Abstract

The invention discloses a method and a device for determining vehicle positioning information. Among them, the method can be applied to the map field, including: according to the current GPS information obtained by the GPS device on the current vehicle at the current time point, the current sensor information obtained by the inertial sensor on the current vehicle at the current time point , determine the preliminary pose of the current vehicle at the current time point, and obtain the current image captured by the camera on the current vehicle at the current time point; according to the preliminary pose, determine the target matching the current image in the offline database Historical images, and according to the target historical image, obtain a plurality of matching pairs; according to the plurality of matching pairs, determine the vehicle positioning information of the current vehicle at the current time point. The invention solves the technical problem of low vehicle positioning accuracy.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a method and device for determining vehicle positioning information. Background technique [0002] In the related art, a global positioning system (Global Position System, GPS for short) is usually used to locate the vehicle. But the GPS positioning error is large. And it is difficult to locate the vehicle in areas with weak GPS signals such as tunnels and mountainous areas. Combined with an inertial sensor (Inertial Measurement Unit, IMU), it can assist in positioning the vehicle in areas with weak GPS signals, but the inertial sensor increases with time, and the positioning error increases. [0003] With the development of automatic driving technology, the requirements for the accuracy of vehicle positioning are getting higher and higher, and the current vehicle positioning technology is difficult to meet the needs of automatic driving. The positioning accuracy of lidar...
