Embodiment Construction

[0049] figure 1 is a flowchart of a generating method according to an embodiment of the present invention. Such as figure 1 As shown, the present invention provides a method for generating a navigation route for automatic driving, which may generally include the following steps:

[0050] S10: Obtain relevant information about the planned route on the navigation map. The planned route can be automatically generated by the driver setting the starting point and destination from the navigation map, which can be commonly used products such as Gaode Map, Baidu Map, and Google Map.

[0051] S20: Map the relevant information of the planned route to the pre-acquired high-precision map, and obtain high-precision route information corresponding to the relevant information of the planned route on the high-precision map.

[0052] S30: Select key location points at least including intersection locations from the high-precision route information. For example, traffic light intersections,...

Abstract

The invention provides a navigation route generation method and device for automatic drive, and an automatic driving system, and belongs to the field of the automatic drive. The generation method comprises the following steps: acquiring related information of a planning path on a navigation map; mapping the related information of the planning path to a previously acquired high-precision map, and acquiring high-precision path information corresponding to the related information of the planning path on the high-precision map; screening out key location points at least including the intersectionlocation from the high-precision path information; inserting the preset amount of supplementary location points between the key location points, wherein the supplementary location point is extracted from the high-precision path information; computing according to the information of the key location point and the supplementary location point and generating a global navigation path for the automaticdrive. The navigation route generation method and system and the automatic driving system provided by the invention can improve the efficiency of generating a follow-up path for automatic driving, the flexibility and the instantaneity.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a navigation route generation method and device for automatic driving and an automatic driving system. Background technique [0002] In recent years, the development of web-side navigation map products has been relatively mature, and most of the maps on the market support secondary development and provide interfaces for secondary development, such as AutoNavi Maps, Baidu Maps, Google Maps and other products. The development of navigation map technology has created favorable conditions for optimizing the path generation method of automatic driving, but the navigation path generated by navigation map cannot meet the requirements of automatic driving path following in terms of accuracy. [0003] At present, the application of path following technology in the field of autonomous driving is generally to obtain road point information that can be used for following through high-precisio...
