Real-time positioning method and device applied to automatic driving

Abstract

Embodiments of the invention disclose a real-time positioning method and device applied to automatic driving. The method comprises the steps of obtaining inertia measurement sensor data from an inertia measurement sensor built in a vehicle and recording a time point of obtaining the inertia measurement sensor data; when sensor data except the inertia measurement sensor data is obtained at the timepoint, positioning the vehicle according to the inertia measurement sensor data and the other sensor data; and when the other sensor data is not obtained at the time point, positioning the vehicle according to the inertia measurement sensor data. By implementing the method and device, the time point of receiving the inertia measurement sensor data can be used as a time reference, and the sensor data obtained at the time point is combined to carry out positioning, thereby improving the vehicle positioning precision.

Description

technical field

[0001] The invention relates to the technical field of automatic driving, in particular to a real-time positioning method and device applied to automatic driving. Background technique

[0002] In the existing vehicle positioning method, the built-in camera of the vehicle usually captures image information, sends the captured image information to a data processor, and then analyzes and processes the data processor to obtain a positioning result. However, it has been found in practice that the image information data is usually relatively large, and it takes a long time to transmit it to the data processor. In addition, after the image information data is transmitted to the data processor, the data processor is also very difficult to process the image information data. Time-consuming, therefore, the current vehicle position information obtained by using the camera for vehicle positioning is actually earlier than the vehicle position information long before the c...
