Abstract

The invention relates to an apparatus for a self localization of a vehicle. The apparatus includes a sensor unit, a landmark detector, a landmark recognizer, and a location estimator. The sensor includes at least two sensors and is configured to measure information on environment around the vehicle using each of the at least two sensors. The landmark detector is configured to detect landmark information based on data measured by each sensor. The landmark recognizer is configured to selectively combine landmark information detected based on data measurement of at least one of the at least two sensors to recognize a landmark and reflect fused landmark information to update a probability distribution. The location estimator is configured to use the probability distribution updated by the landmark recognizer to estimate a self location of the vehicle.

Description

technical field [0001] The present invention relates to a device and method for vehicle self-positioning, in particular to a vehicle self-positioning system capable of using cameras and radars to detect landmark information and selectively fusing the detected landmark information to accurately identify the position of the vehicle and the current vehicle position devices and methods. Background technique [0002] With the increasing interest in autonomous vehicles, localization methods that can accurately estimate the location of the vehicle in urban areas become more important. Autonomous vehicles drive based on precise maps. However, a precise map is useless if the driver of the vehicle does not know where the vehicle is currently located in the precise map. In recent years, people have scanned the map environment by using two-dimensional (2D) / three-dimensional light detection and ranging (LiDAR: light detection and ranging) with very high range precision, and then compar...
