200 is a unit that detects reflected light from an object and outputs a detection signal in the form of an electric signal. The detection unit 200 includes a light receiving lens 210, a band transmission filter 220, and a light receiving element 230.

The light receiving lens 210 is an optical element that collects the reflected light (that is, the light ray C ₁ ) from the object and sends it to the light receiving element 230 as the light ray C ₂ . The light receiving lens 210 has an optical axis different from that of the objective lens 110 of the light projecting unit 100.

The band transmission filter 220 is an optical element that transmits light in a narrow band including reflected light and blocks or attenuates light in other bands. The band transmission filter 220 is arranged behind the light receiving lens 210.

The light receiving element 230 is an element that receives reflected light and outputs an electric signal (also referred to as a light receiving signal) corresponding to the intensity thereof. As the light receiving element 230, for example, a photodiode, a phototransistor, or the like having sensitivity to the band of the measurement light can be adopted. The light receiving element 230 is arranged behind the band transmission filter 220. From the viewpoint of eliminating the influence of the background light on the measurement light, it is preferable that the light receiving area of the light receiving element 230 is smaller.

In the detection unit 200 having the above configuration, the light ray C1 reflected or scattered from the object located in _front of the light receiving lens 210 is incident on the light receiving lens 210. The light ray C ₁ is condensed by the light receiving lens 210, passes through the band transmission filter 220 as the light ray C ₂ , and is received by the light receiving element 230. The light receiving element 230 outputs a light receiving signal corresponding to the intensity of the received light toward the conversion unit 240.

The conversion unit 240 includes, for example, an amplifier, which amplifies the light receiving signal output from the light receiving element 230. The conversion unit 240 may further convert the received light signal into a differential signal. Thereby, transmission noise can be reduced. The conversion unit 240 supplies the amplified light receiving signal as a detection signal to the processing unit 300.

The posture sensor 250 is a sensor or a group of sensors that detects the posture of the distance measuring device 1. The posture sensor 250 is provided on the housing 9 or a circuit board fixed in the housing 9, so that the detection result of the posture sensor 250 reflects the posture of the distance measuring device 1. Here, the posture means the inclination of the housing 9, and is represented by an angle (that is, an angle with respect to a horizontal plane or a vertical axis) θ in reference coordinates. For example, the angle can be detected from the detection result of the angular velocity and the acceleration by the tilt sensor such as the angular velocity sensor and the acceleration sensor. The measurable angle range is, for example, ± 89 degrees. These detection results are transmitted to the processing unit 300.

The azimuth sensor 260 is a sensor that detects the direction (that is, azimuth) φ in the horizontal plane to which the distance measuring device 1 faces. The azimuth also includes the azimuth to the distance measurement target point. As the azimuth sensor 260, a geomagnetic sensor that detects the geomagnetism and determines the azimuth based on the geomagnetism can be adopted. The measurable azimuth range is, for example, ± 180 degrees. By pointing the distance measuring device toward the measurement target point, the direction of the measurement target point can be measured with reference to the current position.

The communication device 270 is a device for wirelessly communicating with the display device 20. As the communication device 270, for example, BLE (Bluetooth (registered trademark) Low Energy) can be adopted. As a result, the distance data obtained by measuring the distance by the distance measuring device 1 is transmitted to the display device 20.

The processing unit 300 is a unit that determines the distance and inclination to the object and the height of the object based on the detection signal output from the conversion unit 240 and the detection result output from the attitude sensor 250. The linear distance D to the object is determined by the time of flight method (TOF), that is, the detection unit detects the reflected light of the measurement light reflected by the object with respect to the projection of each measurement light by the light projecting unit 100. It is determined by determining the time (detection time of reflected light) T detected by 200 (light receiving element 230) and calculating from the determined detection time T of reflected light from the calculation formula Tc / 2 (c is the speed of light). be able to. Since the detection time T is the time required for the light to move a distance corresponding to the round trip from the measurement position where the measurement light is emitted to the object, the detection time T is halved in the calculation formula. The speed of light c will be multiplied. The inclination to the object can be determined from the detection result of the angle θ output from the attitude sensor 250. As shown in FIG. 2B, the distance to the object (that is, the horizontal distance) d and the height h of the object are calculated from the formulas Dcos (θ) and Dsin (θ) based on the linear distance D and the inclination θ, respectively. Can be decided. The straight line distance D may be used as the distance to the object.

When the processing unit 300 detects that the user presses the operation button 133 provided on the housing 9 of the distance measuring device 1, the processing unit 300 transmits an operation signal to the control unit 132 to start the distance measuring operation described later. The distance, inclination, and height determined as described above (data acquired by measuring the distance using these distance measuring devices 1 are referred to as distance measuring data) are displayed on the reticle plate 140. As a result, the distance data is superimposed on the image of the measurement object that the user observes through the eyepiece 150. At the same time, the processing unit 300 transmits the ranging data to the display device 20.

FIG. 3A shows the configuration of the display device 20 according to the present embodiment. The display device 20 is a device that displays the position information of the distance measurement target point obtained based on the distance measurement data transmitted from the distance measurement device 1. In the present embodiment, as an example, a wristwatch-type wearable device worn on the user's arm is used. The display device 20 includes a band 18 and a main body 20a.

The band 18 is a member for attaching the main body 20a to the user's arm (for example, the left arm). The band 18 is, for example, a stretchable band-shaped member, and both ends thereof are fixed to the upper side and the lower side of the main body 20a, respectively. The user can attach the main body 20a to the arm by extending the band 18, passing the arm through the loop composed of the main body 20a and the band 18, and contracting the band 18.

FIG. 3B shows the hardware configuration of the main body 20a of the display device 20. The main body 20a includes a housing 19 (see FIG. 3A), a storage device 21, a position sensor 22, a display device 25, a wireless communication device 26, an arithmetic processing device 27, and an operation device 29.

The housing 19 is a case for holding other components of the main body 20a inside. In the present embodiment, the housing 19 has, for example, a cylindrical shape having a height smaller than the width, but is not limited to this, and may have any shape as long as the components can be held inside.

The storage device 21 is a device that stores distance measurement data and the like obtained by measuring the distance with the distance measurement device 1 and transmitted from the processing unit 300. As the storage device 21, for example, a non-volatile memory can be adopted.

The position sensor 22 is a sensor that detects information regarding the current position of the display device 20. A satellite positioning system (GPS) device can be adopted as the position sensor 22. The information regarding the current position is the position information of the display device 20 when the position sensor 22 is operated, and may be represented by latitude and longitude as an example. Further, the position sensor 22 may detect the current time, that is, the time when the position sensor 22 is in operation.

The display device 25 is a device that displays the distance measurement data obtained by measuring the distance with the distance measuring device 1, the measurement time at which the distance was measured, and the like on the display screen 25a. As the display device 25, for example, a liquid crystal display can be adopted.

The wireless communication device 26 is a device for wirelessly communicating with a communication device other than the distance measuring device 1 and the display device 20. As the wireless communication device 26, for example, BLE (Bluetooth (registered trademark) Low Energy) can be adopted. The wireless communication device 26 may be paired with and further bonded to the communication device 270 of the distance measuring device 1 in advance or when the power is turned on.

The arithmetic processing device (CPU) 27 is a device that executes a dedicated program to operate each component of the display device 20 and express various functional units. The functional configuration of the display device 20 will be described later. The dedicated program is stored in, for example, a ROM (not shown), read by the CPU, and expanded in the RAM to be started.

The operation device 29 is a device for operating the display device 20. As the operation device 29, for example, a plurality of operation buttons provided on the side surface of the housing 19 of the display device 20 so as to be pressable by the user can be adopted. Further, a touch sensor provided so as to be superimposed on the display screen of the display device 25 may be adopted.

The display device 20 includes a storage unit 410, an acquisition unit 420, a position information acquisition unit 421, a calculation unit 450, a display unit 460, a notification unit 470, a setting unit 480, and a transmission unit 490.

The storage unit 410 stores the distance measurement data received from the distance measurement device 1 in the storage device 21. When the storage unit 410 acquires the distance measurement data by the acquisition unit 420 in response to the operation of the distance measurement device 1, the storage unit 410 displays information about the current position from the position information acquisition unit 421, that is, the display device 20 when the distance is measured. The position information of is acquired, and the distance measurement data and the information about the current position are stored as a set. In addition, map information and other information may be stored.

Information on the position and information on the current time may be stored as a set. In this example, the latitude X and the longitude Y of the measurement position, which is the information about the current position (for example, "x ₁ , y ₁ ", etc.), with respect to the measurement time (for example, "13:16") which is the information about the current time. , Measurement results of distance, altitude, and direction, which are distance measurement data (for example, "528y / 5y / N0E (north 0 degree east)", etc.) "are stored.

The acquisition unit 420 wirelessly communicates with the distance measuring device 1 using the wireless communication device 26, and measures the distance and the direction to the distance measuring target point using the distance measuring device 1. Data is acquired from the distance measuring device 1.

The map information includes information on these terrains (shapes on a plane) contained in the area and information on the elevation distribution within the area. In addition, the map information includes the position information of the target points such as the pin cup and the green edge on the green 620. In addition, the map information includes the position information of the attention target as the information about the golf course. The attention target may be, for example, a bunker 650, a pond / river 660, a penalty area 670, or the like. Further, the map information includes the position information of the caution line such as the OB line (for example, it is assumed that the map information is provided at the boundary between the obstacle 680 and the rough 640).

The position information acquisition unit 421 acquires information regarding the current position of the display device 20 by the position sensor 22. Information about the current position is given by latitude and longitude as an example. Further, the position information acquisition unit 421 may acquire information regarding the current time by the position sensor 22. By using the position information acquisition unit 421 when the distance measurement data is acquired from the distance measurement device 1 by the acquisition unit 420, information regarding the current position (that is, measurement position) and information regarding the current time when distance measurement is performed (that is, information regarding the current time). That is, the measurement time) can be detected. The various acquired information is transferred to the storage unit 410 and the calculation unit 450.

The calculation unit 450 calculates the position information of the distance measurement target point based on the distance measurement data and the information regarding the current position by the calculation processing device 27. Here, the position information of the distance measurement target point is based on the distance and direction (that is, the current position) to the distance measurement target point based on the current position (that is, the position of the display device) obtained from the distance measurement data. It may be (relative position information of the distance measurement target point). Further, the altitude (also referred to as height difference) of the distance measurement target point based on the altitude of the current position may be included. Further, the calculation unit 450 may calculate the position information of the distance measurement target point by adding the distance and direction to the distance measurement target point based on the current position obtained from the distance measurement data to the information regarding the current position. .. In such a case, the position information of the distance measurement target point is given as absolute position information represented by, for example, the latitude (X) and the longitude (Y) of the distance measurement target point.

By notifying, it becomes easy to find the shot golf ball. In addition, after calculating the position information of the intersection of the caution line and the route existing on the route connecting the current position to the distance measurement target point and storing the result, the user is asked to go to the intersection using the same method as described above. You may notify the approach of. This makes it possible to easily find the shot position when starting a shot from a place crossing the OB line, for example, on a course in which the OB line is set as a caution line.

The setting unit 480 sets the target point based on the map information. Here, the user displays the golf course on the display screen 25a and selects an arbitrary point on the course as a target point by using the operation device 29. The selected target point is set by being included in the map information and stored in the storage device 21 by the setting unit 480.

In addition, the display unit 460 displays a direction object that represents the direction to the distance measurement target point based on the current position by superimposing it on the map information. Therefore, as shown in FIG. 6B, the display unit 460 displays the golf course 600 based on the map information, and the green 620, which is the distance measurement target point, is superimposed on the golf course 600 from the tee ground 610, which is the current position of the display device 20.

The mark "◇" is displayed at the back of the river 660, and the calculated distance "488y" is displayed on the left side of the mark. From the display on the display screen 25a, the user can confirm the attention target located on the route connecting the current position on the golf course 600 to the measurement target point, thereby considering a route that bypasses the attention target. , It is possible to easily grasp the flight distance of a shot to prevent the ball from being dropped on the object of caution.

In addition, the display unit 460 displays a moving object that represents a moving route from the current position to the distance measurement target point by superimposing it on the map information. Therefore, as shown in FIG. 6D, the display unit 460 displays the golf course 600 based on the map information, and the green 620, which is the distance measurement target point, is superimposed on the golf course 600 from the tee ground 610, which is the current position of the display device 20. The movement path 697 to the pin position 621 of is displayed.

Further, when the movement route is represented by a straight line route, the user can grasp the shortest route from the current position to the measurement target point. When the shortest path from the current position to the measurement target point is represented, the path is also the shortest movement (flying) path of the ball assumed when the ball is shot. Therefore, the moving object can also represent the moving path of the ball. In addition, characters, symbols, etc. for distinguishing the movement path of the user and the movement path of the ball may be arranged close to the moving object.

Further, the display unit 460 displays the position information of the intersection of the route and the caution line when the calculation unit 450 determines that the caution line exists on the route connecting the current position to the distance measurement target point.

The user is a point on the fairway 630 that is different from the first or second point, which is the tee shot target, and is suitable for a third shot, for example, to be downhill to aim at the pin position 621 on the green. Select the point as the target point "■". In such a case, the calculation unit 450 selects the first point “●” on the fairway as the target of the tee shot, and the distance measuring device 1 measures the distance.

As a result, the user can know that the downhill has a distance of 70y and a height difference of -3y from the third point to the pin position 621.

FIG. 7D shows an example of displaying a moving object showing a moving route from a distance measuring target point to a target point. The user selects the fourth point "◎" on the fairway as the distance measuring target point, and measures by the distance measuring device 1. The calculation unit 450 calculates the position information and the altitude information of the fourth point based on the distance measurement data acquired from the distance measurement device 1. The display unit 460 displays the calculation result together with the direction object (arrow 698), and further displays the movement route 697 from the fourth point, which is the distance measurement target point, to the pin position 621 registered as the target point. .. Not limited to the target point registered in the map information, the movement route to the target point selected by the user may be displayed in the same manner. As a result, the user can know the movement route from the arbitrarily selected range-finding target point to the target point registered in the map information. Further, when the movement route is represented by a straight line route, the user can grasp the shortest route from the fourth point to the target point. When the shortest path from the current position to the measurement target point is represented, the path is also the shortest movement (flying) path of the ball assumed when the ball is shot. Therefore, the moving object can also represent the moving path of the ball. In addition, characters, symbols, etc. for distinguishing the movement path of the user and the movement path of the ball may be arranged close to the moving object.

The golf player who is the user measures the target shot point as the distance measurement target point using the distance measuring device 1, selects a club (count) based on the result, hits the golf ball, and hits the golf ball, and then hits the golf ball. Repeat the move to until the golf ball is brought onto the green. Here, the distance measuring device 1 executes a distance measuring operation each time the user presses the operation button 133 to measure the distance to the distance measuring target point, and displays the distance measuring data including the result on the display device 20. Send. When the display device 20 acquires the distance measurement data by the acquisition unit 420, the display device 20 stores the distance measurement data by the storage unit 410 together with the information regarding the current position (measurement position) and the information regarding the current time (measurement time) (see FIG. 4). .. Therefore, the measurement result of the distance reflecting the target shot flight distance of the user can be obtained from the history of the distance measurement data obtained by the user measuring the distance for each shot, and the actual shot of the user can be obtained from the history of the measurement position. The movement distance between shots that reflects the flight distance can be calculated. Therefore, the calculation unit 450 further reads the history of the information (measurement position) about the current position stored in response to the operation of the distance measuring device 1 from the storage device 21 to calculate the moving distance, and the display unit 460. Displays the calculated travel distance history in comparison with the history of the measurement result of the distance to the distance measurement target point included in the distance measurement data.

FIG. 8 shows an example of a contrast display between the history of the travel distance and the history of the measurement result of the distance. From the history of the stored distance measurement data (FIG. 4), the distance traveled from the first measurement position to the second measurement position (x2, y2) by arranging them in the first measurement position (x1, y1) | (x2). , Y2)-(x1, y1) | = 488y, which is displayed in comparison with the distance measurement result 528y. It means that the actual flight distance was 488y with respect to the target flight distance 528y of the tee shot. Also, the distance traveled from the second measurement position to the third measurement position (x3, y3) by arranging them at the second measurement position (x2, y2) | (x3, y3)-(x2, y2) | = 282y Is obtained and displayed in comparison with the distance measurement result 265y. This means that the actual flight distance was 282y with respect to the target flight distance of 265y on the second shot. From these comparison displays, the user can consider, for example, the selection of a club (count).

The position information is the position information of the distance measuring device 1 when the position sensor 280 is operated, and may be represented by latitude and longitude as an example. The obtained position information of the distance measuring device 1 is transmitted to the processing unit 300.

In the flow of distance measuring and display operation shown in FIG. 9, the distance measuring device 1 detects the position information of the distance measuring device 1 by using the position sensor 280 before step S110. Since the position information of the distance measuring device 1 is detected following the measurement of the distance and the direction to the object in steps S102 to S108, the obtained position information is the distance measured when the distance is measured by the distance measuring device 1. The position of the device 1 (that is, the measurement position) is shown. Then, in step S110, the processing unit 300 measures the distance measurement data including the horizontal distance d and the height difference h to the object calculated in step S106, and the direction φ of the object detected in step S108. It is transmitted to the display device 20 by using the communication device 270 together with the position information of the device 1.

On the other hand, in step S200, the display device 20 acquires distance measurement data from the distance measurement device 1 together with the position information of the distance measurement device 1 by the acquisition unit 420. As a result, the display device 20 displays the position information of the distance measuring device 1 (indicating the measurement position) independently of the information regarding the current position of the display device 20 detected in step S202 (simply indicating the position information of the display device 20). To get. In step S204, the display device 20 stores the distance measurement data in the storage device 21 together with the position information of the distance measurement device 1, the information regarding the current position of the display device 20, and the information regarding the current time (measurement time) by the storage unit 410. ..

Further, in step S206, the display device 20 calculates the position information of the distance measurement target point based on the distance measurement data and the information regarding the current position of the display device 20 by the calculation unit 450. Here, the distance measurement data is given as the distance and direction to the distance measurement target point with respect to the position of the distance measurement device 1. Therefore, the calculation unit 450 measures the distance and the direction to the distance measurement target point based on the position of the display device 20 based on the information about the current position of the display device 20 and the position information of the distance measurement device 1. Correct the data. Then, in step S208, the display unit 460 displays the topographical information at the distance measurement target point based on the map information on the display screen 25a of the display device 25, and is calculated based on the corrected distance measurement data. The position information of the distance measurement target point based on the position of the display device 20 is displayed. As a result, the user can use the distance measurement data obtained by the distance measurement device 1 at a place away from the user (that is, the display device 20) to obtain the position information of the distance measurement target point based on the position of the display device 20. Can be known.

Instead of the display device 20 correcting the distance measurement data, the distance measurement device 1 may correct the distance measurement data. In such a case, prior to step S200, the display device 20 acquires information on the current position by the position information acquisition unit 421 and transfers it to the distance measuring device 1, and prior to step S110, the distance measuring device 1 obtains the distance measuring device 1. Based on the position information of the device 1 and the information regarding the current position of the display device 20, the distance measurement data is corrected so as to indicate the distance and the direction to the distance measurement target point based on the position of the display device 20. In step S110, the distance measuring device 1 transmits the corrected distance measuring data to the display device 20, and in step S200, the display device 20 (acquisition unit 420) acquires the distance measuring data corrected by the distance measuring device 1. As a result, the user can use the distance measurement data obtained by the distance measurement device 1 at a place away from the user (that is, the display device 20) to obtain the position information of the distance measurement target point based on the position of the display device 20. Can be known.

Further, the distance measuring device 1 corrects the distance measuring data based on the information regarding the current position of the display device 20 and the position information of the distance measuring device 1, and the display device 20 receives the corrected distance measuring data. The position information of the distance measuring target point may be displayed on the display screen 25a as the distance and direction to the distance measuring target point based on the position of the distance measuring device 1, and may be further stored in the storage device 21. As a result, when the user measures the distance and direction to the distance measuring target point by himself / herself using the distance measuring device 1, the distance measuring data corrected by the distance measuring device 1 is moved to a place away from the distance measuring device 1. By transmitting to a certain display device 20, it is possible to display and record the position information of the distance measurement target point based on the position of the user who has performed the distance measurement on the display device 20.

In the distance measuring system including the distance measuring device 1d according to the modified example and the above-mentioned display device 20, the display unit 460 of the display device 20 may display the position information of the distance measuring device 1 on the display screen 25a.

Further, the notification unit 470 determines whether or not the distance measuring device 1 is outside the predetermined distance range from the current position of the display device 20, and if it is determined that the distance measuring device 1 is outside the distance range, the sound, light, and / Alternatively, vibration may be used to notify the distance of the distance measuring device 1. The user can confirm the current position of the distance measuring device 1 from the display on the display screen 25a, and can prevent the distance measuring device 1 from being misplaced or stolen by the notification by the notification unit 470.

Further, when the communication of the distance measuring device 1 is interrupted, such as when the display device 20 and the distance measuring device 1 cannot be paired, the notification unit 470 obtains the position information of the distance measuring device 1 acquired before the interruption. Based on this, it is determined whether or not the distance measuring device 1 is outside the predetermined distance range from the current position, and if it is determined that the distance measuring device 1 is outside the distance range, the sound, light, and / or vibration is used to determine the distance measuring device. You may inform the separation of 1. For example, a user who is a golf player moves on the fairway 630 toward the second shot point after the tee shot, and a caddy who measures the distance using the distance measuring device 1 moves the distance measuring device 1 behind the tee ground 610. Suppose you misplaced it. In such a case, as shown in FIG. 12, the display unit 460 displays the golf course 600 based on the map information, and superimposes the mark “x” indicating the current position of the display device 20 on the fairway 630. The latitude and longitude (x, y) of the current position are displayed on the left side of the display, and the position acquired from the range measuring device 1 before the communication is interrupted (the position of the range measuring device 1 when the distance was last measured). ) Is displayed behind the tee ground 610 (in the lower right direction of the drawing), and the latitude and longitude (X, Y) of the distance measuring device 1 are displayed on the right side thereof. Assuming that the distance that can be paired between the distance measuring device 1 and the display device 20 is, for example, 10 m, the notification unit 470 is the distance measuring device 1 that the user having the display device 20 finally acquired from the distance measuring device 1. When the distance from the position, that is, the distance from the rear of the tee ground 610 where the distance measuring device 1 is left behind is 10 m or more, this is detected and the warning mark 696 is blinked on the display screen 25a. The distance measuring device 1 may stop its operation by turning off the power when the communication with the display device 20 is interrupted. By the notification by the notification unit 470, the user can prevent the distance measuring device 1 from being misplaced or stolen.
