Survey on Lidar Sensing Technology for Vehicular Networks

Object detection systems are the principal pillar in various safety applications in the transportation field; various sensors can be deployed to detect and track moving objects and obstacles. In this context, LiDAR technology has shown its effectiveness. In this work, we survey LiDAR technology focusing on its functioning, sensor types and application fields. In particular, we point out its use in the vehicular field and outline the different steps followed by LiDAR-based object detection approaches.
