Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The following respectively describes specific embodiments of a method and an apparatus for generating a transient road surface on a map and related devices according to embodiments of the present invention.
The first aspect of the embodiments of the present invention relates to a method for generating a transition road surface on a map, and the method can perform acquisition and analysis on various end point data on roads with different accuracies, and further perform integration processing to form a smooth and mellow transition road surface, so that a navigation road map is displayed more beautifully, and a driver can conveniently and visually observe the navigation road map.

the road section Link1 in the ordinary road does not include a lane group unit, wherein the ordinary road data includes the geographical information of the ordinary road and the data information at the end points, etc.;
the high-accuracy road middle-road Link2 includes at least one lane group unit, and the high-accuracy road data includes not only all the contents of the above-mentioned general road data but also data of the lane group unit, such as lane edge line geographical information, end point information of a lane edge line, geographical information of the lane group unit, and the like.
Referring to fig. 2, a schematic diagram of a connection between a general road and a high-precision road before processing is shown, in which a map directly displayed in the diagram is very abrupt and very unattractive. In the method for generating a transition road surface provided by the embodiment of the present invention, the end point information of the connection between the road line segment Link1 in the ordinary road data and the lane group unit on the high-precision road needs to be determined from the data in fig. 2; wherein, there is an end point (refer to the position shown by the triangle in fig. 2) on the Link1 in the road segment in the ordinary road, and the end point is also located in the Link2 in the road segment in the high-precision road; there are two end points (refer to the positions shown by circles in fig. 2) on the lane group units connected in one high-precision road.
In an optional embodiment, before determining the endpoint at the connection, the method further includes: determining a scale value of the map, and comparing the scale value with a preset scale threshold value; and when the scale value is larger than the scale threshold value, judging that the scale is in a large scale state, and turning to the step of determining the end point of the connecting part.
In the process of map navigation or application, scales with different sizes are frequently switched due to different scenes. For example, the preset scale threshold is 1:200, when the scale is a large scale (e.g., 1:10, 1:25,1:50), the displayed data is the ordinary road data and the high-precision road data, and the transition situation of the road surfaces of roads with different precisions exists, and a series of processing needs to be performed on the transition road surface; when the scales are small scales (such as 1:500,1:1000), the data are displayed as the common road data, and the scenes of roads with different accuracies do not exist. The data are stored in two sets, and the two sets of data are respectively used for displaying the process of drawing the road map under different scales for displaying, if the scales are large scales, the obtained drawing data are the road segments in the high-precision road and the road segments in the common road for drawing and displaying, and simultaneously the transition road surface is drawn; if the scale is a small scale, the obtained drawing data is as follows: and directly drawing and displaying road segments in the ordinary road.

And S23, connecting the endpoints of the first group and the second group on the same edge.
Obtaining a first group of endpoints B and B 'and a second group of endpoints C and C' through the above steps S21 and S22; referring to fig. 4C, the endpoints on the same side are connected, that is, the endpoint B is connected to the endpoint C, and the endpoint B 'is connected to the endpoint C'. And a graph formed by the end points B, B ', C' and C is the transition road surface.
The step S21 and the step S22 are not executed in sequence, and the step S21 and the step S22 may be executed first, or may be executed simultaneously, which is not limited in this embodiment of the present invention.

Referring to fig. 5A, shape point data on the road line Link2 at a second predetermined distance from the first group of end points B and B ' is surfaced by a dotted-line surfacing algorithm to generate graphic data of a spreadable texture picture, and a third group of end points, namely end points D and D ', are obtained at the second predetermined distance from the graphic to the end point B or the end point B ', and are located between the first group of end points and the second group of end points. Of course, the second preset distance is smaller than the first preset distance. Referring to fig. 5B, the end point B is connected to the end point D, and the end point B 'is connected to the end point D'; connecting the terminal C with the terminal D, and connecting the terminal C 'with the terminal D'. And a graph formed by the end points C, D, B ', D ' and C ' is the transition road surface.
In an alternative embodiment, referring to fig. 6A, after the second group of end points is obtained, the second group of end points may be further extended by a third preset distance along the graph boundary after the surfacing processing is performed on the road line segment Link1 on the ordinary road, so as to obtain a fourth group of end points, which are respectively an end point E and an end point E'.

Because the processing flows of the common road data and the high-precision road data are different, and the displayed map has different hues, lines and the like, the gradient processing is required, and the specific process is to obtain the color data in the high-precision road data and the color data in the common road data, and achieve the rendering effect of gradually changing the color of the high-precision road to the color of the common road through the rendering processing.
