The application discloses a vehicle positioning calibration method and device. The Internet of Vehicles server obtains the vehicle identification information of the first vehicle entering the identification area and the positioning information of at least one vehicle passing through the positioning line; according to the identification collection time and location collection time, determine the first vehicle corresponding to the vehicle identification information of the first vehicle and send the positioning information to the Internet of Vehicles terminal; the Internet of Vehicles terminal calibrates the position of the first vehicle according to the positioning information. With the solution of this application, the Internet of Vehicles server calibrates the position of the vehicle in the sheltered environment, and sends positioning information to the Internet of Vehicles terminal, and the Internet of Vehicles terminal calibrates the position of the vehicle itself according to the positioning information, so that a high-precision sheltered environment can be realized Vehicle positioning in .
Description
technical field [0001] The present application relates to the field of Internet of Vehicles, in particular to a vehicle positioning calibration method and device. Background technique [0002] During the driving process of the car, it is necessary to keep paying attention to the surrounding environment in order to make corresponding decisions and adjust driving behavior to cope with changes in the environment. A human-driven vehicle requires the driver to keep an eye on their surroundings. During the autonomous driving phase, the task of paying attention to the surrounding environment is transferred to the on-board computer. The on-board computer uses on-board sensors to complete the detection of the surrounding environment, such as lidar, camera, ultrasonic radar, millimeter wave radar, etc. However, these sensors have certain limitations, such as limited straight-line detection distance, inability to perceive road conditions with occlusions, and perception accuracy will ...
