Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

The first embodiment of the invention provides an image processing method based on an electronic map, which can be applied to a terminal capable of displaying the electronic map.

Electronic maps, i.e., digital maps, are maps that are stored and referred to digitally using computer technology. The method for storing information in electronic map generally uses vector image storage, and the map scale can be enlarged, reduced or rotated without affecting the display effect.

Here, the above-mentioned terminal may be a mobile terminal or a fixed terminal, and the above-mentioned terminal includes, but is not limited to, a mobile phone, a notebook computer, a camera, a PDA, a PAD, a PMP, a navigation device, and the like. The mobile terminal may be connected to the internet, wherein the connection may be made through a mobile internet network provided by an operator, or through a network connection accessed to a wireless access point.

Here, if the mobile terminal has an operating system, the operating system may be UNIX, L inux, Windows, Android (Android), Windows Phone, or the like.

It should be noted that the type, shape, size, and the like of the display screen on the mobile terminal are not limited, and the display screen on the mobile terminal may be a liquid crystal display screen, for example.

In a first embodiment of the present invention, the display screen is used for providing a human-computer interaction interface for a user; in practical implementation, the processor of the terminal can control the map application to display the electronic map on the display screen.

Fig. 3 is a flowchart of an image processing method based on an electronic map according to an embodiment of the present invention, and as shown in fig. 3, the flowchart may include:

step 301: and after the planned route is determined on the electronic map, segmenting the planned route to obtain each segmented route.

In practical application, the processor of the terminal may determine a planned route according to the input starting point and the input end point, and control the planned route described above to be displayed on the electronic map for the user to view.

Here, the planned route may be regarded as a broken line formed by first sequentially connecting a plurality of line segments, fig. 4 is a schematic diagram of the planned route in the embodiment of the present invention, as shown in fig. 4, a starting point of the planned route is a, an end point of the planned route is B, and in fig. 4, the planned route is formed by 5 line segments, which are respectively denoted as a line segment C, a line segment D, a line segment E, a line segment F, and a line segment G.

It should be noted that, after the planned route is segmented, the length of each segmented route on the electronic map is the length corresponding to the scale of the current electronic map;

for an electronic map, a scale represents the ratio of the length of a line segment on the map to the actual length of a corresponding line segment on the ground, and the calculation formula can be: the ratio of distance on the graph to actual distance; the larger the scale is, the smaller the range represented by the map is, and the more detailed the content represented in the map is, the higher the precision is; the smaller the scale is, the larger the range represented on the map is, the simpler the reflected content is, and the lower the accuracy is; therefore, the electronic map can present more detailed contents by controlling the increase of the scale; on the contrary, the scale is reduced through control, so that the electronic map presents a larger range.

In order to achieve the purpose of presenting more details of the planned route, the scale can be increased to enable the scale of the electronic map to exceed a certain threshold, and thus, the electronic map can present more details of the planned route.

For example, after the planned route is determined on the electronic map, before the planned route is segmented, the control adjusts the scale of the electronic map so that the scale of the electronic map is larger than the set scale threshold.

The scale threshold value here may be preset, and in actual implementation, the scale threshold value preset by the user may be input to the terminal through a user input unit of the terminal.

In practical implementation, after the planned route is segmented, the obtained segmented route may include only one line segment, or may include at least two line segments;

for example, for the planned route shown in fig. 4, in example 1, after the planned route is segmented, 4 segmented routes are obtained, which are respectively denoted as segmented route 1, segmented route 2, segmented route 3, and segmented route 4; the sectional route 1 is composed of a line segment C and a line segment D, the sectional route 2 is a line segment E, the sectional route 3 is a line segment F, and the sectional route 4 is a line segment G.

For the planned route shown in fig. 4, in example 2, the obtained segmented route may include only a part of one line segment shown in fig. 4, for example, line segment 1 in fig. 4 is divided into a first part and a second part, and after the planned route is segmented, 3 segmented routes are obtained, which are respectively denoted as segmented route 5, segmented route 6 and segmented route 7, where segmented route 5 is the first part of line segment C, segmented route 6 is composed of the second part of line segment C and line segment D, and segmented route 7 is composed of line segment E, line segment F and line segment G.

Preferably, each segmented route obtained by segmenting the planned route is a line segment, so that corresponding detailed information near the segmented route is conveniently acquired in subsequent screenshot operation; as for the planned route shown in fig. 4, in example 3, after the planned route is segmented, 5 segmented routes are obtained, which are respectively denoted as segmented route a1, segmented route a2, segmented route A3, segmented route a4 and segmented route a5, segmented route a1 is line C, segmented route a2 is line D, segmented route A3 is line E, segmented route a4 is line F, and segmented route a5 is line G;

for the planned route shown in fig. 4, in example 4, after the planned route is segmented, 7 segment routes are obtained, which are respectively denoted as segment route B1, segment route B2, segment route B3, segment route B4, segment route B5, segment route B6 and segment route B7, where segment route B1 and segment route B2 jointly form segment C, segment route B3 is segment D, segment route B4 is segment E, segment route B5 and segment route B6 jointly form segment F, and segment route B7 is segment G.

Step 302: and performing screenshot on each obtained subsection route to obtain an image corresponding to each subsection route.

Here, the obtained respective segment routes may be written as 1 st segment route to nth segment route, n is a natural number greater than 1, and n represents the number of segment routes; in this way, after the 1 st to nth segment routes are obtained, screenshots are respectively carried out on the 1 st to nth segment routes, and images of the n segment routes are obtained.

Illustratively, after the ith segmentation route is subjected to screenshot, the obtained image corresponding to the ith segmentation route comprises the ith segmentation route, and i is 1 to n.

In an optional example, the area of the image corresponding to each obtained segmented route is smaller than a set area threshold, so that detail information which does not need to be obtained by a user can be avoided being intercepted, and actual requirements are met; in practical implementation, the processor of the terminal may determine the screenshot area of each segment route according to the set area threshold and the length of each segment route.

In actual implementation, the processor of the terminal may obtain the length and the position of each segment route, and control to generate a screenshot area for the corresponding segment route, so as to capture a screenshot based on the generated screenshot area to obtain an image corresponding to the corresponding segment route.

Step 303: sequentially splicing the images corresponding to the segmented routes according to the predetermined sequence of the segmented routes to obtain spliced images; wherein the predetermined sequence of the respective segment routes is consistent with the sequence of the planned route from the starting point to the end point, or the sequence of the planned route from the end point to the starting point.

That is, when the graphs are spliced, the graphs can be sequentially spliced according to the direction from the starting point to the end point of the planned route, and also can be sequentially spliced according to the direction from the end point to the starting point of the planned route, so that a complete image containing the whole planned route can be obtained.

When the screenshot is performed on each segment route, there may be an overlapping portion in the screenshot areas of two adjacent segment routes, that is, there may be an overlapping portion in the images corresponding to the two described adjacent segment routes.

In practical implementation, the processor of the terminal may determine the sequence of each segment route based on the sequence of the planned route from the starting point to the end point, or the sequence of the planned route from the end point to the starting point; and then, sequentially splicing the images corresponding to the segmented routes by a processor of the terminal according to the sequence of the segmented routes.

After the planned route is determined on the electronic map, the planned route is segmented to obtain each segmented route; screenshot is carried out on each obtained subsection route to obtain an image corresponding to each subsection route; sequentially splicing the images corresponding to the segmented routes according to the predetermined sequence of the segmented routes to obtain spliced images; wherein the predetermined sequence of the respective segmented routes is consistent with the sequence of the planned route from the starting point to the end point, or consistent with the sequence of the planned route from the end point to the starting point; therefore, the screenshot is only carried out aiming at the area nearby the planned route, and the actual application requirements are further met.

In addition, according to the first embodiment of the image processing method based on the electronic map, the area of the screenshot area is controlled to ensure that the screenshot is only performed on the area near the planned route, and meanwhile, the scale can be adjusted to enable the finally obtained image to include more detailed information, so that the detailed information near the planned route can be obtained, and the actual requirement can be met.

Second embodiment

In order to further embody the object of the present invention, further illustration is made on the basis of the first embodiment of the present invention.

In a second embodiment of the present invention, a flow of an image processing method based on an electronic map may include:

step 401: this step is the same as the step 301, and is not described herein again.

Step 402: and performing screenshot on each obtained subsection route to obtain an image corresponding to each subsection route.
