Systems and methods for aligning crowdsourced sparse map data
First Claim
1. A method of determining a line representation of a road surface feature extending along a road segment, the line representation of the road surface feature being configured for use in autonomous vehicle navigation, the method comprising:
- receiving, by a server, a first set of drive data including position information associated with the road surface feature, the position information being determined based on analysis of images of the road segment;
receiving, by a server, a second set of drive data including position information associated with the road surface feature, the position information being determined based on analysis of images of the road segment;
segmenting the first set of drive data into first drive patches and segmenting the second set of drive data into second drive patches;
longitudinally aligning the first set of drive data with the second set of drive data within corresponding patches; and
determining the line representation of the road surface feature based on the longitudinally aligned first and second drive data in the first and second draft patches.

Abstract
Systems and methods are provided for aligning crowdsourced map data. In one implementation, a method of determining a line representation of a road surface feature extending along a road segment may include receiving a first set of drive data including position information associated with the road surface feature, receiving a second set of drive data including position information associated with the road surface feature, segmenting the first set of drive data into first drive patches and segmenting the second set of drive data into second drive patches, longitudinally aligning the first set of drive data with the second set of drive data within corresponding patches, and determining the line representation of the road surface feature based on the longitudinally aligned first and second drive data in the first and second draft patches.
