One of the most important technologies behind self-driving cars is LiDAR.<\/span><\/p>\n<p><span style=\"font-size: 12pt; font-family: verdana, geneva, sans-serif;\">LiDAR sensors generate detailed 3D point clouds that help autonomous systems detect objects with high accuracy. However, raw LiDAR data alone is not enough.
