Abstract
Disclosed embodiments include a driverless vehicle, and a method, an apparatus and a system for positioning a driverless vehicle. In some embodiments, the method includes: acquiring first laser point cloud reflection value data matching a current position of the driverless vehicle; converting the first laser point cloud reflection value data into laser point cloud projection data in a horizontal earth plane; determining a first matching probability of the laser point cloud projection data in a predetermined range of a laser point cloud reflection value map by using a position of a predetermined prior positioning position in the laser point cloud reflection value map as an initial position; and determining a position of the driverless vehicle in the laser point cloud reflection value map based on the first matching probability. The implementation can accurately position the current position of the driverless vehicle.
