[0014] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the accompanying drawings show exemplary embodiments of the present disclosure, the present disclosure can be implemented in various forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to enable a deeper understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0015] In general 3D map display control, after two-finger interaction locks one type of interaction, other viewpoint changes cannot be performed at the same time, for example, only zooming in and out and / or horizontal rotation, zooming in and / or vertical rotation, etc. can be performed, and when it is necessary to switch to another interaction method, it is necessary to operate again after removing two fingers from the screen, which makes the map display interaction operation complicated. An embodiment of the present disclosure provides a map display adjustment method, and as shown in FIG. 1, the method includes the following steps:

[0016] In step 101, when a map display page adjustment command is received, adjustment gesture data is obtained.

[0017] Here, the adjustment command is transmitted by a user operating a touch display on the map display page, and the adjustment gesture data includes at least an adjustment start finger position and an adjustment end finger position. The touch display may be disposed on a mobile terminal device, a site guide device, a mobile robot, etc., and the adjustment finger position is determined according to a finger touch point in the coordinate system by establishing a coordinate system in the plane of the touch display, specifically, the adjustment finger position may be obtained by invoking a preset interface or a preset algorithm when a finger touches the touch display, and is not particularly limited in the embodiment of the present application.

[0018] In the embodiment of the present application, the map display page adjustment command may be sent when the user's finger presses the touch display for a short time. For example, when the user's finger stays on the mobile phone screen for 0.2 seconds and then moves, it can be determined that the current user operation indicates that the map display page is to be adjusted, and the sending of the map display page adjustment command to the server side is triggered so that the server adjusts the map display page according to the user's operation.

[0019] In addition, the terminal device can download a corresponding map application program via the Internet in advance, load map data and store it locally or in the cloud, and adjust and display the map display page according to user operations during use.

[0020] In step 102, the adjustment gesture data is analyzed to obtain an adjustment indicator.

[0021] Here, the adjustment indicator is for identifying the position change of the adjustment gesture in the process of adjusting the current map display. Specifically, the adjustment indicator may be the distance between fingers, the position change of a certain reference point, for example, the midpoint of the line connecting the positions of two fingers, the position change of fingers on a touch display, etc., and is not particularly limited in the embodiments of the present application.

[0022] In an embodiment of the present application, by analyzing the data generated when a user adjusts a map display page, data capable of identifying a position change of the adjustment gesture can be obtained. For example, based on the adjustment gesture data, if the adjustment gesture is identified as finger 1 moving from a1 to a2 and finger 2 moving from b1 to b2, the two sets of finger data may be used as the adjustment index in this step.

[0023] In step 103, the map display page is scaled according to the adjustment indicator and rotated between a first viewing angle and a second viewing angle.

[0024] Here, the first viewing angle (first viewpoint) is a viewing angle in a parallel plane of the map, and the second viewing angle (second viewpoint) is a viewing angle in a cut plane of the map. Specifically, this step determines an adjustment zoom ratio according to the adjustment index, for example, determines whether the two fingers of the user are pinched in or pinched out based on the position of the two fingers, and correspondingly zooms in and out the map display page according to the degree of pinching in or pinching out, and determines a rotation angle between the first viewing angle and the second viewing angle according to the adjustment index, for example, calculates the rotation angle at the two viewing angles based on the displacement of a reference point of the two fingers during the adjustment process.

[0025] The present disclosure provides a map display adjustment method and device, a storage medium, and a terminal. Compared with the related art, the embodiment of the present disclosure obtains adjustment gesture data when receiving an adjustment command for a map display page, the adjustment command is sent by a user operating a touch display on the map display page, the adjustment gesture data includes at least an adjustment start finger position and an adjustment end finger position, and analyzes the adjustment gesture data to obtain an adjustment indicator, the adjustment indicator is for identifying a position change of the adjustment gesture in the adjustment process of the current map display, and zooms in and out of the map display page and rotates it between a first viewing angle and a second viewing angle according to the adjustment indicator. The first viewing angle is a viewing angle within a parallel plane of the map, and the second viewing angle is a viewing angle within a cut plane of the map, so that an adjustment indicator capable of identifying a position change of an adjustment gesture is identified based on an adjustment finger position generated when a user adjusts a map display, and adjustments can be simultaneously performed on the map display page to rotate it at three viewing angles, i.e., zooming in / zooming out, rotating within the parallel plane of the map, and rotating within the cut plane of the map, according to the adjustment indicator. This allows a user to realize multi-viewpoint adjustment with a single operation, and eliminates the need for frequent switching operations to adjust map displays of different viewing angles, simplifying the adjustment operation of the map display page and improving the user experience.

[0026] As an improvement and extension of the specific embodiment of the above embodiment, in order to fully describe the specific implementation process of this embodiment, another map display adjustment method is provided, as shown in FIG. 2, the method includes the following steps:

[0027] In step 201, when a map display page adjustment command is received, adjustment gesture data is obtained.

[0028] Here, the adjustment command is sent by the user operating a touch display on the map display page, and the adjustment gesture data includes at least an adjustment start finger position and an adjustment end finger position. The concept interpretation and specific embodiment of this step can be referred to the corresponding description in step 101, and will not be repeated in the embodiments of this application.

[0029] In an embodiment of the present application, after step 201, the method may further include: determining whether the adjustment gesture is a two-finger gesture based on the adjustment gesture data; if the adjustment gesture is a one-finger gesture, calculating a drag displacement based on the adjustment start gesture position and the adjustment end gesture position, where the drag displacement is a corresponding displacement of a finger on the touch display during an adjustment process; and moving the map display page within a parallel plane of the map based on the drag displacement. If the adjustment gesture is a two-finger gesture, execute step 202.

[0030] In an embodiment of the present application, based on the acquired adjustment gesture data, it is determined whether the gesture is a one-finger gesture or a two-finger gesture. If it is determined to be a one-finger gesture, a map translation adjustment (map pan adjustment) is performed. If it is determined to be a two-finger gesture, the gesture data is further analyzed to obtain an adjustment indicator contained in the gesture data, thereby avoiding the problem of resource waste caused by directly analyzing the data and ensuring the accuracy of the adjustment of the map display page.

[0031] In step 202, a first center point and a second center point are calculated based on the adjusted start gesture position and the adjusted end gesture position respectively.

[0032] Here, the first center point is the midpoint of a line connecting the positions of the two fingers at the start of adjustment, and the second center point is the midpoint of a line connecting the positions of the two fingers at the end of adjustment.

[0033] In the embodiment of the present application, the center point between two fingers is used as a reference point, and the adjustment direction and adjustment amount in the adjustment process are determined according to the change in position of the reference point. However, of course, other points may be selected as reference points and used as the judgment criteria, and the embodiment of the present application is not particularly limited.

[0034] Specifically, the implementation manner of this step may be to obtain the position coordinates of two fingers during the user's operation process, and calculate the center point coordinate between the two fingers based on the position coordinates. The coordinate value of the finger position may be calculated according to a calculation method in the related art, and is not particularly limited in the embodiments of the present application.

[0035] For example, in the process of a user performing an adjustment of a map display page, the adjustment start gesture position is [(x1, y1), (x2, y2)], that is, the coordinates of the two fingers at the start of adjustment are x1, y1 and x2, y2 respectively, the adjustment end gesture position is [(x'1, y'1), (x'2, y'2)], and the calculated first center point position and second center point position are ((x1+x2) / 2, (y1+y2) / 2) and ((x'1+x'2) / 2, (y'1+y'2) / 2) respectively.

[0036] In step 203, a relative displacement between the first center point and the second center point on the touch display is calculated.

[0037] Since the coordinates of the two center points are calculated in the above step, in this step, the relative displacement can be calculated based on the coordinates of the two points.

[0038] In an embodiment of the present application, in the process of adjusting the map display page, the center point of the finger is used as a reference point, and the center point between the two fingers at the adjustment start position and the center point between the two fingers at the adjustment end position are calculated, respectively, whereby the corresponding displacement of the reference point in the process of adjusting the screen display can be identified, and further, rotation control is performed on the map display page according to the displacement.

[0039] In step 204, an adjustment ratio is calculated based on the adjustment start finger position and the adjustment end finger position.

[0040] Here, the adjustment ratio is the ratio of the distance between the two fingers at the end of the adjustment to the distance between the two fingers at the start of the adjustment.

[0041] Based on the content described in step 202 above, the acquired adjustment gesture data includes the positions of the two fingers at the start time and the end time of the adjustment process, so that the distance between the two fingers at the start time and the distance between the two fingers at the end time can be calculated, and the ratio of the two distances can be calculated to obtain the adjustment ratio during this step.

[0042] It should be noted that in the embodiment of the present application, the order of execution of step 204 and step 202 is not limited, that is, step 204 and step 202 may be executed in parallel, or each may be executed independently.

[0043] In step 205, the relative displacement and the adjustment ratio are identified as the adjustment index.

[0044] In the embodiment of the present application, the adjustment ratio and the relative displacement are calculated respectively, and the adjustment ratio and the relative displacement are identified as adjustment indexes. The zooming in and out of the map display page and the rotation of the map display page at different angles are controlled respectively according to these two adjustment indexes, thereby realizing multi-angle display adjustment of the map display page and ensuring the accuracy of the adjustment of the map display page.

[0045] In step 206, the map display page is scaled and rotated between a first viewing angle and a second viewing angle according to the adjustment indicator.

[0046] Here, the first viewing angle is a viewing angle in a parallel plane of the map, and the second viewing angle is a viewing angle in a cut plane of the map.

[0047] Specifically, this step may include the steps of respectively calculating a first displacement and a second displacement corresponding to the adjustment displacement, calculating a first angle and a second angle corresponding to the first displacement and the second displacement according to a preset algorithm, and rotating the map display page at the first visual angle according to the first angle and at the second visual angle according to the second angle, where the first displacement is a component of the adjustment displacement in the horizontal direction of the touch display, and the second displacement is a component of the adjustment displacement in the vertical direction of the touch display. The preset algorithm may be one or more of a matrix, a function, or a mapping relationship between a preset adjustment displacement and an adjustment angle, and a method of controlling the rotation of the map display page according to the rotation angle after determining the rotation angle may be an implementation in the related art, and is not particularly limited in the embodiments of the present application.

[0048] In one embodiment, this step may further include the steps of: enlarging the map display page according to the adjustment ratio if the adjustment ratio is greater than 1; and reducing the map display page according to the adjustment ratio if the adjustment ratio is less than 1.

[0049] When the adjustment ratio is greater than 1, the distance between the two fingers in the adjustment process becomes greater, that is, the user's finger state is a pinch out state, and it is determined that the viewpoint is enlarged, so the map display page is enlarged and displayed according to the adjustment ratio, and when the adjustment ratio is less than 1, the distance between the two fingers in the adjustment process becomes smaller, that is, the user's finger state is a pinch in state, and it is determined that the viewpoint is reduced, so the map display page is reduced and displayed according to the adjustment ratio. In actual application, the map enlargement / reduction ratio may be the same as the calculated adjustment ratio, or may be proportional to the adjustment ratio, that is, it may be enlarged at 1:1 according to the adjustment ratio, or may be enlarged / reduction according to a preset ratio relationship.

[0050] In an embodiment of the present application, the corresponding relative displacement of a reference point, for example, the center point of the line connecting the positions of the two fingers in the two-finger gesture in this embodiment, during the adjustment process is converted into an adjustment angle, and the adjustment angle is used to adjust the rotation of the map display page in two reference planes, respectively, and a zoom adjustment is performed on the map display page according to the change in the distance between the two fingers during the adjustment process. This allows the user to adjust the map display page at multiple angles by performing a single operation, and eliminates the need for the user to perform multiple operations to switch between map page displays with different perspectives. This simplifies the adjustment operation of the map page display and improves the user experience.

[0051] The present disclosure provides a method and apparatus for adjusting a map display. Compared with the related art, the embodiment of the present disclosure obtains adjustment gesture data when an adjustment command for a map display page is received, the adjustment command is sent by a user operating a touch display on the map display page, the adjustment gesture data includes at least an adjustment start finger position and an adjustment end finger position, analyzes the adjustment gesture data to obtain an adjustment indicator, the adjustment indicator is for identifying a position change of the adjustment gesture in a current map display adjustment process, and scales the map display page and rotates it between a first viewing angle and a second viewing angle according to the adjustment indicator, and One visual angle is a visual angle within a parallel plane of the map, and the second visual angle is a visual angle within a cut plane of the map.
