AI Technical Summary

Technical Problem

In autonomous driving environments, the angle information for obstacle detection is easily affected by weather and environment, leading to inaccurate detection. Existing technologies that use the angle information from the previous frame to correct the current frame are prone to causing the angle information to lag, affecting vehicle driving safety.

Method used

By acquiring the target's historical trajectory information of obstacles, determining the radius of curvature and linear velocity information, and combining this with the minimum radius of curvature to calculate the obstacle's angular velocity information, the current detection angle is corrected to ensure the accuracy of the angle information.

Benefits of technology

This technology enables timely correction of angle information during obstacle detection, avoiding lag in angle information, improving the accuracy of autonomous driving detection, and ensuring safe vehicle operation.

Abstract

This invention discloses an obstacle detection angle correction method, electronic device, and storage medium. The method includes: acquiring historical trajectory information and current detection angle information of an obstacle; determining the radius of curvature of the obstacle based on the historical trajectory information; determining the linear velocity information of the obstacle; determining a first angular velocity information of the obstacle based on the linear velocity information and the radius of curvature; determining a second angular velocity information based on the minimum radius of curvature of the obstacle; and correcting the current detection angle information based on the second angular velocity information and the first angular velocity information to obtain the target angle information of the obstacle. This invention, through the above technical solution, ensures timely correction when the current detection angle information is incorrect, obtaining accurate detection angle information without causing lag in angle information, effectively improving the accuracy of autonomous driving detection and ensuring safe vehicle operation.
