Abstract

The invention discloses a method and a device for determining a target lane. The method includes the following steps: performing image acquisition on the running pavement of a vehicle to obtain imageinformation of the running pavement; identifying first lane information of the running pavement from the image information, wherein the first lane information includes a first lane for indicating thelane position of the vehicle on the running pavement and the characteristics of the first lane; and performing characteristic matching on the characteristics of the first lane and the characteristicsof at least one second lane in a map containing the running pavement to determine the target lane of the vehicle in the map, wherein the at least one second lane and the characteristics of the at least one second lane are obtained from the map, and the at least one second lane includes the target lane. The technical problem of high investment cost during accurate positioning of the vehicle is solved in the invention.

Description

Technical field [0001] The present invention relates to the field of automatic driving, in particular to a method and device for determining a target lane. Background technique [0002] Driverless cars, also known as self-driving cars, are smart cars that perceive the road environment through the on-board sensor system, automatically plan driving routes, and control the vehicle to reach a predetermined target location. In related technologies, driverless cars can use the following positioning The system or positioning method locates the position of the vehicle: [0003] GPS: GPS is the abbreviation of English Global Positioning System (Global Positioning System). GPS is a omni-directional, all-weather, all-time, high-precision satellite positioning and navigation system. [0004] BDS: BDS is the abbreviation of BeiDou Navigation Satellite System in English, and is a global satellite navigation system developed by China. It is the third mature satellite navigation system after the ...
