Abstract

Disclosed herein are a lane estimation apparatus and method. The lane estimation apparatus includes a camera unit which captures an image in front of a vehicle, a radar unit which senses a plurality of stationary objects in front of the vehicle, and a lane estimation unit which detects a lane through the image captured by the camera unit, generates an imaginary lane joining a plurality of stationary objects next to a road among the stationary objects sensed by the radar unit, determines whether the generated imaginary lane is valid based on a distance between the detected lane and the generated imaginary lane, generates, when the imaginary lane is valid according to the determined result, a final lane based on the detected lane and the imaginary lane, and recognizes the generated final lane as a driving lane of the vehicle.

Description

technical field [0001] Embodiments of the present invention relate to a lane estimation device and method capable of more accurately estimating a driving lane. Background technique [0002] In general, LKAS (Lane Keeping Assist System, Lane Keeping Assist System) is a system that generates auxiliary steering torque with the help of lane information from the camera when the vehicle deviates from the lane during driving to facilitate driving. [0003] However, due to direct sunlight (backlight), dust on the road, etc., the camera will not recognize the lane or misrecognize the state, and the lane keeping assist function of the camera is limited due to the time delay for recognizing the lane. [0004] In addition, LKAS is sensitive to changes between short-distance lanes and long-distance lanes. Therefore, the performance of LKAS is limited because it takes a long time for LKAS to identify lanes. Contents of the invention [0005] Therefore, one aspect of the present invent...
