[0015] refer to figure 1 , which is a structural block diagram of the electronic map device 100 provided in the first embodiment. The electronic map device 100 includes a path acquisition unit 11 , a road segment splitting unit 12 , a road condition acquisition unit 13 , a rendering unit 14 , and a display unit 15 .
[0016] The path acquiring unit 11 is used to acquire the path between the starting point and the ending point. The starting point and the ending point can be set by the user. After the setting is completed, the path acquisition unit 11 calculates the optimal path between the two points according to the path finding algorithm. In other words, the path acquisition unit executes the method getPath(), and this method returns the path P. The path P can be expressed by, for example, a sequence of points Point, that is, P={Pointi=(xi,yi)|1<=i<=k}, Among them, xi and yi are the abscissa and ordinate of point Pointi respectively, and k is the total number of points. It...

[0029] refer to image 3 , the second embodiment of the present invention provides a method for presenting an electronic map route, which includes the following steps:
[0030] Step S201, obtaining the path between the start point and the end point;
[0031] Step S202, splitting the path into a plurality of sequentially connected sections;
[0032] Step S203, obtaining road condition information of each road section;
[0033] Step S204, according to the road condition information of each road segment, correspondingly adopt different formats to render the road segment; and
[0034] Step S205, displaying the rendered road section on the electronic map.
[0035] In step S201, the path P is returned, and the path P can be expressed by, for example, a sequence of points Point, that is, P={Pointi=(xi,yi)|1<=i<=k}, where xi and yi are respectively the horizontal positions of the point Pointi Scale and ordinate, k is the total number of points. Its specific implementation belongs...

Abstract
The invention relates to an electronic map device. The electronic map device comprises a path calculating unit, a path acquisition unit, a section splitting unit, a road condition acquisition unit, a rendering unit and a display unit. The path acquisition unit is used to acquire a path from a start to a stop. The section splitting unit is used to receive the path and split the path into a plurality of sequentially connected sections. The road condition acquisition unit is used to acquire road conditions related to the sequentially connected sections. The rendering unit is used to render each section in different formats according to the road condition of the section. The display unit is used to display the rendered section on an electronic map. The road conditions are presented by rendering the path in different formats, the presenting is more visual, and accordingly external buttons are avoided occupying display space of the map, and a user can conveniently drag the section with road condition information to adjust a path scheme according to the road condition. In addition, the invention provides an electronic map path presentation method.
Description
technical field [0001] The invention relates to an electronic map, in particular to an electronic map device and a method for presenting an electronic map path. Background technique [0002] Electronic maps, combined with positioning systems, have brought great convenience to people's travel and driving. At present, in addition to the basic route navigation service, the electronic map is gradually developing in the direction of intelligence. For example, the traffic information query service is provided in the electronic map at the same time. However, in the existing Internet map service, the display of bus transfer and self-driving route schemes is separated from the display of road condition information. [0003] For example, in an electronic map service, an independent external "Traffic Information" button is used. Users can click this button to display / hide the layer displaying traffic information. This external button occupies a part of the display of the map. space....
