Pinpointing vehicles with high precision under adverse weather conditions

Friday, June 24, 2016 - 08:51 in Physics & Chemistry

During a mid-March snowstorm, researchers from MIT Lincoln Laboratory achieved real-time, nighttime, centimeter-level vehicle localization while driving a test vehicle at highway speeds over roads whose lane markings were hidden by the snow. The sport utility vehicle used in the demonstration was equipped with a system that employs a novel ground-penetrating radar technique to localize the vehicle to within centimeters of the boundaries of its lane. The technique could solve one of the problems limiting the development and adoption of self-driving vehicles: How can a vehicle navigate to stay within its lane when bad weather obscures road markings?
