Based on the above description, an embodiment of the present application provides a navigation data processing method. Referring to fig. 2, fig. 2 is a schematic flow chart of a navigation data processing method according to an embodiment of the present disclosure. The execution main body in the embodiment of the present application may be an electronic device, and the electronic device may be a terminal device, a server, or a server and a terminal device. As shown in fig. 2, the navigation data processing method may include steps S201 to S203.

Step S201, acquiring navigation data of a driving object, and determining a curve road section in a navigation map according to the navigation data.

In this application, the navigation data may refer to related route data of a navigation route between a departure location and a destination location, and the navigation route may have a plurality of location points, for example, one location point every 10 meters. The navigation map is used to present a navigation route for navigation to a user, the navigation route being generated from navigation data. In other words, the navigation route set by the user can be visualized through the navigation map to show the navigation route to the user for viewing.

The departure location and the destination location may be set by a user through a navigation client, or the location of the driving object may be determined as the departure location, and then the destination location is set through the navigation client, which is not limited herein. Optionally, the navigation data may further include related information near the navigation route between the departure location and the destination location, such as store information, road name information, traffic identification information, speed measurement camera information, violation snapshot camera information, and the like, which is convenient for the traveling object to travel, and this is not limited herein. The traveling object may be any type of vehicle, such as an unmanned vehicle, a battery car, a bicycle, a car, a bicycle, etc., or may be a pedestrian, which is not limited herein. The curve road section is a road section which meets the conditions of curve radius, curve steering angle and curve arc length in a navigation route.

In one possible embodiment, determining a curve section in the navigation map from the navigation data may comprise the following steps: detecting a road section starting position and a road section ending position of a road section of a curve to be determined in navigation data; according to the road section data between the road section starting position and the road section ending position of the road section of the curve to be determined in the navigation data, determining the radius of the curve to which the road section of the curve to be determined belongs, the steering angle of the curve and the arc length of the curve; and when the radius of the curve to which the curve section to be determined belongs is less than or equal to a first curve radius threshold value, the steering angle of the curve to which the curve section to be determined belongs is greater than a steering angle threshold value, and the arc length of the curve to which the curve section to be determined belongs is greater than an arc length threshold value, determining the curve section to be determined as the curve section. The road section data comprises a navigation route between a road section starting position and a road section ending position of a road section of the curve to be determined, and data such as the radius of the curve at each position point in the road section, the arc length of the curve in the road section, the steering angle of the curve in the road section and the like. The curve radius of the curve section to be determined corresponds to the curvature radius of the mathematical curve, which curve section to be determined can be regarded as a mathematical curve. As can be seen from the mathematical law, the radius of curvature is the inverse of the curvature, and the curvature is used to indicate the degree of curvature of the curve, and the smaller the radius of curvature, the larger the degree of curvature of the curve. The curve turning angle refers to an angle between a tangent direction of a road section starting position of a curve section to be determined and a tangent direction of a road section ending position, the tangent direction refers to a direction along a navigation route on a tangent line corresponding to a position in the curve section to be determined, the tangent line is equivalent to a tangent line of a certain point on a curve of a mathematical angle, the curve section to be determined can be regarded as a mathematical curve, the unit of the curve turning angle can be an angle unit such as degree, minute or second, and the like, and the limitation is not made here. The curve arc length refers to a total length of the road section between the starting position and the ending position of the road section of the curve road section to be determined (for example, the curve road section to be determined can be regarded as a curve, and the total length of the curve road section to be determined is also the total length of the curve), and the unit of the curve arc length can be a unit with equal distance of m, km or kilometer, which is not limited herein. The first curve radius threshold value may also be referred to as a maximum curve radius required for determining the curve section to be determined as the curve section. The steering angle threshold value may also be referred to as a minimum value of the steering angle required for determining the curve section to be determined as the curve section. The arc length threshold may also be the minimum value of the arc length required to determine the curve section to be determined as the curve section. Optionally, the first curve radius threshold, the steering angle threshold, and the arc length threshold may all be set via a cloud server.

In one possible embodiment, the segment start position and the segment end position for detecting the curve segment to be determined may be determined based on a steering angle between each position point in the segment data between the origin position and the destination position indicated by the navigation data. Specifically, a plurality of positions are sampled on a navigation route in sequence according to sampling distances, so that a plurality of sampling positions are obtained, wherein the sampling distances refer to the lengths of road sections between adjacent sampling positions; acquiring a tangential direction of each sampling position, then traversing each sampling position, and calculating a steering angle between each sampling position and each sampling position after the sampling position, for example, detecting a steering angle between a target sampling position and each position after the target sampling position, where the steering angle may include a first steering angle between a first sampling position and the target sampling position, and a second steering angle between a second sampling position and the target sampling position, where the first sampling position is before the second sampling position, and if the first steering angle is the same as the second steering angle, taking the target sampling position as a section start position of a section of a curve to be determined, and determining a section end position of the section of the curve using the first steering position. Then, the next sampling position of the target sampling position is operated as above, so that one or more curve sections to be determined can be obtained.

In one possible embodiment, the section start position and the section end position of the detected curve section to be determined can also be determined as a function of the curve radius between each position in the section data between the origin position and the destination position indicated by the navigation data. Specifically, a plurality of positions are sequentially sampled on the navigation route according to a sampling distance, so as to obtain a plurality of sampling positions, wherein the sampling distance refers to the length of a road section between adjacent sampling positions, and for example, a position is obtained by sampling every 10 meters. More, the curve radius of each sampling position may also be obtained, a sampling position where the curve radius is less than or equal to the first curve radius threshold is determined from the curve radius, and the navigation route corresponding to the sampling positions where the successive curve radii are less than or equal to the first curve radius threshold is used as a curve segment to be confirmed, then in the curve segment to be confirmed, the most front sampling position (for example, the first sampling position) is the segment start position of the curve segment to be confirmed, the most rear sampling position (for example, the last sampling position) is the segment start position of the curve segment to be confirmed, and the front sampling position and the rear sampling position are described with respect to the direction of the navigation route.

For ease of understanding the determination of the curve section, different navigation routes are explained here as examples. Referring to fig. 3a, fig. 3a is a schematic diagram illustrating an effect of a curve section according to an embodiment of the present application, in the curve section, a length of the section between a section start position a and a section end position b is a curve arc length, a radius of the curve is less than or equal to a first curve radius threshold, a steering angle of the curve is greater than a steering angle threshold, and the curve arc length is greater than an arc length threshold. Referring to fig. 3b, fig. 3a is a schematic diagram of an effect of a curve segment according to an embodiment of the present disclosure, where a position point d is both a segment start position of one curve segment and a segment end position of another curve segment, a segment length between a segment start position c and the position point d is a curve arc length 1, a segment length between the position point d and the segment end position e is a curve arc length 2, and segment start positions of the two curve segments are connected to the segment end position, but both of the two curve segments satisfy a condition that a curve radius of the curve segment is smaller than or equal to a first curve radius threshold, a steering angle of the curve segment is greater than a steering angle threshold, and a curve arc length of the curve segment is greater than an arc length threshold. Referring to fig. 3c, fig. 3c is a schematic diagram illustrating an effect of a non-curved road segment according to an embodiment of the present application, where the non-curved road segment is a road segment similar to a quarter turn, and a curve arc length of the non-curved road segment is a road segment length between a road segment start position f and a road segment end position g, but the non-curved road segment is not a curved road segment, because only a curve radius of the quarter turn of the non-curved road segment satisfies a condition, that is, is smaller than a first curve radius threshold, but the curve arc length does not satisfy the condition, that is, is smaller than a curve arc length threshold, the non-curved road segment is not a curved road segment. Referring to fig. 3d, fig. 3d is a schematic diagram illustrating an effect of a non-curved road segment according to an embodiment of the present application, the non-curved road segment is a non-curved road segment similar to a quarter turn, the distance between the two non-curved road segments is a certain road segment length d, for the reason described with reference to fig. 3c, the arc length of the two quarter turn road segments of the non-curved road segment does not satisfy the condition, that is, is less than the arc length threshold, and the non-curved road segment is not a curved road segment.

In step S202, when it is detected that the object position of the traveling object is in a target section indicated by a curve section, a scaling of the navigation map is determined according to curve attribute information associated with the curve section.

The target road section of the object position may refer to the road section of the driving object in the curve, the road section of the driving object in the curve road section before the road section start position, or the road section of the driving object in the curve road section after the road section end position. The curve-in mileage threshold value is a maximum value of the mileage of a road segment before the start position of the road segment of the curve road segment when the road segment is a part of the target road segment, and the curve-out mileage threshold value is a maximum value of the mileage of a road segment after the end position of the road segment of the curve road segment when the road segment is a part of the target road segment. In other words, the target road segment may include a curve road segment, or the target road segment may include a road segment indicated by a mileage-in-curve threshold and a curve road segment, or the target road segment may include a road segment indicated by a mileage-in-curve threshold, a road segment indicated by a mileage-out-of-curve threshold and a curve road segment.

For example, referring to fig. 4a, fig. 4a is a schematic diagram illustrating an effect of a target road segment according to an embodiment of the present application, where the target road segment indicated by the curve road segment includes a curve road segment, and the target road segment indicated by the curve road segment is a road segment between a road segment start position l of the curve road segment and a road segment end position m of the curve road segment. Referring to fig. 4b, fig. 4b is a schematic diagram illustrating an effect of a target road segment according to an embodiment of the present application, where the target road segment indicated by the curve road segment includes a road segment indicated by a mileage-in-curve threshold and a curve road segment, and then the road segment indicated by the mileage-in-curve threshold is a road segment between a position n and a start position p of the curve road segment, where the position n may be referred to as a mileage-in-curve position, and then the target road segment indicated by the curve road segment is a road segment between the mileage-in-curve position n and a start position q of the curve road segment. Referring to fig. 4c, fig. 4c is a schematic diagram illustrating an effect of a target road segment according to an embodiment of the present application, where the target road segment indicated by the curve road segment includes a road segment indicated by a mileage-in threshold, a road segment indicated by a mileage-out threshold, and a curve road segment, the road segment indicated by the mileage-in threshold is a road segment between a position r and a start position s of the curve road segment, the road segment indicated by the mileage-out threshold is a road segment between a road segment end position t and a position u of the curve road segment, the position may be referred to as a curve-in position, the position u may be referred to as a curve-out position, and the road segment indicated by the curve-in position r and the curve-out position u are located between the curve-in position t and the curve-.

The curve attribute information may include information such as a curve radius, a curve steering angle, a curve arc length, etc. of the curve section. The scaling ratio can be expressed as a ratio of 1 pixel of the display screen of the electronic device to the actual distance, for example, if the scaling ratio is 20m, then 1 pixel of the display screen of the electronic device corresponds to 20m of the actual distance, and the scaling ratio can also be expressed as a ratio of 1mm on the display screen of the electronic device to the actual distance, for example, if the scaling ratio is 5m, then 1mm on the display screen of the display terminal corresponds to 5m of the actual distance, and the representation manner for the scaling ratio is not limited herein.

In one possible embodiment, when the object position is in the target road segment and the traveling object is in the curve road segment, it may be determined whether the object position is in the target road segment by detecting whether the object position is in the road segment between the road segment start position and the road segment end position of the curve road segment, that is, when the object position is in the road segment between the road segment start position and the road segment end position of the curve road segment, it indicates that the object position is in the target road segment, and when the object position is not in the road segment between the road segment start position and the road segment end position of the curve road segment, it indicates that the object position is not in the target road segment. Alternatively, in an actual navigation scenario, the object position of the traveling object may generally go from far to near to the starting position of the road section of the curve road section, so as to enter the curve road section, and then the scaling of the navigation map may be determined according to the curve attribute information associated with the curve road section when it is detected that the object position enters the curve road section through the starting position of the road section.

In one possible embodiment, detecting that the object position is on the target road segment indicated by the curved road segment when the object position is on the target road segment indication and the object position is on a road segment indicated by the curved road segment trip mileage threshold before the road segment start position may include the steps of: determining the driving mileage between the position of the object and the initial position of the road section of the curve road section to obtain the curve-entering driving mileage; and when the bend-in driving mileage is detected to be smaller than the bend-in driving mileage threshold value, determining that the position of the object is in the target road section. The bend-in driving range refers to the length of the road section between the position of the object and the starting position of the road section before the starting position of the road section of the curve road section. Referring to fig. 5, fig. 5 is a schematic diagram illustrating an effect of a target road segment provided in an embodiment of the present application, where the curved-in driving range is a length of the road segment between an object position Z and a starting position p of the road segment of the driving object, and the curved-in driving range threshold is a length of the road segment between a curved-in position n and the starting position p of the road segment, and the curved-in driving range is smaller than the curved-in driving range threshold, then the driving object is located on the target road segment. Alternatively, in an actual navigation scenario, the object position of the traveling object may generally be driven from far to near to the starting position of the road section of the curve road section, so as to enter the curve road section, and then the scaling of the navigation map may be determined according to the curve attribute information associated with the curve road section when the object position is detected to pass through the curve entering position.

In one possible implementation, determining the scale of the navigation map based on the curve attribute information associated with the curve segment may include: when the curve radius of the curve road section is smaller than or equal to a second curve radius threshold, determining the scaling as a first scaling; and when the curve radius of the curve road section is larger than the second curve radius threshold and is smaller than or equal to the first curve radius threshold, determining a scaling ratio from the scaling interval according to the numerical value of the curve radius of the curve road section. The second curve radius threshold is smaller than the first curve radius threshold, the zooming interval is composed of a first zooming proportion and a second zooming proportion, and the second zooming proportion is larger than the first zooming proportion. Specifically, reference may be made to fig. 6, where fig. 6 is a schematic diagram of a relationship between a scaling ratio and a radius of a curve provided in an embodiment of the present application, and is expressed by a rectangular coordinate system, where an abscissa represents the radius of the curve and an ordinate represents the scaling ratio. For example, the first curve radius threshold is 150m, the second curve radius threshold is 50m, the first scaling is 10m, the second scaling is 20m, the scaling interval is 10m-20m, the scaling is 20m when the curve radius of the curve section is 150m, the scaling is 10m when the curve radius of the curve section is 50m or less, the scaling varies linearly with the curve radius of the curve section when the curve radius of the curve section is 50 m-150 m, in other words, the scaling varies linearly with the curve radius of the curve section between 10m-20m scaling intervals, such as 15m when the curve radius is 100m, and the scaling is 16m when the curve radius is 120 m.

And S203, zooming the navigation map based on the zooming scale to obtain a zooming map.

The zoom map always keeps the zoom scale when the object position is in a target road section indicated by the curve road section, the zoom map comprises road section key positions of the curve road section visualization, and the road section key positions comprise key positions of a road section starting position, a road section ending position, an arc length vertex position of the curve and the like. The visualized key position of the road section refers to a key position of the road section of the curve road section which can be displayed in a visualized area of the navigation interface, in other words, the visualized area can completely display the key position of the road section of the curve road section. Alternatively, boundary points of the curve segment may be determined, and the segment key locations may be visualized by enabling the boundary points to be visualized in the navigation interface, where the boundary points may include an upper boundary point, a lower boundary point, a left boundary point, and a right boundary point, respectively for representing the uppermost, lowermost, leftmost, and rightmost locations of the curve segment in the visualization area.

In one possible embodiment, a zoom map is displayed on the navigation interface when the object position of the driving object is detected to be in the target road section. The navigation interface can be used for displaying a navigation map and/or a zoom map and the like. The zooming map displayed by the navigation interface comprises the road section key positions of the curve road section visualization, and the zooming map always keeps the same zooming scale until the driving object drives out of the target road section indicated by the curve road section. For example, referring to fig. 7, fig. 7 is a schematic effect diagram of a client navigation interface provided in an embodiment of the present application, where the client navigation interface may include a visualization area, and the visualization area is used to display a navigation map and/or a zoom map, where before zooming the navigation map, the visualization area of the navigation interface is used to display the navigation map, and the navigation interface is shown in the schematic effect diagram in fig. 7 before zooming. After the navigation map is zoomed, the visualized area of the navigation interface is used for displaying the zoomed map, as shown in the zoomed effect schematic diagram in fig. 7, the position of each road section key and each boundary point of the curve road section can be completely displayed in the navigation interface for displaying the zoomed map, the leftmost position of the curve road section corresponds to the left boundary point, the rightmost position of the curve road section corresponds to the right boundary point, and the uppermost position of the curve road section corresponds to the upper boundary point, so that the left boundary point, the right boundary point and the upper boundary point can be visualized in the navigation interface for displaying the zoomed map. Optionally, the navigation interface displaying the zoom map may completely display the key position of the target road segment indicated by the curved road segment and each boundary point of the target road segment, that is, the zoom map includes the key position of the road segment visualized by the target road segment indicated by the curved road segment, and the key position of the road segment includes key positions such as the bend-in position of the target road segment, the bend-out position of the target road segment, and the arc length vertex position of the curved road segment. Obviously, navigating through the zoomed navigation interface can enable a user to judge the road condition of the current curve road section more clearly, and the user does not exit the navigation interface for displaying the zoomed map until the user exits that the driving object completely passes through the curve road section.

In a possible implementation, zooming the navigation map based on the zoom scale to obtain the zoom map may include the following steps: zooming the navigation map based on the zooming scale to obtain a transitional zooming map; and determining a target map view in the transitional zoom map according to the key position of the road section of the curve road section, and determining the transitional zoom map containing the visual target map view as the zoom map. The target map view field comprises visualized key positions of the road section, and the key positions of the road section can comprise key positions of a road section starting position, a road section ending position, an arc length vertex position of the curve, a bend-in position of the target road section, a bend-out position of the target road section and the like. The transitional zoom map is a map only zoomed on the navigation map, but in the transitional zoom map, the key position of the road section of the target map may not be completely displayed, and the view field of the target map is determined according to the key position of the road section, and the transitional zoom map is adjusted, so that the view field of the target map in the transitional zoom map can be completely displayed on the visual area of the navigation interface of the electronic device, namely the visual view field of the target map.

In one possible implementation, before the large-scale map is zoomed based on the zoom scale, the curve prompt information can be obtained and is broadcasted in voice, so that the user can know the information of the curve ahead. Specifically, the arc length of the curve is determined as the curve driving mileage of the curve road section, the curve distortion degree of the curve road section is determined according to the curve steering angle, curve prompt information is generated according to the curve driving mileage, the curve distortion degree and the curve entering driving mileage, and voice broadcasting prompt is carried out on the curve prompt information. The curve mileage refers to a mileage value required for the traveling object to completely pass through the curve section. This bend distortion journey can describe through the distortion grade, if slight distortion, moderate distortion or severe distortion etc. bend steering angle usually, bend steering angle is big more, and then bend distortion degree is high more to probably the bend is dangerous more, so through voice broadcast, the distortion degree of suggestion driving object preceding bend, thereby makes driving object improve vigilance, safe driving. The curve-entering driving range refers to a range value between the position of the object and the starting position of the road section before the starting position of the road section of the curve road section, and when the driving object is at the road section indicated by the curve-entering driving range threshold value, the driving object is prompted to see how many ranges are about to be carried out on the curve road section, so that a user knows that the front is the curve road section in advance and pays attention to safe driving.

Fig. 8 is a schematic flow chart illustrating a navigation data processing method according to an embodiment of the present invention. The navigation data processing method may be performed by an electronic device. As shown in fig. 8, the navigation data processing method may include the following steps S801 to S805.

And step S801, acquiring navigation data of the driving object, and determining a curve road section in the navigation map according to the navigation data.

Step S802, when it is detected that the object position of the traveling object is in a target section indicated by a curve section, determines a scaling of the navigation map according to curve attribute information associated with the curve section.

And S803, zooming the navigation map based on the zooming scale to obtain the zooming map.

For a specific implementation manner of the steps S801 to S803, reference may be made to the specific description of the steps S201 to S203 in the embodiment corresponding to fig. 2, and details are not repeated here.

Step S804 acquires the travel position of the travel object.

The time of the travel position is later than the time of the object position, that is, when the travel object indicates the navigation route to travel according to the navigation data, the travel object passes through the object position and then passes through the travel position. Obviously, the driving position and the object position do not specifically refer to a certain position point in the navigation route, but are used for representing the precedence relationship of the time of the two positions, and in an actual scene, the object position and the driving position may refer to any position in the navigation route, but the time of the driving position is always later than the time of the object position.

And step S805, when the driving position is detected to be at the road section end position of the curve road section, restoring the zoom map according to the zoom ratio to obtain a restored map.

And the map display scale of the reduction map is equal to the map display scale of the navigation map. The display scale may be represented as a ratio of 1 pixel of a display screen of the electronic device to an actual distance, for example, if the display scale is 20m, then 1 pixel of the display screen of the electronic device is equivalent to 20m of the actual distance, and the display scale may also be represented as a ratio of 1mm of the display screen of the electronic device to the actual distance, for example, if the scaling scale is 5m, then 1mm of the display screen of the display end is equivalent to 5m of the actual distance, and the representation manner of the scaling is not limited herein. The mm and m are both distance units. It is detected that the driving position is at a link end position of the curve link, in other words, the link end position where the driving object passes through the curve link while the driving object is traveling in accordance with the navigation data. Optionally, when the driving position is detected to be at the curve exit position after the road section end position of the curve road section, the zoom map may be restored according to the zoom ratio to obtain the restored map.

In one possible implementation, the zoom map may be restored according to a ratio of a zoom scale of the zoom map to a display scale of the navigation map. For example, if the zoom scale of the zoom map is 20m and the display scale of the navigation map is 50m, and the ratio between the zoom scale of the zoom map and the display scale of the navigation map is 2/5, when it is detected that the travel position is at the link end position of the curved link, the display scale of the restored map is 50m according to the ratio between the zoom scale of the zoom map and the display scale of the navigation map.

In one possible embodiment, when it is detected that the driving position is at the section end position of the curve section, curve exit prompt information can also be acquired, and the curve exit prompt information is subjected to voice broadcast. Specifically, when it is detected that the traveling object is at the section end position of the curve section, it may be prompted that the traveling object has exited the current curve section, so as to prompt the user that the current navigation map is not the zoom map.

In one possible embodiment, when the object position of the driving object is detected to be in the target road section, a zoom map is displayed on the navigation interface; and when the driving position is detected to be at the road section end position of the curve road section, switching and displaying the zoom map displayed on the navigation interface into a reduction map. The navigation interface is used for displaying a navigation map, a zoom map and/or a reduction map. Optionally, the navigation interface may further include a visualization area, and the visualization area is used for displaying a navigation map, a zoom map and/or a reduction map. Referring to fig. 9a, fig. 9a is a schematic view of a navigation process provided in an embodiment of the present application, before entering a curve segment, when it is detected that a distance from a driving object to a starting position of the segment is a threshold of a driving mileage for bending, that is, when the driving object passes through a position for bending, a navigation map is zoomed, the driving object drives on the curve segment according to the zoomed navigation map, when it is detected that the driving object passes through a segment ending position of the curve segment, zooming of the navigation map is stopped, a display scale of the navigation map is restored, then it is detected whether to enter a next curve segment, and when it is detected that the driving object is about to enter the next curve segment, the above steps are repeated until the driving object completely passes through the navigation route. In the navigation process shown in fig. 9a, please refer to fig. 9b for an effect display interface of the navigation interface, and fig. 9b is a schematic view of an effect of the navigation interface provided in the embodiment of the present application. Before the driving object enters the target road section indicated by the curved road section, the navigation is performed according to the navigation interface of the navigation map before zooming shown in fig. 9b, and in the navigation interface, the map display scale of the navigation route is large, so that the road condition of the curved road section to which the driving object is about to enter cannot be clearly displayed. When the driving object is detected to pass through the bend-entering position, zooming the navigation map to obtain a zoom map, and navigating according to the navigation interface for displaying the zoom map shown in fig. 9b, namely when the driving object is located at the target road section indicated by the bend road section, navigating according to the navigation interface for displaying the zoom map shown in fig. 9b, wherein in the navigation interface, the navigation interface can clearly display the road condition of the bend road section which the driving object is about to enter. When it is detected that the driving position of the driving object moves out of the section end position of the curved road section, the zoomed map is restored to obtain a restored map, navigation is performed according to the navigation interface which is shown in fig. 9b and displays the restored map, in the navigation interface, the display scale of the map is consistent with the display scale of the navigation map before zooming, and when a target section indicated by the next curved road section is detected, the steps are repeated until the driving object completely passes through the navigation route.

In a possible embodiment, if there is a portion of overlap between the target links indicated by the consecutive curved road segments, and the driving object is detected to be at the curve-out position of the previous target link, the next target link is directly switched to the zoom map corresponding to the next target link, and the zoom ratio of the next zoom map and the previous zoom map may be the same or different, and this is determined according to the actual situation. For example, if there is an overlap between the target link 1 and the target link 2, in other words, the bend-in position of the target link 2 is located before the bend-out position of the target link 1, when it is detected that the driving position of the driving object is at the bend-out position of the target link 1, the zoom scale of the zoom map is switched to the zoom scale corresponding to the target link 2, and the zoom map corresponding to the target link 1 displayed on the navigation interface is switched to the zoom map corresponding to the target link 2.
