Abstract

The invention relates to the technical field of automatic driving, and discloses a method and device for determining a positioning error. The method comprises the steps that the device for determining the positioning error controls at least one marker to move to a first position, and first position information of the at least one marker is determined; second position information, determined by a field end server, of the at least one marker at the first position is obtained; and according to the first position information and the second position information, a positioning error of the field end server on the at least one marker is determined. The method is adopted to determine the positioning error of the at least one marker, the implementation is convenient, and a worker can correct the field end positioning system according to the positioning error of the at least one marker so as to ensure the positioning reliability of the field end positioning system.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a method and device for determining a positioning error. Background technique [0002] Autonomous driving is a mainstream application in the field of artificial intelligence (AI). Autonomous driving technology relies on the cooperation of computer vision, radar, monitoring devices and global positioning systems, so that motor vehicles can achieve Autopilot. Automated valet parking (AVP) means that a car that meets the requirements of automatic driving can automatically park the car in a parking space. The vehicle will drive to the parking space along the prescribed path to complete the parking process. [0003] With the continuous increase of urban car ownership, the problem of "difficult parking" in urban scenes has become increasingly prominent. In response to this problem, automakers and autonomous driving solution providers have launched various AVP...
