Abstract

The invention provides a relative position relation analysis method and system. The method comprises the following steps of acquiring a current position coordinate of a moving object on a field plane at the current moment, obtaining a curvilinear equation corresponding to the target lane line, wherein the plane corresponding to the target lane line belongs to the field plane, performing equal-interval discrete processing on the curvilinear equation to obtain a lane line discrete curve, wherein the lane line discrete curve comprises a plurality of discrete points, and traversing and analyzing to obtain a relative position relationship between the moving object and the target lane line according to each discrete point in the lane line discrete curve and the current position coordinate. According to the method, the calculation complexity and the calculation amount are reduced, and the relative position relation between the moving object and the target lane line is rapidly analyzed and determined.

Description

technical field

[0001] The invention relates to the technical field of data processing, in particular to a relative position relationship analysis and system. Background technique

[0002] In multiple algorithm modules such as planning and control in the fields of self-driving cars and robots, it is often necessary to obtain the relative positional relationship between the robot and the current planned trajectory, find the mapping point of the robot on the planned trajectory, and determine the relative position of the robot or vehicle. lateral to the lane markings.

[0003] In engineering, the method of brute force traversal is generally used to solve the problem, which takes a long time and is not friendly to processors with weak computing power. Therefore, how to avoid a large number of calculations and find the lateral position simply and efficiently is a technical problem urgently needed to be solved by those skilled in the art.
