Lane position determination method and device based on automatic driving vehicle and storage medium

Abstract

The embodiment of the invention discloses a lane position determination method and device based on an automatic driving vehicle and a storage medium. The lane position determination method comprises the steps: acquiring measurement data of a positioning lane; determining a lane positioning vector according to the measurement data; taking the lane positioning vector as an identification framework of a D-S evidence theory, and determining trust distribution parameters of the lane positioning vector; and determining a lane positioning position according to the trust distribution parameter of thelane positioning vector and the lane positioning vector. According to the technical scheme, an evidence theory method is adopted, and all sensor measurement data serve as an identification framework and are converted into evidences for fusion. The lane position determination method is different from conventional Kalman filtering and Bayesian estimation, does not need more historical data to obtainthe prior information of the sensor, is simple and convenient in calculation, is simple in system, and is suitable for the fusion of real-time data.

Description

technical field

[0001] The present disclosure relates to the technical field of automatic driving, and in particular to a method, device and storage medium for determining a lane position based on an automatic driving vehicle. Background technique

[0002] With the development of automobile intelligent technology, smart cars can realize automatic driving. In automatic driving technology, knowing the lane information of the road on which the vehicle is driving (such as the position of the lane line, the distance between the vehicle and the lane line, the position of the vehicle in the lane, etc.) will bring great assistance to the automatic driving vehicle, which can improve automatic driving. driving safety of the vehicle.

[0003] Due to the complex and changeable driving environment of self-driving vehicles, self-driving vehicles often install multiple sensors to perceive the surrounding environment, and location services are the main goals of multiple sensors. Current p...
