Abstract

The present application describes a polarimetric multifunctional LiDAR system adapted to perform ranging and polarimetric measurements for monitoring the road, by recognizing its type, its condition, uneven pavements, oil or chemical spills, road marking and obstacles or any other foreigner elements on the road, among others, in automotive applications and monitoring stations. By combining polarimetric measurements, i.e., some, or all, Stokes parameters of light return from the road and/or Mueller matrix elements of the illuminated area, with Artificial Intelligence, the polarimetric multifunctional LiDAR system is able to add a new functionality to conventional LiDAR sensors that allows for monitoring the road. The multifunctional LiDAR system comprises an emission system and a detection system, both controlled by a control and data acquisition system, and with a data processing system for computing range information and road monitoring.
