Vehicle positioning system evaluation method and device, equipment and storage medium

Abstract

The invention discloses a vehicle positioning system evaluation method and device, equipment and a storage medium, which relate to the field of automatic driving, and can be applied in the field of autonomous parking. According to the specific implementation scheme, the vehicle positioning system evaluation method is applied to electronic equipment; a vehicle positioning system and accurate navigation equipment are carried on a vehicle; a vehicle pose positioned by the vehicle positioning system is a target vehicle pose; and the vehicle pose positioned by the accurate navigation equipment is astandard vehicle pose. The method comprises the following steps: acquiring at least one vehicle pose point pair, wherein the vehicle pose point pair comprises the standard vehicle pose and a corresponding target vehicle pose; determining a standard main lane line corresponding to the vehicle pose point; calculating a positioning error which takes the standard main lane line as a reference according to the standard main lane line and the vehicle pose point pair; and evaluating the vehicle positioning system according to the positioning error.

Description

technical field [0001] The present application relates to the field of data processing technology, and in particular to automatic driving technology. Background technique [0002] With the maturity of artificial intelligence technology, autonomous driving technology has also developed rapidly. The vehicle positioning system is included in the automatic driving technology. The vehicle positioning system is a technology for locating the precise position and attitude of the self-driving vehicle in the world coordinate system. At present, it is necessary to evaluate the absolute accuracy of the vehicle positioning system to determine the accuracy of the vehicle pose determined by the vehicle positioning system. [0003] In the prior art, when evaluating the absolute accuracy of the positioning of the vehicle positioning system, the target lane line is compared with the standard main lane line, and the positioning error of the vehicle positioning system is determined according t...
