Problems solved by technology
[0004] First, the existing positioning technology is greatly affected by environmental factors, resulting in a large error between the location obtained by positioning and the actual location
[0005] Second, the accuracy of the geographical location obtained by positioning is not high, which makes it difficult to match the geographical location obtained by positioning with the location in the actual road scene, which in turn leads to a high rate of misjudgment and misoperation by drivers

Embodiments of the present disclosure disclose a vehicle lane-level positioning method, device, electronic equipment, and computer-readable medium. A specific implementation of the method includes: acquiring the vehicle lane line information sequence set, vehicle pose matrix set, and map information sequence set; performing validity checks on the lane line information sequence set, vehicle pose matrix set, and map information sequence set , to obtain the validity test result; in response to the validity test result meeting the first preset condition, generate a distance value to obtain a distance value sequence set; generate a positioning result sequence set; generate a reliability index value set and a positioning result maximum set; generate Identify the quality index value; match the lane line information sequence set and the map information sequence set to generate a lane probability value set; generate current lane information. This embodiment can reduce the error between the geographical position obtained by positioning and the actual geographical position, thereby reducing the positioning error rate.
Description
technical field [0001] Embodiments of the present disclosure relate to the field of automatic driving, and specifically relate to a vehicle lane-level positioning method, device, electronic device, and computer-readable medium. Background technique [0002] In today's rapid development trend of automobile industry and transportation industry, advanced assisted driving technology and unmanned driving technology have become important research and development directions. Drivers usually use navigation technology, radar technology and other positioning technologies for lane-level positioning, so as to determine which lane the vehicle is in on the current road, and provide reference for vehicle planning and decision-making modules. [0003] However, when the above method is used for lane-level positioning, the following technical problems often exist: [0004] First, the existing positioning technology is greatly affected by environmental factors, thus causing a large error betw...
