Example Embodiment
[0021] Such as figure 1 As shown, a high-precision map route planning system includes the following modules:
[0022] The matching module 10 is used to obtain the starting point and the ending point of the planned route; and matching the starting point and the ending point to a traditional map and a high-precision map.
[0023] Traditional maps refer to existing road-level navigation maps. Traditional maps are data in binary format (such as Kiwi format). The data used for route planning refers to Region data in Kiwi format. The result of traditional route planning is obtained by combining the A* algorithm with Region data in the Kiwi format. Since it is not the focus of the embodiment of the present invention, the traditional route planning method will not be introduced in detail. High-precision maps refer to lane-level navigation maps.
[0024] The traditional map route planning module 20 is used to plan the shortest route road list between the start point and the end point on the ...
