AI Technical Summary

Technical Problem

The current high-precision map field trajectory collection relies on the accuracy of the equipment. Multiple collection runs cannot effectively control the accuracy, leading to the risk of accuracy anomalies and reducing the reliability of high-precision map data.

Method used

By acquiring the elevation difference between the current trajectory and other trajectories, abnormal trajectories are identified and filtered, and output to high-precision map production is stopped. Automatic quality control methods combined with manual quality control are used to improve data accuracy.

Benefits of technology

It can quickly identify and filter abnormal trajectories, reduce the risk of accuracy anomalies, improve the accuracy of field data and the reliability of high-precision maps, avoid waste of production capacity, and provide reliable data support for autonomous driving.

Abstract

This disclosure provides a quality control method, apparatus, electronic device, and medium for high-precision map trajectory acquisition, relating to the field of computer technology, and particularly to the fields of autonomous driving, high-precision maps, map navigation, and intelligent transportation. The method includes: acquiring the current trajectory and other trajectories on the same road from the trajectory acquired in the high-precision map; determining whether the current trajectory is abnormal based on the elevation difference between points on the current trajectory and corresponding points on the other trajectories; if the current trajectory is abnormal, filtering it out from the acquired trajectories and stopping the output of the current trajectory to the high-precision map production. This technical solution can quickly identify abnormal trajectories, reduce the risk of accuracy anomalies, improve the accuracy of field data, prevent abnormal trajectories from flowing into the high-precision map production process, and improve the reliability of the high-precision map.
