Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] Such as figure 1 As shown, the implementation of the present invention comprises the following steps after starting:

[0051] 1) Obtain the number of entry / exit lanes at the intersection without lanes, record the number of entry lanes as N, and the number of exit lanes as M.

[0052] 2) According to the size relationship between N and M, calculate the number of connections that need to be established between each entry and exit lane, and the symbol of the connection number is marked as D.

[0053] 2.1) When N is less than M, it is a narrow entry and wide exit situation, and the number of connections that need to be established from entering the lane to exiting the lane is calculated. Specific algorithm:

[0054] D=((M-1) / N)+1

[0055] 2.2) When N is greater than M, it is the case of wide entry and narrow exit, and the number of connections t...

Abstract

The invention provides an algorithm of connection matching of entry and exit lanes of crossing without lane lines. The algorithm comprises the following steps of: acquiring the number of entry and exit lanes of the crossing without lane lines; judging whether the crossing is a wide entry and narrow exit crossing or a narrow entry and wide exit crossing or an entry and exit equaled crossing; calculating the number of exit / entry lanes needed to be connected with each entry / exit lane; and calculating a start number of the exit / entry lanes connected with one entry / exit lane. With the method, establishment of a connection relation between entry and exit lanes of the crossing without lane lines can be completed by a simple and high-efficiency algorithm.

Description

technical field [0001] The invention relates to the technical field of electronic map making, and in particular to an algorithm for calculating a reasonable exit lane when unmanned driving and advanced assisted driving cross an intersection area guided by no lane lines. Background technique [0002] With the application of high-precision navigation platforms and the gradual realization of unmanned driving, the road-level path planning of traditional navigation systems can no longer meet the requirements of high-precision navigation and unmanned driving. Path planning must be upgraded to the lane level, so a lane-level topological connection network must be established in the high-precision navigation map data. [0003] In the process of making high-precision maps, there are a large number of intersections without lane lines in the actual road conditions. Here, the lanes are disconnected. It is necessary to establish a connection relationship between the lanes entering the in...
