Title: Self position estimation method for autonomous driving vehicle, system, and machine readable medium
Inventor: ZHU FAN
IPC: B60W40/00
Filed: 2019-02-04
Abstract: To determine a relative position of an autonomous driving vehicle (ADV).SOLUTION: A self-localization system determines, in an ADV, a relative position within a lane by using several sensors mounted on each location of a vehicle. Several cameras may be mounted on different locations of the vehicle to capture images with respect to surrounding environment of the vehicle. On the basis of the captured images, distance between the vehicle and edges of the lane may be determined by an image recognition process or algorithm. On the basis of the distance between the vehicle and the edges of the lane, the relative position of the vehicle within the lane can be determined. The relative position of a vehicle within the lane refers to an angle of a traveling direction of the vehicle and a longitudinal vector of a center line or a reference line of the lane, and distance between the vehicle and the center line or the reference line of the lane.SELECTED DRAWING: Figure 1
