Title:
LANE LINE DETECTION METHOD AND LANE LINE DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/183408
Kind Code:
A1
Abstract:
The present application provides a lane line detection method and a lane line detection apparatus, which can be applied to the field of autonomous driving or intelligent driving. Said method comprises: acquiring echo data of the ground by means of a radar, the ground comprising a lane line; pre-processing the described echo data to obtain first data; filtering the first data to obtain second data, the second data being data having an amplitude less than a first threshold; and performing imaging processing on the second data to obtain a synthetic aperture radar (SAR) image of the lane line. The lane line detection method and the lane line detection apparatus can acquire a high-resolution SAR image of a lane line, effectively improving the accuracy of lane line detection.
