Title:
POSITIONING METHOD, DEVICE, EQUIPMENT, AND SYSTEM, MEDIUM, AND AUTONOMOUS VEHICLE
Document Type and Number:
Japanese Patent JP2023047329
Kind Code:
A
Abstract:
To provide a positioning method, device, equipment, and system, a medium, and an autonomous vehicle, and to apply them to cloud computing regarding a positioning technique field, especially automatic driving and an artificial intelligence technique.SOLUTION: According to a specific embodiment, a current key point in point cloud data of a current frame and a point cloud distribution feature of the current key point are determined based on point cloud data of a current frame in a driving environment collected by a positioning wait terminal, a target key point that matches the current key point is selected from reference key points on the basis of the point cloud distribution feature of the current key point and a point cloud distribution feature related to the reference key point on a global positioning map, and current pose data of the positioning wait terminal are determined on the basis of reference pose data related to the target key point. According to the art in the present disclosure, precise positioning for the positioning wait terminal can be realized under a driving environment without GPS or with a weak GPS signal.SELECTED DRAWING: Figure 1A
