Abstract

Systems and method are provided for controlling a vehicle. In one embodiment, a localization method includes receiving sensor data relating to an environment of a vehicle, the sensor data including aplurality of sensor returns associated with objects in the environment, each of the sensor returns having a plurality of corresponding attributes, and constructing a first plurality of sensor data groups, each including a self-consistent subset of the plurality of sensor returns based on their corresponding attributes. The method further includes defining, for each of the first plurality of sensordata groups, a first set of features, wherein each feature is based on at least one of the corresponding attributes and each has an associated feature location, and determining, with a processor, a feature correlation between the first set of features and a second, previously determined set of features.

Description

technical field [0001] The present invention relates generally to autonomous vehicles, and more particularly to systems and methods for determining the position of an autonomous vehicle relative to its environment. Background technique [0002] An autonomous vehicle is one that is able to sense its environment and navigate with little or no user input. It does so by using sensing devices such as radar, lidar, image sensors, etc. The autonomous vehicle further uses information from global positioning system (GPS) technology, navigation systems, vehicle-to-vehicle communications, vehicle-to-infrastructure technology, and / or drive-by-wire systems to navigate the vehicle. [0003] While autonomous vehicles have made significant progress in recent years, there are still many ways in which such vehicles could potentially be improved. For example, localization (ie, determining the geographic location of a vehicle) is typically achieved via a combination of Global Positioning Syst...
