In the implementation manner, the terminal equipment can accurately acquire the distance between the user and the green according to the information of the inflection point, so that the calculation accuracy can be improved.

The method for acquiring the inflection point information by the terminal device according to the position of the user is described in detail below:

The terminal equipment can determine the target tee according to the position of the user, and further uses the information of the inflection point corresponding to the target tee as the information of the inflection point of the fairway in the golf course.

In one example, the terminal device may obtain information of an inflection point corresponding to at least one serving table in the golf course in advance. In this way, after determining the target tee where the user is located, the terminal device may acquire information of the inflection point of the target tee in the inflection point information corresponding to the at least one tee.

In one possible implementation, the terminal device may obtain information of an inflection point corresponding to at least one serving table in the golf course from the server in advance, e.g., the terminal device may receive information of an inflection point corresponding to at least one serving table from the server when requesting map data of the golf course from the server. The server obtains information of inflection points corresponding to at least one service platform, and can refer to the terminal equipment to obtain related description of the information of the inflection points corresponding to the at least one service platform. In the implementation manner, the terminal equipment does not need to acquire the information of the inflection point corresponding to at least one sending table, so that the calculated amount of the terminal equipment can be reduced.

The inflection points included in the inflection point information corresponding to the billiard table satisfy the following conditions:

Within the lane contour, on the centerline, and a distance from a center point of the green that is greater than a first threshold; and the included angle between the first line segment and the second line segment is in a preset angle range, the first line segment is a connecting line with the central point of the green, and the second line segment is a connecting line with the central point of the service platform. Illustratively, taking a tee as a tee 1 as an example, the inflection points included in the inflection point information corresponding to the tee 1 satisfy the following conditions: within the lane contour, on the centerline, and a distance from a center point of the green that is greater than a first threshold; and the included angle between the first line segment and the second line segment is in a preset angle range, the first line segment is a connection line with the central point of the green, and the second line segment is a connection line with the central point of the service platform 1.

The embodiment of the application sets the inflection point in this way, aiming at: the condition of lane corner is confirmed to the user of being convenient for the user can adjust own batting dynamics, batting direction, improves batting accuracy.

In one possible implementation manner, when the inflection point information corresponding to the service platform includes a location of an inflection point, the inflection point included in the inflection point information is: and an inflection point corresponding to the maximum included angle in the preset angle range.

In addition, when the inflection point information corresponding to the billiard table includes positions of a plurality of inflection points, the inflection point corresponding to the maximum included angle within the preset angle range may be regarded as the target inflection point.

The application is arranged in such a way that: if the user hits down the golf ball at the inflection point corresponding to the maximum included angle within the preset angle range, the user can see the green at the inflection point, so that the user can accurately determine the subsequent batting strategy, and the user experience is improved.

Secondly, when the terminal equipment determines that the user is not in the tee according to the position of the user, the terminal equipment can acquire the information of the inflection point according to the position of the user and the map data of the golf course.

Wherein, the map data of the golf course includes: the ball track profile, the central line, the central point of the green, the central point of the ball track, and the central point of at least one service platform, the central line is: and connecting lines of the central point of the at least one service platform, the central point of the lane and the central point of the green.

If the user does not cross the lane starting point, the user still has an inflection point from the green, the user cannot see the green, and the terminal equipment can continuously recommend the inflection point for the user according to the position of the user, so that the user can accurately hit the ball.

In one possible implementation, the map data of the golf course further includes: the hole outline, according to the position of the user, obtains the information of the inflection point of the fairway in the golf course, including: detecting whether the position of the user is contained in the hole outline of a target hole, wherein the target hole is the hole selected by the user; if yes, acquiring information of inflection points of the fairway in the golf course according to the position of the user.

In fig. 1, at least one service table is exemplified as including a service table 1 and a service table 2. The area of the golf course other than the tee 11, fairway 12, green 13, and hole 14 may be referred to as the barrier 15. Taking the tee 11 as a rectangle in fig. 1 as an example, there is a corner in the lane 12 from the tee 11 to the green 13 in fig. 1, and the user cannot see the green 13 from the tee 11.

The golf watch may calculate a distance from the user to a specified point based on preset golf course data and positioning data of the golf watch to assist the user in formulating a batting strategy. The golf watch can calculate the distance between the user and the green according to the positioning data of the golf watch and the position of the green in the golf course data. However, when the distance calculated by the golf watch is the straight line distance from the user to the green, referring to fig. 1, when there is a corner between the user and the green, the straight line distance calculated by the golf watch is not the distance between the actual user and the green, and the distance calculation is inaccurate, which affects the accuracy of the hitting of the user.

For example, the user may turn on the golf mode in the terminal device so that the terminal device obtains relevant data of the user while playing golf. Wherein the terminal device is responsive to the golf mode being on, the location of the terminal device may be obtained. When the terminal device detects that the map data of the golf course where the position of the terminal device is located is not stored in the terminal device, the terminal device may display the name of the golf course where the position of the terminal device is located according to the position of the terminal device.

The instruction to start the golf motion may be, for example, to turn on the golf mode for the user, or to operate a button of "start to perform the golf motion" or to input a voice of "start to perform the golf motion", which is not limited in the embodiment of the present application.

In one example, the terminal device may also display the name of the golf course around the location of the terminal device. As shown in fig. 4, the terminal device may display the name of golf course 1 where the terminal device is located, and the names of golf courses around the location of the terminal device, such as course 2 and course 3. The user can select the name of the golf course where the user is located, and trigger the terminal device to download the map data of the golf course. Illustratively, if the user selects the course 1, the terminal device can download map data of the course 1.

In one example, the terminal device can request the server to download map data of the court 1. Wherein the server may store map data for a plurality of golf courses. In one example, the map data for the golf course may be uploaded to a server by a worker after mapping the golf course, as embodiments of the application are not limited in this respect.

In one embodiment, if the terminal device has stored therein map data for a golf course, such as when a user has arrived at the golf course, the terminal device has downloaded the map data for the golf course, the terminal device may have stored therein map data for the golf course. Illustratively, the location of the terminal device may be obtained in response to the golf mode being on.

The information of the inflection point may include: the location of the inflection point. In one example, each tee may correspond to at least one inflection point, or each tee may correspond to a range of inflection points.

In the embodiment of the application, the terminal equipment can acquire the information of the inflection point in the position contained in the map data of the golf course. The terminal device may acquire the candidate inflection point in a location included in the map data of the golf course, and then determine the inflection point according to the candidate inflection point. In one example, the candidate inflection point needs to satisfy the following condition:

Condition 1: is within the lane contour.

Condition 2: on the centerline.

Condition 3: the linear distance from the center point of the green is greater than a first threshold value. The first threshold may be predefined, and illustratively, the first threshold may be 35 meters.

Condition 4: and connecting the first line segment with the central point of the green to obtain a second line segment, wherein the included angle between the first line segment and the second line segment is in a preset angle range. The preset angle range may be predefined, and exemplary, the preset angle range may be 40 ° -180 °.

The 4 conditions are set as above in the embodiment of the present application because: in one aspect, the corner of the tee to the green is in the lane and the inflection point is also in the lane contour. On the other hand, in order to assist the user in striking the golf ball to the inflection point, the inflection point is disposed on the center line, not at the edge of the course contour, thus giving the user some opportunity for trial and error. If the inflection point is set at the edge of the lane contour, the falling point of the golf ball may deviate from the lane contour, which increases the difficulty of the user in hitting the golf ball.

On the other hand, the straight line distance between the inflection point and the central point of the green is set to be larger than a first threshold value, and the first threshold value is the position where the user can see the green, so that the user can be assisted in determining the inflection point, and if the user hits a golf ball to the inflection point, the user can see the green, and the next batting of the user is facilitated. On the other hand, the included angle between the first line segment and the second line segment is set within the preset angle range, so that the inflection point can be conveniently determined at the corner of the lane, the inflection point can be determined by the user, and if the user hits the golf ball to the inflection point, the green can be seen, and the next batting of the user is facilitated.

The terminal device can obtain candidate inflection points according to the above 4 conditions, and the embodiment of the application does not limit the order of using the above 4 conditions by the terminal device. For example, the terminal device may acquire the candidate inflection points in the order of condition 1 to condition 4. For example, the terminal device may consider a location within the lane contour as the first candidate inflection point. Among the first candidate inflection points, the terminal device may take the first candidate inflection point located on the center line as the second candidate inflection point. The terminal device may calculate a distance between each second candidate inflection point and a center point of the green, and use the second candidate inflection point having a distance greater than the first threshold value as a third candidate inflection point. The terminal device may connect each third candidate inflection point with the center point of the green to obtain a first line segment, connect each third candidate inflection point with the center point of the billiard table to obtain a second line segment, and obtain an included angle between the first line segment and the second line segment corresponding to each third candidate inflection point. The terminal device may use a third candidate inflection point corresponding to the included angle in the preset angle range as the candidate inflection point.

It should be understood that, for different tee boxes, when the terminal device calculates the included angle between the first line segment and the second line segment, the terminal device may connect the third candidate inflection point with the center point of the different tee box to obtain the second line segment. Illustratively, the at least one service platform includes a service platform 1 and a service platform 2, when the terminal device obtains inflection point information corresponding to the service platform 1, the terminal device may connect each third candidate inflection point with a center point of the service platform 1 to obtain a second line segment, so as to calculate an included angle between the first line segment and the second line segment. When the terminal device obtains inflection point information corresponding to the billiard table 2, the terminal device may connect each third candidate inflection point with the center point of the billiard table 2 to obtain a second line segment, so as to calculate an included angle between the first line segment and the second line segment.

In one embodiment, the information of the inflection point corresponding to the billiard table may include a location of the inflection point. In one example, if the terminal device can screen to obtain multiple candidate inflection points according to the above 4 conditions, the terminal device may use the candidate inflection point with the largest included angle as the finally determined inflection point. Correspondingly, the inflection point information corresponding to the billiard table may include: the position of the candidate inflection point with the largest included angle. In one example, if the terminal device can screen to obtain a candidate inflection point according to the above 4 conditions, the terminal device may use the candidate inflection point as the finally determined inflection point.

In one embodiment, the information of the inflection point corresponding to the billiard table may include at least one inflection point position.

In one example, if the terminal device can screen to obtain multiple candidate inflection points according to the above 4 conditions, the terminal device may use the candidate inflection point with the largest included angle and the candidate inflection point with the smallest included angle as the finally determined inflection points. The arrangement is as follows: the condition of the corner of the lane is convenient for the user to determine, so that the user can adjust the hitting force, the hitting direction and the like of the user, and the falling point of the golf ball can be between the two inflection points.

In one example, if the terminal device can screen to obtain multiple candidate inflection points according to the above 4 conditions, the terminal device may use the candidate inflection point with the largest included angle, the candidate inflection point farthest from the green, and the candidate inflection point closest to the green as the finally determined inflection points. The arrangement is as follows: the method is convenient for the user to determine the inflection points closest to the green and farthest from the green, if the batting capability of the user is limited, the user can be guided to batte to the inflection point closest to the green, and in addition, the terminal equipment also takes the candidate inflection point with the largest included angle as the inflection point, so that the user can conveniently determine the condition of the corner of the lane.

In one embodiment, the inflection point range may be included in the information of the inflection point corresponding to the billiard table, and the inflection point range may represent the location range. Wherein the inflection point range includes a location of at least one inflection point. In one example, if the terminal device can screen to obtain multiple candidate inflection points according to the above 4 conditions, the terminal device can determine the candidate inflection point with the largest included angle and the candidate inflection point with the smallest included angle, for example, the terminal device can determine the inflection point range by taking the two candidate inflection points as two points on a circle. The arrangement is as follows: the condition of the corner of the lane is convenient for the user to determine, and the user can adjust the hitting force, the hitting direction and the like of the user, so that the falling point of the golf ball can be between the two inflection points. The embodiment of the application does not limit the shape of the inflection point range, and can be rectangular, square, triangular and the like.

In one possible scenario, where there are no corresponding inflection points for some tee boxes in the golf course, the terminal device need not obtain information for the corresponding inflection points for those tee boxes.

In one embodiment, in a scenario in which the terminal device requests the server to download map data of the golf course, because the map data of the golf course is stored in advance in the server, the server may acquire information of an inflection point corresponding to the tee according to the scenario of the map data of the golf course, so that the server may transmit the map data of the golf course and the information of the inflection point corresponding to the tee to the terminal device when the terminal device requests the server to download the map data of the golf course. In such an embodiment, the server does not obtain the information of the inflection point corresponding to the tee, so that the processing time of the terminal device can be reduced, and the information of the inflection point corresponding to the tee can be obtained at the same time when the map data of the golf course is downloaded.

S302, the position of the user is obtained.

The terminal equipment comprises a positioning module, and the terminal equipment can acquire the position of the terminal equipment through the positioning module. Because the user wears the terminal device, the terminal device can take the location of the terminal device as the location of the user.

In one example, the terminal device may be turned on in response to a golf mode and may obtain the location of the user. In one example, the terminal device may periodically acquire the location of the user, thereby performing S303-S304.

In one example, because a plurality of holes are included in the golf course, the user may select a target hole on the terminal device when the golf mode is turned on or when the golf operation is started, the target hole being a hole in which the user desires to enter a ball. In this example, after the terminal device obtains the position of the user, it may detect whether the position of the user is included in the hole contour of the target hole, if the position of the user is included in the hole contour of the target hole, the terminal device may execute S303-S304, and if the position of the user is not included in the hole contour of the target hole, which indicates that the user may have deviated from the hole contour of the target hole, the terminal device may not execute S303-S304.

S303, determining a target service platform where the user is located according to the position of the user.

The terminal device may obtain the position of each service platform according to the map data, and the terminal device may use the service platform where the position of the user is located as the target service platform. In one example, the terminal device may detect which of the tee positions includes the user's position, and then take the tee including the user's position as the target tee.

S304, according to the information of the inflection point corresponding to the target billiard table, displaying the inflection point and the distance between the user and the green in the golf course map.

After the terminal device acquires the map data, a golf course map may be displayed on the terminal device. For example, referring to a in fig. 5, the terminal device may display a partial map around the location of the user in the golf course according to the location of the user, and display the location of the user, such as location a, in the map. Fig. 5 is a partial view of the tee box, the fairway, and the green shown in fig. 1.

In the embodiment of the application, because the terminal equipment can acquire the information of the inflection points corresponding to the plurality of tee boxes in the golf course in advance, the terminal equipment can acquire the information of the inflection points corresponding to the target tee box in the information of the inflection points corresponding to the plurality of tee boxes. The location of the inflection point may be included in the information of the inflection point corresponding to the target tee, so the terminal device may display the inflection point in the golf course map. Referring to a in fig. 5, the terminal device may display an inflection point, such as position B, in the golf course map.

In one example, when positions of a plurality of inflection points are included in the information of the inflection point corresponding to the target tee, referring to B in fig. 5, the terminal device may display the plurality of inflection points, such as position B and position C, in the golf course map. In one example, when an inflection point range is included in the information of the inflection point corresponding to the target tee, referring to c in fig. 5, the terminal device may display the inflection point range, such as a gray circle covered range, in the golf course map.

It should be understood that the purpose of the terminal device displaying the inflection point in the golf course map is to: the golf ball falling point is recommended to the user, and the user can adjust the hitting force, the hitting direction and the like according to the position of the inflection point, so that the golf ball can fall on the inflection point.

In one embodiment, after determining the inflection point information corresponding to the billiard table, the terminal device may further determine a distance between the billiard table and the green according to the inflection point information. Taking a billiard table as an example, the terminal device may determine a first line segment and a second line segment with the largest included angle according to inflection point information corresponding to the billiard table, and sum the lengths of the first line segment and the second line segment to be the distance between the billiard table and the green. Correspondingly, the terminal device can acquire the distance between the target billiard table and the green, namely the distance between the user and the green.

In such an embodiment, referring to a in fig. 5, the terminal device may also display the distance of the target tee from the green, i.e., the distance of the user from the green. Illustratively, a in fig. 5 represents the distance between the user and the green by circles of different radii centered around the center point of the green.

In such an embodiment, referring to a in fig. 5, the terminal device may also display the distance of the user from the inflection point, i.e. the length of the first line segment. By way of example, a in fig. 5 may represent the distance of the user from the inflection point in circles of different radii centered around the user's location. The terminal device can use the distance between the inflection point with the largest included angle and the user as the distance between the user and the inflection point. Or the information of the inflection point corresponding to the target billiard table comprises an inflection point range, and the terminal equipment can use the distance between the center point of the inflection point range and the user as the distance between the user and the inflection point.

In one embodiment, after determining the target billiard table, the terminal device may further obtain an angle of the inflection point corresponding to the target billiard table relative to the user according to inflection point information corresponding to the target billiard table and the position of the user. In an exemplary embodiment, the terminal device may obtain, in inflection point information corresponding to the target billiard table, an angle of the inflection point with respect to the user according to a position of the inflection point where an included angle between the first line segment and the second line segment is the largest and a position of the user. For example, when the information of the inflection point corresponding to the target billiard table includes an inflection point range, the terminal device may obtain the angle of the center point of the inflection point range relative to the user according to the position of the center point of the inflection point range and the position of the user.

Referring to fig. 6, the terminal device may display an angle of the inflection point with respect to the user in the golf course map. Illustratively, the angle of the inflection point relative to the user is characterized by an arrow and an orientation "such as 10 ° in the northwest direction" in fig. 6.

In one embodiment, referring to fig. 5 and 6, the terminal device may also display the number of doglegs, as well as the standard number of poles. For example, the dogleg hole is hole No.2 (indicated by H02 in FIG. 5), and the standard number of rods is 5 rods (indicated by Par5 in FIG. 5).

In the embodiment of the application, the terminal equipment can determine the inflection point in the lane according to the map data, and further calculate the distance between the user and the green according to the inflection point. In addition, the terminal equipment can display inflection points and the distance between the user and the green in the golf course map, so that the user can be assisted in batting more accurately, and the user experience is improved.

In the above embodiment, when the user hits the first driver or when the user's position is in the tee, the terminal device may acquire information of the inflection point and the positions of the user and the green according to the embodiment shown in fig. 3. In one possible scenario, for example, after the user hits the ball, the drop point of the golf ball is not included in the tee, and when the user hits the ball again, because the position of the user is not in the tee, the terminal device cannot acquire the inflection point information in the inflection point information corresponding to the existing tee, and cannot display the inflection point. For example, referring to fig. 7, the user hits a ball at the tee 1, the drop point of the golf ball is at the position D, and when the user hits the ball at the position D, the user's position is not at the tee, and the terminal device cannot acquire information of the inflection point nor display the inflection point.

In one embodiment, the terminal device may obtain the information of the inflection point according to the location of the user. In this way, even if the user's location is not included in the tee, the terminal device can acquire information of the inflection point and display the inflection point and the green distance.

Referring to fig. 8, the method for determining a distance in a golf course according to an embodiment of the present application may include:

S801, a position of a user is acquired.

S801 may refer to the related description of S302. In one example, referring to the description related to S302, after the terminal device obtains the position of the user, it may detect whether the position of the user is included in the hole contour of the target hole, if the position of the user is included in the hole contour of the target hole, the terminal device may perform S802-S803, if the position of the user is not included in the hole contour of the target hole, which indicates that the user may have deviated from the hole contour of the target hole, the terminal device may not perform S802-S803.

In the embodiment of the application, the terminal equipment can acquire the information of the inflection point in the position contained in the map data. The terminal device may acquire the candidate inflection point in a location included in the map data, and further determine the inflection point according to the candidate inflection point. In one example, the candidate inflection point needs to satisfy the following condition:

Condition 1: is within the lane contour.

Condition 2: on the centerline.

Condition 3: the linear distance from the center point of the green is greater than a first threshold value.

Condition 5: and connecting the first line segment with the central point of the green to obtain a third line segment, and connecting the first line segment with the position of the user to obtain a third line segment, wherein the included angle between the first line segment and the third line segment is in a preset angle range.

Unlike the above condition 4, the angle between the first line segment and the third line segment, which is a line connected to the position of the user, is obtained in the condition 5. In such an embodiment, the distance of the user from the green is the sum of the lengths of the first and third line segments. The terminal device may screen to obtain candidate inflection points according to the above 4 conditions, and the embodiment of the present application does not limit the order in which the terminal device uses the above 4 conditions, and may refer to the related description in S301.

In one embodiment, the terminal device may obtain information of the inflection point upon determining that the user's location has not passed beyond the start of the lane. It will be appreciated that the purpose of this arrangement is to: if the position of the user has crossed the starting point of the lane, the user can see the green with high probability, so that the user can adjust the batting strength, batting angle and the like by virtue of own experience without displaying an inflection point.

The lane start point can be understood as: the intersection point of the lane outline and the center line is an intersection point far away from the green direction. Illustratively, referring to FIG. 1, the intersection of the lane contour with the centerline is intersection a and intersection b, which may be the lane start point. In this embodiment, the terminal device may obtain the distance between the user and the green according to the position of the user and the position of the center point of the green, and may obtain the distance between the lane start point and the green according to the position of the lane start point and the position of the center point of the green. The terminal equipment responds that the distance between the lane starting point and the green is smaller than or equal to the distance between the user and the green, and can acquire the information of the inflection point, and the terminal equipment responds that the distance between the lane starting point and the green is larger than the distance between the user and the green, and does not need to acquire the information of the inflection point.

S803, displaying the inflection point and the distance between the user and the green in the golf course map according to the information of the inflection point.

S803 can refer to the related description of S304.

Referring to fig. 7, when the user is at the location D and the location D is not included in the tee, the terminal device may perform S802 to obtain information of the inflection point, and further the terminal device may display the inflection point and the distance of the user from the green in the golf course map.

In one embodiment, fig. 9A shows a flow chart of a method for determining a distance in a golf course performed by a terminal device. Referring to fig. 9A, the terminal device may download map data of a golf course, and extract data required for the terminal device in the map data of the golf course, for example, may include a green contour, a center point position of the green, a tee position, a center point position of the tee, a hole contour, a lane contour, and a center line coordinate, etc. The terminal device can filter out invalid points according to the conditions required to be met by the inflection points, wherein the invalid points are points which are not candidate inflection points. The terminal device may connect the candidate inflection point with the center point of the user and the green to obtain a first line segment, and connect the candidate inflection point with the tee to obtain a second line segment (or connect the candidate inflection point with the user to obtain a third line segment), and calculate an included angle between the first line segment and the second line segment (or calculate an included angle between the first line segment and the third line segment). The terminal device may use the candidate inflection point corresponding to the maximum included angle as the inflection point of the lane.

In the embodiment of the application, the terminal equipment can acquire the information of the inflection point according to the position of the user, so that even if the position of the user is not contained in the service platform, the terminal equipment can acquire the information of the inflection point, the accuracy of the inflection point can be ensured, and the accurate inflection point can be displayed for the user.

In the embodiments shown in fig. 3 and 8, in one example, the terminal device may periodically obtain the location of the user, and may then periodically update the display inflection point, and the distance between the user and the green.

In one example, the terminal device may determine a period for acquiring the position of the user according to the state of the terminal device, so as to adaptively adjust the calculation amount of the terminal device and reduce the power consumption of the terminal device.

The states of the terminal device include a bright screen state and a dark screen state, when the terminal device is in the bright screen state, the position of the user is obtained once every first time period, when the terminal device is in the dark screen state, the position of the user is obtained once every second time period, and the second time period is longer than the first time period. When the terminal equipment is in a bright screen state, for example, the terminal equipment can acquire the position of the user every 1s, so that the terminal equipment updates the inflection point every 1s and the distance between the user and the green. When the terminal equipment is in the screen-off state, the map representing that the user is not looking at the golf course is displayed, for example, the terminal equipment can acquire the position of the user every 1min, so that the terminal equipment updates the inflection point every 1min and the distance between the user and the green.

Referring to a in fig. 9B, when the terminal device is in a bright screen state, the terminal device may update the inflection point and the distance of the user from the green every 1 s. Referring to B in fig. 9B, when the terminal device is in the off-screen state, the terminal device may update the inflection point and the distance between the user and the green every 1min, and B in fig. 9B does not show the interface of the terminal device because the terminal device is in the off-screen state.

In one example, the state of the terminal device may characterize the user's motion state, and the terminal device may, illustratively, obtain a change in the pose of the terminal device from the sensor 250 in the terminal device, and thereby determine the user's motion state. Wherein if the user's motion state is moving, it can be characterized that the user is not batting, the terminal device can increase the period of acquiring the user's position, or the terminal device does not acquire the user's position while the user is moving. When the motion state of the user is static, if the position of the user is unchanged within a preset duration, the user is characterized that the user is likely to hit the ball with high probability, and the terminal equipment can reduce the period of acquiring the position of the user and timely display the inflection point and the distance between the user and the green.

Thus, the terminal device can adaptively adjust the calculation period according to the state of the terminal device, and the power consumption of the terminal device can be reduced.

In one example, to reduce the workload of the terminal device, reduce the power consumption of the terminal device, the terminal device may display a key to suspend positioning, and the user may trigger the terminal device to suspend acquiring the position of the user, and further suspend executing the action of acquiring the information of the inflection point, and displaying the distance between the inflection point and the user and the green. For example, the user may move to the golf ball drop point after the ball is hit by the tee, and power consumption of the terminal device may be consumed if the terminal device always calculates the position of the user, information of inflection points, and the like during the movement of the user. In the embodiment of the application, after the user hits the ball on the service table, the user can operate the pause positioning key to trigger the terminal equipment to pause the acquisition of the position of the user, and when the user moves to the drop point of the golf ball, the user can operate the pause positioning key again to trigger the terminal equipment to acquire the position of the user, so that the terminal equipment does not need to acquire the position of the user in the process of moving the user to the drop point of the golf ball, and the calculation amount and the power consumption of the terminal equipment can be reduced.
