SYSTEM AND METHOD FOR LIDAR-BASED VEHICULAR LOCALIZATION RELATING TO AUTONOMOUS NAVIGATION
First Claim
1. A system for use in a vehicle, the system comprising:
- one or more sensors;
one or more processors operatively coupled to the one or more sensors; and
a memory including instructions, which when executed by the one or more processors, cause the one or more processors to perform a method comprising the steps of;
capturing a current point cloud with the one or more sensors;
determining an estimated location and an estimated heading of the vehicle;
selecting one or more point clouds based on the estimated location and heading of the vehicle;
simplifying the current point cloud and the one or more point clouds;
correlating the current point cloud to the one or more point clouds; and
determining an updated estimate of the location of the vehicle based on correlation between the current point cloud and the one or more point clouds.

Abstract
A system for use in a vehicle, the system comprising one or more sensors, one or more processors operatively coupled to the one or more sensors, and a memory including instructions, which when executed by the one or more processors, cause the one or more processors to perform a method. The method comprising capturing a current point cloud with the one or more sensors, determining an estimated location and an estimated heading of the vehicle, selecting one or more point clouds based on the estimated location and heading of the vehicle, simplifying the current point cloud and the one or more point clouds, correlating the current point cloud to the one or more point clouds, and determining an updated estimate of the location of the vehicle based on correlation between the current point cloud and the one or more point clouds.
