The invention provides a system and a method for generating basic information for positioning and a self-positioning judgment device. The positioning basic information generation system comprises an information supply device and a calculation device, the information supply device identifies respective object positions and object types of a plurality of reference objects and generates respective reference unique feature values of the plurality of reference objects according to the object positions and the object types, and the calculation device generates positioning basic information according to the plurality of reference unique feature values. The self-positioning judgment device identifies the object position and the object type of the current object, generates a current unique characteristic value of the current object according to the object position and the object type, and determines the position of the self-positioning judgment device according to the current unique characteristic value, the basic information for positioning and the distance and the angle between the self-positioning judgment device and the current object.
Description
technical field [0001] The present invention relates to a positioning system, method, and device, in particular to a system for generating basic information for positioning, a method for generating basic information for positioning, and a self-positioning judgment device. Background technique [0002] In order to meet the positioning accuracy requirements of autonomous driving technology, the existing positioning technology can use the optical radar sensor to sense the depth information of the traffic scene (such as: point cloud map), and through various algorithms (such as: normal distribution Transformation (Normal Distributions Transform, NDT) algorithm), and the depth information to generate fine basic information for positioning. However, due to the huge data volume of the existing basic information for positioning, the memory usage of the terminal device that needs its own positioning function is greatly increased, and the cost required for updating the basic informati...
