Abstract

Abstract: High definition(HD)maps have entered a phase of rapid development,where the accuracy of map data directly determines the safety and reliability of autonomous driving systems.The accuracy verification of HD maps is critical for ensuring the quality of map products.This paper systematically elaborates on accuracy verification methods for road-level HD electronic navigation maps.Taking HD maps generated by mobile surveying as an example,we propose a comprehensive framework covering validation processes,scenario selection,truth point collection and matching,and precision analysis.Validation experiments are conducted on expressways in Hefei,Liu'an and Chuzhou (Anhui province)demonstrate that this method effectively controls map data quality,achieving absolute accuracy of 50 cm (2σ)and relative accuracy of 20 cm (3σ),which meets the requirements for autonomous driving and intelligent transportation systems.The proposed methodology provides reusable technical references for the industry.

Key words: high definition(HD)map, accuracy verification, quality assessment, absolute accuracy, relative accuracy
