Embodiment Construction
[0064] The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.
[0065] Such as figure 1 As shown, an embodiment of the present invention provides a method for matching a high-precision lane group and a traditional road on the one hand, and its specific implementation includes the following steps:
[0066] 1. High-precision lane group connection line data reading: read in the vectorized data after digital processing of high-precision lane group connection lines.
[0067] After reading in the data, you need to ensure that the vectorized data is in order. That is, the front-back relationship between the coordinate points is consistent with the real world. Record the set of vectorized coordinate points of high-precision lane group connection lines as {P 1 ,P 2 ,P 3 ...P n},Such as Figure 6 shown;
[0068] T...

The invention relates to a method and device for matching a high-precision lane group with a traditional road. The method comprises the following steps: acquiring vectorial data of a plurality of lanegroup connecting lines in a high-precision map and vectorial data of a plurality of traditional roads in a traditional navigation map; carrying out intersection on the lane group connecting lines andthe traditional road successively, and establishing a set of the traditional roads which correspond to each lane group connecting line and are intersected with the lane group connecting line; filtering the set of the traditional roads, and acquiring the traditional roads which are matched with each lane group connecting line; and establishing a matching relation between the high-precision lane group and the traditional roads according to the matching relation between the lane group connecting line and the traditional roads. In a precision error range, complicated mathematical computation dimension is reduced to a planar level, and the matching relation between the high-precision lane group and the traditional roads is calculated by a simple section relation. An algorithm is implemented simply and easily, and is easy to understand.
Description
technical field [0001] The invention relates to the technical field of map navigation and data processing, in particular to a matching method and device for a high-precision lane group in a high-precision map and a traditional road in a traditional map. Background technique [0002] With the gradual application of next-generation high-precision navigation maps for active safety and driverless driving, map data has gradually moved from basic navigation and guidance functions to advanced functions of body control and active safety, and the lane-level path guidance function has been fully applied It is based on the advanced automatic driving of vehicles, so as to meet the basic needs of active safety and unmanned driving. [0003] In the process of high-precision map production, the points collected from the real road (such as laser point cloud data) will be vectorized, and finally the digital map data will be formed. The amount of lane-level data after vectorization is very l...
