Source – Velodyne. This image shows a 3D map of the surroundings of an autonomous car, constructed using lidar sensor data. The map illustrates the precision and accuracy of the lidar sensor in capturing the geometry of the environment, including buildings, roads, and other obstacles. The use of lidar sensors in autonomous cars is crucial for creating a detailed and accurate map of the car's surroundings, which is then used for navigation and localization
