Title:
SYSTEMS AND METHODS FOR DETECTING ROAD MARKINGS FROM A LASER INTENSITY IMAGE
Document Type and Number:
WIPO Patent Application WO/2021/056309
Kind Code:
A1
Abstract:
A system and method for detecting road markings from a laser intensity image (102) are provided. The method may include receiving, by a communication interface (202), the laser intensity image (102) acquired by a sensor (160,S302). The method may also include segmenting the laser intensity image (102) into a plurality of road segments and dividing a road segment into a plurality of sub-images (S304). The method may further include generating a road marking image corresponding to each of the sub-images based on a semantic segmentation method using a learning model (S306) and generating an overall road marking image for the road segment by piecing together the road marking images corresponding to the sub-images of the road segment (S308).
