Description

Method and device for processing navigation path information

[ technical field ] A method for producing a semiconductor device

The present invention relates to the field of navigation technologies, and in particular, to a method and an apparatus for processing navigation path information.

[ background ] A method for producing a semiconductor device

With the rapid development of computer technology, many applications in electronic equipment are emerging, which greatly facilitates the life of people.

For example, a navigation application is a very frequently used application in the electronic devices of the prior art. When the user goes out, the driving path can be obtained through navigation, and great convenience is brought to the life of the user. In the conventional navigation, when a user requests a navigation path from a starting point to an ending point, a navigation application may calculate at least two navigation paths for the user, the user selects one navigation path as a driving path, and then the navigation application displays a route of the navigation path for the user, and in general, the route of the navigation path displayed by the navigation application is displayed on a map as a base map. In order to facilitate the user to clearly recognize the route of the navigation path from the base map, in the prior art, the route of the navigation path is usually displayed in a bold type. Or coloring the route of the navigation route with a color different from that of the base map area.

However, in the prior art, the route of the navigation route is still very similar to the map as the base map, so that the identification degree is very low when the route of the navigation route is displayed on the map, and the user can hardly identify the route of the navigation route from the map.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a flowchart of a method for processing navigation path information according to an embodiment of the present invention. As shown in fig. 1, the method for processing navigation path information in this embodiment may specifically include the following steps:

100. acquiring path information of a user requesting navigation;

101. performing hand-drawing processing on the navigation path information;

102. and displaying the path information of the navigation after the hand-drawing processing to the user.

The executing body of the processing method of the navigation path information of the embodiment may be a processing device of the navigation path information, and the processing device of the navigation path information may be specifically applied to a navigation application, so as to process the navigation path information acquired by the navigation application. The navigation application of the present embodiment may also be embedded in a map application or other applications. Or the navigation application of the embodiment can also be directly installed in the mobile terminal or other electronic devices.

In this embodiment, the user may request navigation from the start point to the end point to the navigation application, and the navigation application plans the path information of the navigation according to the request of the user. The processing means of the navigated route information may obtain the navigated route information from the navigation application. In order to facilitate the user to distinguish the navigation path information from the map as the base map, in this embodiment, the navigation path information is subjected to hand-drawing processing, and finally the navigation path information after the hand-drawing processing is displayed to the user. Because the style of the navigation path information after hand-drawing processing is completely different from the style of the navigation path information of the map, the identification degree of the navigation path information can be greatly increased. The hand-drawing processing procedure of this embodiment is mainly used to change the style of the navigation path information, and set the navigation path information in the common map style into the format of hand-drawing processing, so that after the navigation path information after hand-drawing processing is displayed to the user, the common map is displayed as a base map at the bottom of the navigation path information, and the user can clearly recognize the navigation path information after hand-drawing processing from the base map.

The method for processing the navigation path information of the embodiment comprises the steps of acquiring the path information which is requested to be navigated by a user; performing hand-drawing processing on the navigation path information; and displaying the path information of the navigation after the freehand drawing processing to the user. By adopting the technical scheme of the embodiment, the style of the navigation path information can be changed, so that the style of the navigation path information is different from the style of the map serving as the base map, the identification degree of the navigation path information during display can be greatly improved, and a user can conveniently identify the navigation path information from the map.

Further optionally, the navigation path information in the above embodiment includes not only the road, but also various Points Of Interest (POI) around the road. For example, POIs within a range of 500 meters or 100 meters around a road in a navigation path may be specifically included. Correspondingly, in this case, the step 101 "perform hand-drawing processing on the navigation path information" in the above embodiment may specifically include the following steps:

(a1) Performing hand-drawing processing on the road in the navigation path information;

(a2) Performing hand-drawing processing on each POI around the road in the navigation path information;

further optionally, the step (a 1) "performing hand-drawing processing on the road in the navigated path information" may specifically include the following steps:

(b1) Extracting a coordinate point of a corner of a road in the navigation path information;

(b2) The coordinate point of the curve of the road is moved, so that the curve degree of the curve is smaller.

The hand-drawing processing mode of the embodiment enables the edges and corners of the road in the navigation path information to be not so clear, and the artistic display is more likely to be realized. For example, a coordinate point of a corner of a road in the navigated path information may be extracted and then moved so that the curve is less, the curve is more gradual, and there are no edges.

Further optionally, on the basis of the technical solution of the above embodiment, before the step (a 2) "performing hand-drawing processing on each POI around the road in the navigated route information", the method may further include: and according to the types of the POI set by the user, screening out each POI corresponding to the type from a plurality of original POIs around the road in the navigation path information.

For example, in real life, there are various types of POIs, such as restaurants, service stations, shopping malls, museums, and so forth. The user may only be interested in certain types of POIs in a route planning, for example, the user may only be interested in service stops on the road when requesting to navigate a high-speed route, but not in surrounding shopping malls or museums. In this case, when the user requests navigation, the type of the POI to be paid attention to may be set at the same time, so that the navigation route information processing apparatus may screen out each POI corresponding to the user-set type from a plurality of original POIs around the road in the navigation route information according to the type of the POI set by the user. When a user requests navigation, one POI type may be set, or a plurality of POI types may be set. Before performing hand-drawing processing on each POI around the road in the navigation path information, the POI corresponding to the POI type set by the user can be screened from all POIs in the navigation path information.

Further optionally, on the basis of the technical solution of the above embodiment, the step (a 2) "performing hand-drawing processing on each POI around the road in the navigated route information" may specifically include the following steps:

(c1) Acquiring a hand drawing of each POI;

(c2) And setting the hand-drawn graph of the corresponding POI in the navigation path information according to the position of each POI relative to the road.

The hand drawing of the POI according to the present embodiment may be a generalized hand drawing set in advance according to the type of the POI, for example, POI of types such as museums, schools, parks, and service stations, each type having a common feature, and the generalized hand drawing may be adopted. The corresponding relationship between various types of generalized hand drawings and the types of corresponding POI can be established in advance and stored in a generalized hand drawing library to be acquired during use. In practical applications, there are some POIs without the same type, which have their own exclusive features, such as great wall, tiananmen, etc., and such POIs can be provided with their own exclusive hand drawings. Similarly, the corresponding dedicated hand-drawing graph can be established in advance according to the types of the various dedicated POIs, and the corresponding relationship between the dedicated POIs and the corresponding dedicated hand-drawing graph is established and stored in a dedicated hand-drawing graph library. In practical application, no matter the exclusive hand drawing or the generalized hand drawing, in order to be clearly displayed, the maximum size and the minimum size which can be displayed need to be set, and when the hand drawing is set in the navigation path information, the hand drawing can be zoomed, so that the hand drawing can be conveniently cleaned and displayed. For example, during the specific zooming, according to the size of the display interface, the viewing of the whole interface cannot be greatly influenced, and roads in the navigation path information around the hand-drawing graph cannot be shielded, and in the zooming process, the hand-drawing graph needs to be ensured to be between the maximum size and the minimum size, so as to ensure the clear display of the hand-drawing graph.

For example, when the POI types set by the user include at least two types, and the priorities of the at least two types are not the same; at this time, the corresponding step (c 2) "sets the hand-drawn graph of the corresponding POI in the navigation route information according to the position of each POI relative to the road", which may specifically include the following steps:

(d1) Zooming the corresponding hand-drawn graph of the POI according to the priority level of the type of each POI, so that the size of the hand-drawn graph of the POI with high priority level is larger than that of the hand-drawn graph of the POI with low priority level;

(d2) And translating the hand-drawn graph of the corresponding POI into the navigation path information according to the position of each POI relative to the road.

The priority of the POI types in this embodiment is also set by the user, for example, when the user uses navigation, the user may select a first-level POI type through an option of the interface, where the first-level POI type may be a POI type with a high priority, and then may further select a second-level POI type, which may be a POI type with a lower priority than the first-level POI type. Because the interface size is limited when the navigation path information is displayed, in order to ensure that all the hand-drawn images of the POIs can be normally displayed, the size of the hand-drawn image of the POI corresponding to the POI type with high priority, which is focused by the user, can be adjusted to be larger than the size of the POI type with low priority. And then translating the hand-drawn graph of the corresponding POI into the navigation path information according to the position of each POI relative to the road, wherein the hand-drawn graph is translated into the navigation path information and cannot shield the road in the navigation path information, otherwise, the size of the hand-drawn graph is continuously reduced. Further optionally, on the basis of the technical solution of the foregoing embodiment, after the step (c 1) "acquires the hand-drawn graph of each POI", before the step (c 2) "sets the hand-drawn graph of the corresponding POI in the navigation route information according to the position of each POI relative to the road", the method may further include the following steps:

(e1) Judging whether the distance between any two adjacent POIs is multiplied by a scale of the navigation path information and is larger than a preset distance threshold value or not; if yes, directly executing the step (c 2); otherwise, when the distance between two adjacent POIs is multiplied by the scale of the navigation route information and is less than or equal to a preset distance threshold value, executing the step (e 2);

(e2) Zooming the hand-drawn graph of the POI close to the starting point of the navigation; performing step (e 3);

(e3) Translating the zoomed hand-drawn graph of the POI close to the starting point into the navigation path information according to the position of the POI close to the starting point in the two adjacent POIs relative to the road; performing step (e 4);

(e4) When a user goes from a starting point to a terminal point, removing a hand-drawn graph of a POI close to the starting point from navigation path information after passing through the POI close to the starting point in two adjacent POIs; performing step (e 5);

(e5) Carrying out zooming processing on the hand-drawn picture of the POI far away from the starting point; performing step (e 6);

(e6) And translating the hand-drawn graph of the POI which is far away from the starting point in the two adjacent POIs after the zooming processing into the navigation path information according to the position of the POI which is far away from the starting point in the two adjacent POIs relative to the road.

In the processing of the navigation route information according to the present embodiment, the hand-drawn images of the POIs are displayed in the same size. At this time, after the hand-drawn graph of each POI is acquired, it may be determined whether a distance between any two adjacent POIs multiplied by a scale of the navigation path information is greater than a preset distance threshold, where the preset distance threshold of this embodiment is equal to a length of a long side of a minimum display size of the hand-drawn graph. The distance between any two adjacent POIs is multiplied by the scale of the navigation path information, and is equal to the display distance between the two POIs when the two POIs are displayed on the current interface, if the display distance between the two POIs is larger than the length of the long side of the minimum display size of the hand drawing, the current two POIs can be normally displayed on the current interface, and at the moment, the hand drawing of the corresponding POI can be set in the navigation path information directly according to the position of each POI relative to the road.

And when the display distance between the two POIs is smaller than or equal to the length of the long side of the minimum display size of the hand drawing, the two POIs are crowded together when being displayed simultaneously, and the normal display cannot be realized. In this case, the two POIs may be displayed in a time-sharing manner, when the user travels to a position before the POI close to the start point of the navigation in the two adjacent POIs, the hand-drawn image of the POI close to the start point of the navigation is zoomed, and the hand-drawn image of the POI close to the start point after the zoom processing is translated into the navigation path information according to the position of the POI close to the start point in the two adjacent POIs relative to the road. After the user passes through the POI which is close to the starting point in the two adjacent POIs, removing the hand-drawn graph of the POI which is close to the starting point from the navigation path information and carrying out zooming processing on the hand-drawn graph of the POI which is far from the starting point; and translating the zoomed hand-drawn picture of the POI far away from the starting point in the two adjacent POIs into the navigation path information according to the position of the POI far away from the starting point in the two adjacent POIs relative to the road. Therefore, in the driving process of the user, the hand-drawn pictures of the two POIs can be displayed to the user through time-sharing display.

Further optionally, on the basis of the technical solution of the above embodiment, the step (c 1) "acquiring the hand-drawn graph of each POI" may specifically include the following steps:

(f1) Judging whether the exclusive hand-drawing library has exclusive hand-drawing of each POI or not; if yes, executing step (f 2), otherwise, executing step (f 3);

(f2) Acquiring an exclusive hand drawing of the corresponding POI as the hand drawing of the POI; and (6) ending.

(f3) Acquiring the type of the POI from a POI information base; performing step (f 4);

(f4) Acquiring a generalized diagram corresponding to the type of the POI from a generalized freehand diagram library according to the type of the POI; performing step (f 5);

(f5) The generalized graph is used as a hand-drawn graph of the POI.

Since the number of the POIs drawn by the dedicated hand is less than that of the POIs drawn by the generalized hand, in the embodiment, when the hand-drawn graph of each POI is obtained, whether the dedicated hand-drawn graph of each POI exists in the dedicated hand-drawn graph library or not can be judged; if the POI exists, the special hand-drawing graph of the POI can be directly obtained to be used as the hand-drawing graph of the POI. Otherwise, if the POI does not exist, the type of the POI can be obtained from the POI information base at the moment; then acquiring a generalized diagram corresponding to the type of the POI from the generalized freehand diagram library according to the type of the POI; and the generalized graph is used as a hand-drawn graph of the POI. The navigation application is provided with a POI information base, and the POI information base can comprise names, identifications, positions, types, display icons and the like of POIs.

By adopting the technical scheme, the method for processing the navigation path information can change the style of the navigation path information, so that the style of the navigation path information is different from the style of a map serving as a base map, thereby greatly improving the identification degree of the navigation path information during display and facilitating a user to identify the navigation path information from the map.
