The invention relates to the technical field of vehicle positioning systems, and discloses a vehicle visual positioning system based on a specific scene, including: a parking lot, a vehicle detection unit, a scene database, an image acquisition unit, and a server. The server is equipped with a target parking space configuration module, The specific identification module and the pose calculation module, when the vehicle detection unit detects that the vehicle has driven into the entrance of the parking lot, the target parking space configuration module configures the target parking space for the vehicle; the server side obtains the image information to be compared from the image acquisition unit, and determines The corresponding reference image information; the pose calculation module obtains the three-dimensional position information and relative attitude information of the vehicle through the PNP pose algorithm, and calculates the position information and orientation information of the vehicle relative to the earth coordinate system according to the relative attitude information of the vehicle. Information and orientation information generate actual location information, and send the actual location information to the vehicle end.
Description
technical field [0001] The invention relates to the technical field of vehicle positioning systems, in particular to a vehicle visual positioning system based on a specific scene. Background technique [0002] Self-driving car (Self-driving Car), also known as unmanned vehicle, computer-driven vehicle, or wheeled mobile robot, is an intelligent vehicle that realizes unmanned driving through a computer system. With the popularization of self-driving vehicles, self-driving vehicles can be used as taxis or public transportation. When passengers use self-driving vehicles, they need to input their destinations. The self-driving vehicles generate driving routes based on the current location and destination, and follow the generated driving route. [0003] When the car enters the parking lot, due to the complex environment of the parking lot, it takes a lot of time for the vehicle to find a parking space by itself. In some scenarios in the field of autonomous driving, it is necess...
