The technology primarily used in autonomous vehicles for navigation is LiDAR (Light Detection and Ranging). LiDAR systems use laser scanning to create high-resolution maps of the vehicle's surroundings, allowing for precise distance measurements and obstacle detection. This technology plays a vital role in enabling real-time situational awareness, facilitating safe navigation, and automating the driving process. Additionally, LiDAR data is often combined with other sensors, such as cameras and radar, to enhance the vehicle's ability to interpret complex environments autonomously.
