Abstract

The invention discloses an identification method, device and system for highway lanes. The method comprises the steps that the total lane number corresponding to the current position of a vehicle is acquired; based on image data in front of the vehicle, lane line information of the lanes adjacent to the vehicle in the left-right direction is determined; based on the lane line information and the total lane number, the current lane of the vehicle is determined. According to the identification method, a high-precision positioning system is not needed, the method cannot be limited by influence ofthe weather and the surrounding environment of the vehicle on satellite signals, in this way, by identifying the lane lines in the image data, the current lane of the vehicle is determined, and accordingly the accuracy of judging the current lane of the vehicle is improved.

Description

Technical field [0001] The invention relates to the technical field of intelligent driving, in particular to a method, device and system for identifying highway lanes. Background technique [0002] At present, in order to determine which lane the vehicle is on the highway, it is usually necessary to configure the vehicle with high-precision differential RTK (Real-time kinematic) GPS (Global Positioning System) or GPS+IMU (Inertial measurement unit, inertial measurement unit). ) Integrated navigation and positioning system. [0003] However, due to the weather and the surrounding environment of the vehicle, such as rainy days, buildings, tunnels, flyovers, etc., where the satellite signal is blocked, the positioning signal is easy to lose. Even the high-precision positioning system cannot accurately determine the current lane of the vehicle. Summary of the invention [0004] In view of this, the present invention provides a road lane recognition method, device and system to solve th...
