Method and device for processing high-precision roads

Abstract

The invention discloses a processing method and device for high-precision roads, relates to the technical field of electronic maps, and mainly aims to eliminate "Z"-shaped routes between forks connecting high-precision road endpoints. The main technical solution of the present invention is: to obtain more than three high-precision roads connected to the same bifurcation intersection, the high-precision roads include two types of entering high-precision roads and exiting high-precision roads; selecting one type of high-precision roads Intercept another type of HD road to divide another type of HD road into an intercepted road segment and a reserved road segment, one end of the intercepted road segment is another type of HD road connected to the fork According to the connection relationship between another type of high-precision road and other high-precision roads in the branch intersection, the intercepted road section is fused, so that the intercepted road section is another type of high-precision road connected to the branch. The endpoint of the fork is no longer the endpoint connected to the fork.

Description

technical field [0001] The invention relates to the technical field of electronic maps, in particular to a method and device for processing high-precision roads. Background technique [0002] The fork is one of the components of electronic map data, and it is the basic data supporting navigation path planning and guidance services. [0003] In general, a branch intersection will connect more than three high-precision roads. Since the high-precision road expresses the actual shape of the road more accurately, the end points of the high-precision roads (the absolute positioning accuracy is generally at the meter level) connected at the branch intersection There will be a position difference between them, and this will cause the high-precision roads connected by the bifurcation intersections to fail to transition smoothly naturally. E.g, figure 1 The fork shown connects HD road A, HD road C, and HD road B. As shown in the figure, HD road A and HD road C are HD roads in the sa...

Problems solved by technology

[0003] In general, a branch intersection will connect more than three high-precision roads. Since the high-precision road expresses the actual shape of the road more accurately, the endpoints of the high-precision roads (the absolute positioning accuracy is generally at the meter level) connected at the branch intersection There will be a position difference between them, and this will cause the high-precision roads connected by the fork intersection to fail to transition smoothly naturally

E.g, figure 1 The fork shown connects HD road A, HD road C, and HD road B. As shown in the figure, HD road A and HD road C are HD roads in the same direction, and these two HD roads overlap Therefore, when planning the navigation path, a smoothly connected navigation path from high-precision road A to high-precision road C can be planned, and since the endpoint of high-precision road B is b, there is a position between b and a This will cause the planned navigation route from HD road A to HD road B to have a "Z"-shaped route, which obviously does not conform to the actual road direction
