It should be noted that the navigation image display method provided by the embodiment of the present application is generally performed by the

terminal devices

101, 102, and 103. Accordingly, the navigation image display device is generally disposed in the

terminal devices

101, 102, and 103.

It should be understood that the number of terminal devices, networks, and servers in Figure 1 is merely illustrative. Depending on the implementation needs, there can be any number of terminal devices, networks, and servers.

With further reference to FIG. 2a, a flowchart 200 of one embodiment of a navigation image display method is illustrated that includes the following steps:

Step 201: Obtain a starting point coordinate and an ending point coordinate.

In this embodiment, the electronic device (for example, the

terminal device

101, 102, 103 of FIG. 1) on which the navigation image display method runs transmits the acquired departure point coordinates and the end point coordinates to the navigation device (for example, the server 105 of FIG. 1). ). The electronic device may be a device with a navigation module (such as a GPS module) such as a smart phone or a smart tablet; the navigation device may be a device capable of providing positioning information, such as a map server and a navigation server.

Step 202: Generate a navigation path according to the starting point coordinates and the ending point coordinates.

After receiving the coordinates of the departure point and the coordinates of the end point, the navigation device performs positioning on the map according to the coordinates of the departure point and the coordinates of the end point, and transmits the positioning data to the terminal; the terminal generates a navigation path from the coordinates of the departure point to the coordinates of the end point according to the positioning data. Usually, there are multiple navigation paths, and the navigation path can be regenerated according to the real-time location of the terminal.

Step 203: Determine a navigation initial image according to the navigation path.

It can be seen from the description of step 202 that there are multiple navigation paths. Generally, the navigation paths are planned according to actual routes. Therefore, the navigation paths are mostly irregular curves. In order to display all the navigation paths on the screen of the terminal, all navigation is required. The path is displayed reasonably.

With further reference to FIG. 2b, in some optional implementation manners of this embodiment, step 203 may include the following steps:

Step 2031: Acquire a longitude coordinate area and a latitude coordinate area corresponding to the navigation path.

The navigation path is mostly a curve and is composed of a plurality of points. Therefore, the longitude coordinate and the latitude coordinate of each point can be acquired, and then the longitude coordinate area and the latitude coordinate area of the navigation path are obtained by the longitude coordinate and the latitude coordinate of all the points.

Step 2032, determining a path rectangle according to the longitude coordinate area and the latitude coordinate area.

The screen of the terminal is usually a rectangle. To this end, a rectangle may be determined by the boundary value of the longitude coordinate area of each navigation path and the boundary value of the latitude coordinate area, and used to represent the display area occupied by the navigation path; The corresponding rectangles are superimposed to obtain a path rectangle containing all rectangles. The path rectangle is determined according to the boundary value of the longitude coordinate region of all navigation paths and the boundary value of the latitude coordinate region, that is, the path rectangle contains exactly all the rectangles.

In step 2033, the geometric center of the path rectangle is taken as a midpoint, and the path rectangle is enlarged according to a set ratio to obtain a road network rectangle, and the map image covered by the road network rectangle is used as a navigation initial image.

At this time, the path rectangle obtained in step 2032 can only partially display the image around the coordinates of the departure point and the coordinates of the end point. To this end, the path rectangle can be appropriately enlarged, so that the enlarged rectangular image includes the image around the coordinates of the departure point and the coordinates of the end point. A method of amplifying the geometric center of the path rectangle as a midpoint can be employed. The enlarged path rectangle is used as a road network rectangle, and the map image covered by the road network rectangle is used as the navigation initial image. For example, the path rectangle is enlarged by 10% (or other values) to obtain a road network rectangle or the like.

Step 204: Convert the navigation initial image into a navigation image according to display area information of the terminal screen.

The navigation initial image is obtained according to the navigation path. In order to enable the navigation initial image to be properly displayed according to the screen of the terminal, the navigation initial image needs to be adjusted.

In some optional implementation manners of this embodiment, step 204 may further include: displaying The display area information may further include display size information and/or display resolution information; The display resolution information can affect the display effect of the navigation image to a certain extent. At this time, the converting the navigation initial image into a navigation image according to the display area information of the terminal screen includes: scaling the navigation initial image according to the display size information and/or display resolution information, and obtaining navigation image.

Step 205: Display the navigation image according to status information of the terminal screen.

The status information of the terminal screen usually includes a lighting state and a lock screen state. The navigation image is displayed differently for different states.

In some optional implementation manners of the embodiment, if the display state information of the terminal screen is the screen lighting state, the navigation image is displayed. At this time, the navigation image is the same as the common navigation image, and the real-time dynamic display is performed. .

If the display state information of the terminal screen is the screen lock screen state, the navigation image is displayed on the screen lock screen interface. In this way, the purpose of displaying the navigation image can also be obtained on the lock screen interface of the screen lock screen. Since the terminal screen is in the lock screen state, this greatly reduces the power consumption of the terminal. At this point, the navigation image can be properly processed to meet the needs of the lock screen interface.

In some optional implementation manners of this embodiment, with further reference to FIG. 2c, displaying the navigation image on the screen lock screen interface includes the following steps:

Step 2051: Acquire the navigation image.

The user queries the navigation image when the terminal screen is in the locked state, usually because the user needs to query the navigation information of the current time. Therefore, the real-time navigation image is acquired at this time. Since the network data is not displayed during the screen lock screen, the display of the navigation image on the screen lock screen greatly saves the network traffic and saves the processing of the terminal. ability.

Step 2052: Perform navigation path drawing on the navigation image by using a set drawing option, the drawing option being at least one of the following: including a color option and a line option.

Under the lock screen interface, the display function of the screen is usually not fully tuned, and the performance of the effect display or information processing is not high. Therefore, the navigation path can be highlighted, such as rendering the navigation path with a striking color on the navigation image, or thickening the navigation path with a thick line, and can also be highlighted by other means, here No longer.

Step 2053, displaying the drawn navigation image.

When the drawn navigation image is displayed, the drawn navigation image can be directly used, and the drawn navigation image can be screenshotd, and the screenshot is displayed on the lock screen interface.

In some optional implementation manners of the embodiment, the status information of the terminal screen may further include the placement status information of the terminal screen, such as the terminal screen being placed horizontally or vertically, and the horizontally placed or vertically placed may be passed through a device such as a gyroscope. Test. Accordingly, the navigation image should also be adjusted based on the placement status information. Therefore, the displaying the navigation image according to the state information of the terminal screen further includes displaying the navigation image according to the placement state information of the terminal screen.

In this embodiment, the navigation path is first generated according to the coordinates of the starting point and the coordinates of the end point, and then the navigation initial image is obtained. On the basis of obtaining the initial image of the navigation, the navigation image is obtained by combining the real area information of the terminal screen, and finally according to the state information of the terminal screen. The navigation image is displayed such that the navigation image can display the navigation image according to various states of the terminal screen, thereby saving power of the terminal.
