Analysis of Automotive LiDAR Technology and Its Integration with Vehicle Headlights
With the development of autonomous driving technology,in order to achieve higher safety redundancy for vehicle occupants,vehicles have put forward high-perception requirement for environment perception.As a new type of vehicle-mounted high-perception three-dimensional perception sensor,LiDAR has become a key sensor for realizing high-level autonomous driving.LiDAR uses the time-of-flight method to sense the spatial coordinates,reflectivity and other information of objects.Based on several years of technology iteration,mass production applications have been achieved.Compared with millimeter-wave radar,cameras and ultrasonic radars,LiDAR has larger power consumption and volume,and its current installation location is usually on the roof of the vehicles.This installation location will affect the appearance and wind resistance of the vehicle,and integrating LiDAR into vehicle headlights has become a technical solution to solve the installation location of LiDAR.In this paper,based on the current development trends of LiDAR and vehicle headlights technology,we conduct a technical analysis of vehicle LiDAR and its headlights integration,and the feasibility of integrating LiDAR into car lights.
