Embodiment Construction

[0034] For ease of understanding, the following explanations will be given to the specific concepts and terms involved in the embodiments of the present application.

[0035] (1) Global pose

[0036] The global pose can also be called absolute pose, which refers to the position and pose of an object in a reference coordinate system. The reference coordinate system can be a multi-dimensional coordinate system, and the multi-dimensional coordinate system includes a coordinate system with multiple dimensions, such as a two-dimensional coordinate system, a three-dimensional coordinate system and other multi-dimensional coordinate systems, and specifically can be a geodetic coordinate system, a universal transverse Mercator ( universaltransverse mercartor, UTM) grid system (grid system) and so on.

[0037] The position of the object can be represented by the coordinate values ​​of the coordinate axes in the coordinate system. The same object may have different coordinate values ​...

Abstract

A vehicle positioning method, device, controller, smart car and system are used to solve the problem of vehicle positioning in the case of weak or no GPS signal. The method for vehicle positioning includes: acquiring a first relative pose between the first vehicle and the object being helped and a global pose of the object being asked for help, and calculating the global pose of the first vehicle according to the first relative pose and the global pose.

Description

[0001] This application claims the priority of the Chinese patent application with the application number of 202010038272.6 and the application title of "Method, Device, System and Smart Vehicle for Smart Vehicle Positioning" filed with the China Patent Office on January 14, 2020, the entire contents of which are by reference Incorporated in this application. technical field [0002] The present application relates to the field of intelligent driving, and in particular, to a method, device, controller, intelligent vehicle and system for vehicle positioning. Background technique [0003] Global Positioning System (Global Positioning System, GPS) has the characteristics of good performance, high precision and wide application, and is the most commonly used navigation and positioning system so far. At present, the application of GPS in the field of vehicle positioning has been extremely extensive. The application of GPS in vehicles can achieve the goals of navigation and posit...
