Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and particularly to a method and device for adjusting map display. Background Art

[0002] As the functions of mobile terminals become more and more abundant, daily life has become inseparable from intelligent terminal devices. Users can use mobile terminals for office work, shopping, housework, etc. Among the applications on mobile terminals, map applications are also one of the applications with relatively high demand. Map applications can provide accurate map data and plan travel routes according to user needs. Therefore, users can use map applications to search for destinations and perform route navigation, etc. When a three-dimensional map is displayed on a touch screen, users can also adjust the map display content through gestures, such as zooming in and out.

[0003] Currently, in the existing human-computer interaction implementation solutions for three-dimensional maps, usually a single finger is used to control the translation of the map display perspective, such as adjusting the horizontal / vertical movement of the map on the mobile terminal screen through a single finger, and two fingers are used to control the zooming in / out and rotation of the map display perspective, such as pinching two fingers to zoom out the map display perspective, or rotating two fingers based on the horizontal and vertical directions. However, in the existing three-dimensional map display control, when two fingers lock one interaction, other perspective transformations cannot be performed simultaneously. For example, only zooming and / or horizontal rotation, zooming and / or vertical rotation can be performed. If it is necessary to switch to other interaction methods, the two fingers need to be lifted off the screen and then re-operated, making the map display interaction operation cumbersome.

[0067] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully communicated to those skilled in the art.

[0068] In the existing three-dimensional map display control, when a two-finger interaction locks one interaction, other perspective transformations cannot be performed simultaneously. For example, only zooming and / or horizontal rotation, zooming and / or vertical rotation, etc. can be performed. If it is necessary to switch to other interaction methods, it is necessary to re-operate after the two fingers leave the screen, making the map display interaction operation cumbersome. An embodiment of the present invention provides a method for adjusting map display, such as Figure 1 shown, the method includes:

[0069] 101. When receiving an adjustment instruction for the map display page, obtain adjustment gesture data.

[0070] Among them, the adjustment instruction is sent by the user on the map display page through touching the display screen. The adjustment gesture data at least includes the starting finger position and the ending finger position of the adjustment. The touch display screen can be configured in a mobile terminal device, a venue guide device, a mobile robot, etc. The adjusted finger position can be determined by establishing a coordinate system in the plane where the touch display screen is located and according to the touch points of the fingers in this coordinate system. Specifically, it can be obtained by calling a preset interface or a preset algorithm when the finger touches the display screen. The embodiments of the present application do not make specific limitations on this.

[0071] In the embodiments of the present application, the adjustment instruction for the map display page can be sent when the user's finger briefly presses the touch display screen. 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 is to adjust the map display page, and then trigger sending an adjustment instruction for the map display page to the server, so that the server adjusts the map display page according to the user operation.

[0072] It should be noted that the terminal device can pre-download the corresponding map application program through the Internet and load the map data to store it locally or in the cloud, so that the map display page can be adjusted according to the user operation during use.

[0073] 102. Analyze the adjustment gesture data to obtain an adjustment index.

[0074] Among them, the adjustment index is used to identify the position change of the adjustment gesture during the current map display adjustment. Specifically, the adjustment index can be the distance between the fingers, or the position change of a certain reference point, such as the midpoint of the line connecting the positions of the two fingers, or the position change of the fingers on the touch display screen, etc. The embodiments of the present application do not make specific limitations on this.

[0075] In the embodiments of the present application, by analyzing the data generated when the user adjusts the map display page, data that can identify the position change of the adjustment gesture can be obtained. For example, according to the adjustment gesture data, it is determined that the adjustment gesture is that finger 1 moves from a 1 to a 2 , and finger 2 moves from b 1 to b 2 , then these two sets of finger data can be used as the adjustment index in this step.

[0076] 103. Zoom the map display page according to the adjustment index and rotate it between the first perspective and the second perspective.

[0077] Among them, the first perspective is the perspective within the map parallel plane, and the second perspective is the perspective within the map section plane. Specifically, this step can be to determine the adjustment scaling ratio according to the adjustment index. For example, it is judged whether the two fingers are pinched or stretched according to the positions of the two fingers of the user, and the map display page is scaled accordingly according to the degree of pinching or stretching. And the rotation angles of the first perspective and the second perspective are determined according to the adjustment index. For example, the rotation angles in the two perspectives are calculated according to the displacement of a reference point during the adjustment process of the two fingers.

[0078] The present invention provides a method and device for adjusting map display, a storage medium, and a terminal. Compared with the prior art, in the embodiment of the present invention, when receiving an adjustment instruction for the map display page, adjustment gesture data is obtained. The adjustment instruction is sent by the user on the map display page by touching the display screen. The adjustment gesture data at least includes an adjustment start finger position and an adjustment end finger position; the adjustment gesture data is parsed to obtain an adjustment index, and the adjustment index is used to identify the position change of the adjustment gesture during the current map display adjustment; the map display page is scaled and rotated in the first perspective and the second perspective according to the adjustment index. The first perspective is the perspective within the map parallel plane, and the second perspective is the perspective within the map section plane. It is realized to determine an adjustment index that can identify the position change of the adjustment gesture according to the adjustment finger positions generated when the user adjusts the map display, and perform adjustments in three perspectives of zooming in / out, rotation within the map parallel plane, and rotation within the map section plane on the map display page according to the adjustment index, so that the user can achieve multi-perspective adjustment through one operation, without frequently switching operations to adjust the map display in different perspectives, simplifying the operation of adjusting the map display page and improving the user experience.

[0079] Further, as a refinement and extension of the specific implementation manner of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another method for adjusting map display is provided, such as Figure 2 shown, this method includes:

[0080] 201. When receiving an adjustment instruction for the map display page, obtain adjustment gesture data.

[0081] Among them, the adjustment instruction is sent by the user on the map display page by touching the display screen. The adjustment gesture data at least includes an adjustment start finger position and an adjustment end finger position. The concept explanation and specific implementation manner in this step can refer to the corresponding description in step 101, and will not be repeated in the embodiments of this application.

[0082] In the embodiment of the present application, after step 201, it may further include: determining whether the adjustment gesture is a two-finger gesture according to the adjustment gesture data; if the adjustment gesture is a single-finger gesture, calculating a drag displacement according to the adjustment start finger position and the adjustment end finger position, where the drag displacement is the displacement corresponding to the finger on the touch display screen during the adjustment process; moving the map display page within the map plane according to the drag displacement. If the adjustment gesture is a two-finger gesture, then step 202 is executed.

[0083] In the embodiment of the present application, by judging whether the obtained adjustment gesture data is a single-finger gesture or a two-finger gesture, and performing map pan adjustment when it is judged to be a single-finger gesture, and further analyzing the gesture data to obtain the adjustment index included in the gesture data when it is judged to be a two-finger gesture, the problem of resource waste caused by directly performing data analysis is avoided and the accuracy of the map display page adjustment is ensured.

[0084] 202. Calculate a first center point and a second center point respectively according to the adjustment start finger position and the adjustment end finger position.

[0085] Wherein, the first center point is the midpoint position of the line connecting the positions of the two fingers at the start of the adjustment, and the second center point is the midpoint position of the line connecting the positions of the two fingers at the end of the adjustment.

[0086] In the embodiment of the present application, the center point between the two fingers is used as a reference point to facilitate judging the adjustment direction and adjustment amount during the adjustment according to the change of the reference point position. Of course, other point positions can also be selected as reference points for judgment and measurement, and the embodiment of the present application does not make specific limitations on this.

[0087] Specifically, the implementation manner of this step can be to obtain the position coordinates of the two fingers of the user during the operation process, and calculate the center point coordinates between the two fingers according to the position coordinates. The coordinate values of the finger positions can be calculated in the existing technology, and the embodiment of the present application does not make specific limitations on this.

[0088] Exemplarily, during the process of the user performing the map display page adjustment, the adjustment start finger position is [(x 1 ,y 1 ),(x 2 ,y 2 )], that is, the coordinates of the two fingers at the start of the adjustment are x 1 ,y 1 and x 2 ,y 2 , and the adjustment end finger position is [(x 1 ′ ,y 1 ′ ),(x2 ′ , y 2 ′ ), then the first center point position and the second center point position can be calculated respectively as follows:

[0089] and

[0090] 203. Calculate the relative displacement between the first center point and the second center point on the touch display screen.

[0091] Since the coordinates of the two center points have been calculated in the above steps, the relative displacement can be calculated according to the coordinates of the two points in this step.

[0092] In the embodiment of the present application, during the process of adjusting the map display page, the center point of the finger is used as a reference point, so as to calculate the center point between the two fingers at the starting position of the adjustment and the center point between the two fingers at the ending position of the adjustment respectively, and then the displacement corresponding to the reference point during the adjustment of the screen display can be determined, and further, the display page can be rotated and controlled according to the displacement.

[0093] 204. Calculate the adjustment ratio according to the starting finger position of the adjustment and the ending finger position of the adjustment.

[0094] Wherein, 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.

[0095] According to the content described in step 202 above, the obtained adjustment gesture data includes the positions of the two fingers at the starting moment and the positions of the two fingers at the ending moment during the adjustment process. Therefore, the distance between the two fingers at the starting moment and the distance between the two fingers at the ending moment can be calculated, and then the ratio of the two distances can be obtained to get the adjustment ratio described in this step.

[0096] It should be noted that in the embodiment of the present application, the execution order of step 204 and step 202 is not limited, that is, step 204 and step 202 can be executed in parallel or singly.

[0097] 205. Determine the relative displacement and the adjustment ratio as the adjustment index.

[0098] In the embodiment of the present application, by calculating the adjustment ratio and the relative displacement respectively, and determining the adjustment ratio and the relative displacement as the adjustment index, it is convenient to control the zooming of the map display page and the rotation of the map display page at different angles according to these two adjustment indexes, which can not only realize the display adjustment of the map display page at multiple angles, but also ensure the accuracy of the adjustment of the map display page.

[0099] 206. Zoom the map display page according to the adjustment index and rotate it between the first view angle and the second view angle.

[0100] Among them, the first view angle is the view angle within the plane parallel to the map, and the second view angle is the view angle within the section plane of the map.

[0101] Specifically, this step may include: respectively calculating a first displacement and a second displacement corresponding to the relative displacement; calculating a first angle and a second angle corresponding to the first displacement and the second displacement respectively according to a preset algorithm; rotating the map display page at the first angle in the first view angle and at the second angle in the second view angle. Among them, the first displacement is the component of the relative displacement in the horizontal direction of the touch display screen, and the second displacement is the component of the relative displacement in the vertical direction of the touch display screen. The preset algorithm may be one or more of a matrix, a function, or a pre-set mapping relationship between the relative displacement and the adjustment angle. The method of controlling the map display page to rotate according to the rotation angle after determining the rotation angle may be an implementation method in the prior art, and the embodiments of the present application do not make specific limitations on this.

[0102] Further, this step may also include: when the adjustment ratio is greater than 1, zoom in the map display page according to the adjustment ratio; when the adjustment ratio is less than 1, zoom out the map display page according to the adjustment ratio.

[0103] When the adjustment ratio is greater than 1, it indicates that the distance between the two fingers increases during the adjustment process, that is, the state of the user's fingers is in a stretched state. At this time, it is determined as a zoom-in view angle, so the map display page is enlarged and displayed according to the adjustment ratio; when the adjustment ratio is less than 1, it indicates that the distance between the two fingers decreases during the adjustment process, that is, the state of the user's fingers is in a pinched state. At this time, it is determined as a zoom-out view angle, so the map display page is reduced and displayed according to the adjustment ratio. In actual application, the map zoom ratio may be the same as the calculated adjustment ratio, or may be positively correlated with the adjustment ratio, that is, it may be enlarged according to the adjustment ratio of 1:1, or may be scaled according to a pre-set ratio relationship.

[0104] In the embodiment of the present application, by converting the relative displacement corresponding to a reference point, such as the center point of the line connecting the positions of two fingers in a two-finger gesture in this embodiment, during the adjustment process into an adjustment angle, and using this adjustment angle to respectively adjust the rotation of the map display page in two reference planes, and performing a zoom adjustment on the map display page according to the change in the distance between the two fingers during the adjustment process, it is realized that the user can adjust the map display page at multiple angles with one operation, so that the user does not need to perform multiple operations to switch the map page display of different perspectives, thereby simplifying the adjustment operation of the map page display and improving the user experience.

[0105] The present invention provides a method and device for adjusting map display.
