Problems solved by technology

[0004] In the process of proposing the present disclosure, the inventors found that in the prior art, Kalman filter technology is usually used to fuse the position information of the smart car obtained by various sensors to obtain an accurate position estimate of the smart car. Vehicle positioning does not involve the relationship between the lane and the vehicle, and the lane is not modeled and positioned, and conventional Kalman filtering or Bayesian estimation is used for sensor data fusion, which requires more historical data to obtain the prior experimental information, not suitable for real-time data fusion

Abstract

Embodiments of the present disclosure disclose a method, device, and storage medium for determining a lane position based on an automatic driving vehicle. The method includes: acquiring measurement data for positioning a lane; determining a lane positioning vector according to the measurement data; The positioning vector is used as the identification framework of the D-S evidence theory to determine the trust allocation parameter of the lane positioning vector; the lane positioning position is determined according to the trust allocation parameter of the lane positioning vector and the lane positioning vector. The technical solution adopts the method of evidence theory, which uses all sensor measurement data as a recognition frame, and converts it into evidence for fusion. This method is different from the conventional Kalman filter and Bayesian estimation. It does not need more historical data to obtain the prior information of the sensor, and the calculation is relatively simple, the system is simple, and it is suitable for real-time data fusion.

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 intelligent vehicle technology, intelligent vehicles can realize autonomous driving. In autonomous driving technology, knowing the lane information of the road the vehicle is traveling on (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.) Driving safety of the vehicle. [0003] Due to the complex and changeable driving environment of autonomous vehicles, autonomous vehicles often install a variety of sensors to perceive the surrounding environment, and positioning services are the main target of various sensors. The current positioning services mainly use RTK technology, IMU, lidar and vision for positioning, ...
