Abstract

The invention discloses an intersection fitting guide map compilation method and device and a storage medium. The invention provides an intersection fitting graph compilation method. The intersection fitting graph compilation method comprises the steps of calling road network data; interference roads in the road network data are removed according to an intersection fitting strategy, and the intersection condition is simplified; and fitting and generating an intersection fitting graph according to the simplified intersection condition, wherein the intersection comprises an entrance edge and an exit edge of the intersection. According to the method, the efficiency and the coverage rate of generating the intersection fitting graph are high, the presented intersection fitting graph is basically consistent with the intersection, but the intersection form can remove interference roads according to a strategy, so that the intersection is simplified to a certain extent and is easier to understand, and a driver can quickly determine the road section where the driver walks so as to avoid walking on a wrong road.

Description

technical field [0001] The present invention relates to the field of road traffic, in particular to a preparation method, device and storage medium for a guide map for intersection fitting. Background technique [0002] With the rapid development of the road traffic system, the mileage and coverage of the road network are getting higher and higher, especially in cities, where the roads are becoming denser and more complex. In the process of using navigation software, drivers hope to get timely and accurate guidance, especially when facing complex intersections. At this time, if figure 1 As shown, a steering-based guidance method is created. In the prior art, only the guidance method of voice and steering cannot allow the driver to quickly understand the road section that should be taken, and it is easy to go the wrong way. Contents of the invention [0003] The technical problem mainly solved by the present invention is that the steering-based guidance method in road na...
