Description

Apparatus and Method for Measuring Distance

The present invention relates to a distance measuring apparatus and method, and more particularly, to a portable distance measuring apparatus and method capable of easily measuring a distance of a target object at a golf course or the like based on a laser.

In general, measuring the distance between a golfer and a certain point on the fairway or a hole cup on the green in a golf game acts as one of the decisive factors for having a successful game. Usually, the distance measurement on the fairway or the distance to the hole cup on the green depends on the golfer's experience and sense. feel confused

Conventionally, in order to measure the distance on the golf course, the distance between the golfer and the hole cup on the green is provided through a GPS (Global Positioning System) terminal in which the golf course information is input in advance. However, in this case, the GPS measurement error and the GPS terminal must be periodically updated, but it is almost impossible to continuously update data fluctuations such as a change in the structure of a golf course or the opening of a new golf course, so the continuous provision of accurate information is difficult. In fact, it is difficult.

In addition, it is possible to use a laser measuring device using laser measurement technology for distance measurement in golf, but the measurement equipment is bulky due to factors such as shooting an image for distance measurement or having a telephoto lens, so it is easy to carry during the game. Since it is very inconvenient and the price is also high, it is difficult to purchase except for professional golfers, so there was a problem that novice golfers who needed the distance measuring device the most could not use it.

1 is a perspective view showing a distance measuring device according to a preferred embodiment of the present invention.

As shown in FIG. 1 , the distance measuring device 100 is housed by the main body 110 . The main body 110 may be made of a small and lightweight shape and material for easy portability. The main body 110 may be configured in a shape that is easy for a user, for example, a golfer or a caddy, to grip by hand.

For example, the main body 110 may be configured so that a user can put the distance measuring device 100 in a pocket such as clothes or a bag while carrying it. In addition, the main body portion may be configured to further include a clip (not shown) on one side so that the user can attach the distance measuring device 100 to the user's bag, belt, clothing, hat, or the like. In this embodiment, a small and lightweight body part 110 of a rectangular shape will be described.

The respective parts are housed and accommodated by the body part 110 , and the overall data flow and interworking between the respective parts may be controlled by the controller 150 .

A display unit 130 capable of displaying information may be provided on the first side of the body unit 110, for example, on one side of the upper portion. A switch 122 of the selection unit 120 may be provided on the second side of the main body 110 , for example, on the other side of the upper portion. The switch 122 may input a signal for communication by the user to the distance measuring apparatus 100 .

The selector 120 may select a measurement mode and a normal mode according to a signal input through the switch 122 . For example, the selection unit 120 may select an operation mode of the distance measuring apparatus 100 based on the user's switch operation.

The operation mode includes a measurement mode and a normal mode. The measuring mode may refer to a mode in which the distance measuring apparatus 100 activates a distance measuring function for measuring a distance of a target. On the other hand, the normal mode may be a mode for disabling the distance measurement function.

As mentioned above, the selection unit 120 may include a switch 122 . The switch 122 may switch from the normal mode to the measurement mode. For example, when the user presses the switch 122 in the normal mode, the distance measuring apparatus 100 may be switched to the measuring mode to measure the distance by the measuring unit 140 .

The transition from the measurement mode to the normal mode is performed by pressing the switch in the measurement mode, lapse of a preset measurement mode period, controlling by the control unit 150, and releasing the switch from pressing (for example, the measurement mode by holding the switch pressed). is maintained) and the like.

The measuring unit 140 is provided on the third side of the main body 110 and may measure distance values to a plurality of target points based on the laser in the measuring mode. The measurement unit 140 may include a laser transceiver 142 and an operation unit 144 .

The laser transceiver 142 may be provided on one side of the front side of the main body 110 , and in the measurement mode, may transmit a laser toward a plurality of target points and receive reflected waves reflected by the plurality of target points. The calculator 144 may detect a signal transmitted and received by the laser transceiver 142 and measure a plurality of distance values, that is, a distance to a target point.

The control unit 150 is provided on the fourth side, for example, inside the body unit 110, based on a predetermined standard, detects at least one of a plurality of distance values measured by the measurement unit 140, and detects the detected The distance to the final target point may be detected based on at least one distance value and displayed on the display unit 130 .

The laser pointer unit 160 may be provided on the fifth side of the body unit 110 , for example, on the other side of the front side. The laser pointer unit 160 may generate a laser pointer toward the plurality of target points in the same direction as the laser transmission direction of the laser transceiver unit 142 in the measurement mode so that the user can easily aim the target.

Hereinafter, an operation process of the distance measuring apparatus 100 according to a preferred embodiment of the present invention will be described in more detail.

First, it is assumed that the user is playing a golf game in the field and carries the distance measuring device 100 . The user wants to measure the distance from the field to the long-distance target point, the hole cup. The user may take out the distance measuring device 100 he was carrying and input a signal using the switch 122 (eg, by pressing the switch 122 or touching the switch 122 , in this embodiment) It is assumed that a signal is input by the operation of pressing the switch 122).

When the switch 122 is pressed, the distance measuring device 100 is switched to the measuring mode. In the measurement mode, the user regards the flag next to the hole cup as the final target point and directs the laser transceiver 142 provided on the front of the distance measuring device 100 to the flag as the final target point, and in that state, the distance measuring device 100 ) can be shaken left and right several times or moved in a zigzag form.

3 is an exemplary view illustrating the display unit 130 that displays a guide message for guiding the distance measuring apparatus 100 to move in a measurement mode.

As shown in FIG. 3 , the control unit 150 requests to shake the body unit 110 left and right or in a zigzag form in a state in which the laser transceiver 142 provided in the measurement unit 140 is aimed toward the final target point. Messages such as "Aim at target and shake left and right or zigzag several times!" can be controlled to appear on the display. Such a message may be displayed on the display unit 130 at the start time of the measurement mode after the user presses the switch 122 .

Meanwhile, this message may be displayed in the normal mode by pressing the switch 122 before pressing the switch to start the measurement mode or by pressing the switch in a different way from pressing the switch to start the measurement mode.

For example, when the switch 122 is pressed once in the normal mode, a message is displayed, and when the switch 122 is pressed once more while the message is displayed, the distance measuring apparatus 100 may be switched to the measurement mode. Alternatively, in the general mode, if the switch 122 is pressed or pressed once for a short time, a message is displayed, and if the switch 122 is pressed for a relatively long time or the switch 122 is pressed two or more times in a row, it will be converted to the measurement mode. may be

4 is an exemplary diagram illustrating a state of moving the distance measuring apparatus 100 in a measurement mode.

As shown in FIG. 4 , according to a message displayed on the display unit 130 , the user may move the distance measuring apparatus 100 left and right or zigzag while aiming the laser at the final target flag in the measurement mode. That is, the distance measuring apparatus 100 is moved so that the distance to the final target is included in the plurality of measured distance values at least once.

Then, the laser transmitted by the laser transceiver 142 is transmitted several times to an object or flag next to the flag. Accordingly, the measurement unit 140 may measure a distance value to the flag at least one time or more and a distance value to an object near the flag at least one time or more.

That is, the measuring unit 140 transmits a laser toward a plurality of target points based on the movement of the main body 110 in the measurement mode and detects reflected waves reflected by the plurality of target points to measure a plurality of distance values. have.

5 shows a target point measured when the distance measuring apparatus 100 moves the laser aiming point in a zigzag pattern with respect to the flag in the measurement mode.

As shown in FIG. 5 , as the user moves the distance measuring apparatus 100 in a zigzag manner in the measurement mode, the aiming point of the laser is moved along paths A to H.

In this case, the measurement unit 140 may measure distance values of, for example, a plurality of target points A, B, C, D, E, F, G, and H. Here, the distance values of B, E, and G may have almost similar values because they are distance values to the final target point of the flag or flagpole. On the other hand, the distance values of A, C, D, F, and H are distance values from a flag or flagpole to a landmark such as a mountain or a tree, so they may have a relatively much larger value or a value exceeding the measurement limit.

6 is a flowchart illustrating an operation flow of the controller 150 of the distance measuring apparatus 100 .

As shown in FIG. 6 , the controller 150 may detect at least one of a plurality of distance values measured by the measuring unit 140 based on a predetermined criterion (step: S1 ). The control unit 150 may display the distance to the final target point on the display unit 130 based on the detected at least one distance value (step: S2).

More specifically, for example, according to an embodiment of the present invention, the controller 150 detects a distance value having the smallest magnitude among a plurality of distance values measured during the measurement mode, and finally determines the distance value having the smallest detected magnitude. The distance to the target point may be displayed on the display unit 130 .

7 is a flowchart for explaining a detailed operation flow of the controller 150 of the distance measuring apparatus 100 .

According to another specific embodiment of the present invention, as shown in FIG. 7 , the controller 150 may detect a distance value having the smallest magnitude among a plurality of distance values measured during the measurement mode (step S21). For example, in the description of the aforementioned example with reference to FIG. 5 , assuming that the distance value of E is the smallest, the controller 150 may detect a distance value corresponding to E.

Subsequently, the controller 150 may detect at least one distance value in which a difference between the detected distance value and the smallest distance value is less than or equal to a predetermined range among the plurality of distance values (step S22). For example, assuming that the predetermined range is plus/minus 5 Cm in the example described above, the controller 150 may detect distance values of B and G having a distance value substantially similar to E.

Next, the controller 150 may determine the distance to the final target point based on the smallest distance value and at least one distance value that is less than or equal to the predetermined range, and display it on the display unit 130 (step: S23). . For example, the control unit 150 calculates the average of the distance value of E detected in step S21 and the distance value of B and G detected in step S22, that is, the average of the distance values of E, B, and G The average value derived from ? may be determined as a distance value to the flag, which is the final target point, and displayed on the display unit 130 .

Meanwhile, the period of the measurement mode may be a predetermined period, for example, 5 seconds, 10 seconds, or the like. For example, when a predetermined period expires after the measurement mode is performed, the measurement mode may be terminated and converted to a normal mode.

Alternatively, the period of the measurement mode may be determined by a user input through the switch 122 . For example, when the user presses the switch 122 in the measurement mode, the measurement mode may be switched to the normal mode. On the other hand, if the measurement mode is maintained only when the switch 122 is continuously pressed, the measurement mode may be converted to the normal mode by releasing the press of the switch.

Meanwhile, in the measurement mode, the controller 150 detects a distance value with the smallest size among a plurality of distance values, and then measures when at least one distance value whose difference from the smallest distance value is less than or equal to a predetermined range is detected. You can also control it to exit the mode.

In this case, the controller 150 may determine the distance to the final target point based on at least one of a distance value having the smallest size and at least one distance value that is less than or equal to a predetermined range and display the determined distance on the display unit 130 . For example, the controller 150 calculates an average value of the distance value with the smallest size and at least one distance value that is less than or equal to a predetermined range, determines the distance to the final target point, and displays the determined distance value on the display unit 130 . You may.

8 is a flowchart for explaining the operation of the control unit 150 according to another embodiment of the present invention.

As shown in FIG. 8 , the controller 150 sets the plurality of distance values measured during the measurement mode to a first group having a relatively small distance value and a distance greater than a specific range from the distance values of the first group. It can be classified into a second group having a value (step: S31).

For example, in the example shown in FIG. 5 described above, the controller 150 classifies the distance values of B, E, and G having relatively small distance values into a first group, and the distance values of the first group Distance values of A, C, D, F, and H having a larger distance value in a more specific range, for example, several meters or several tens of meters may be classified into the second group.

Next, the controller 150 may display the distance to the final target point on the display 130 on the basis of one or more distance values included in the first group (step S32). For example, in the example described above, the controller 150 calculates the average value of the distance values of B, E, and G, and determines the average value as the distance value to the final target point through the display unit 130 . can be displayed

Next, the controller 150 determines the reliability of the distance to the final target point displayed on the display unit 130 according to the number of distance values belonging to the first group (step: S22), and displays the determined reliability information on the display unit ( 130) (step: S34).

The reliability may be determined according to the number of distance values belonging to the first group. For example, when the number of distance values belonging to the first group is less than a predetermined number (eg, 2), the reliability may be determined as “low”, and when the distance value is greater than or equal to the predetermined number, the reliability may be determined as “high”.

The controller 150 may display the determined reliability on the display 130 through letters, numbers, or symbols. For example, high confidence can be expressed using "high", "1", "Good", "^^", etc., and low confidence is expressed by "low", "2", "Bad", " ㅠ.ㅠ", etc. can be used to display it.

Meanwhile, the controller 150 may display specific letters, numbers, and symbols indicating high reliability on the display unit 130 , and may not display any display on the display unit 130 when the reliability is low.

The reliability display units 172 and 174 may include a first reliability display unit 172 indicating “high” reliability and a second reliability display unit 174 indicating “low” reliability. In this case, if the reliability is high, the first reliability indicator 172 may be turned on, and if the reliability is low, the second reliability indicator 174 may be turned on.

According to another embodiment, the distance measuring apparatus may include only the first reliability display unit 172 . In this case, the first reliability indicator 172 is turned on only when the reliability is high, and when the reliability is low, the first reliability indicator 172 is not turned on.
