What role do LiDAR sensors play in vehicle systems?
What role do LiDAR sensors play in vehicle systems?
Lidar sensors are an active, modern optical detection technology widely applicable across various sectors of society—they represent a highly advanced environmental sensing tool. As vehicle intelligence continues to advance rapidly, highly sophisticated, autonomous, and connected smart vehicles will see widespread adoption. In this context, lidar sensor technology plays a crucial role in intelligent vehicle systems. This article will explore the specific applications of lidar sensors within automotive systems.
1. High-Precision Vehicle Positioning
With the help of positioning systems, vehicle systems can make decisions by obtaining real-time location data. However, the positioning method can be affected by signal interference, especially when passing through urban buildings or tunnels, where signals are prone to interruption. To achieve precise localization, LiDAR compares the vehicle’s initial position with high-definition map information.
(1) The vehicle's initial position is provided by sensors such as inertial navigation systems, the Global Positioning System, and wheel speed sensors;
(2) Stop feature extraction on the partial point cloud data from the LiDAR, separate the initial positions to obtain vector features in the global coordinate system.
(3) By aligning vector features with high-definition map data, we can accurately determine the vehicle’s position. As a result, LiDAR demonstrates clear advantages over other in-vehicle sensors in terms of positioning accuracy and stability.
2. Obstacle Recognition and Target Tracking
Lidar can stop real-time scanning without relying on lighting, offers a scanning angle of up to 360°, and requires relatively low computational power.
During scanning, obstacle recognition—such as vehicles, pedestrians, and barriers—is first paused to accurately determine the spatial location of the obstacle. For obstacle classification and tracking, the process begins with point cloud segmentation and association, ensuring that consecutive frames can be linked to the same object before proceeding with target tracking and finally outputting the tracking information.
3. Automatic Parking System
Laser radars installed on the vehicle roof or around the body can detect parking space locations, identify surrounding vehicles and other obstacles, and feed the collected data into the vehicle’s control system, providing reliable environmental information to support automated parking decisions.
4. Lane Keeping Assist System
Using LiDAR for lane detection, the Lane Keeping Assist System detects when a vehicle deviates from its estimated driving path. Through logical computations and decision-making, the system controls the vehicle to stay on the predetermined lane trajectory. This LiDAR-based lane detection method relies on the density of radar scan points. To accurately identify the desired lane lines, the system first retrieves the coordinate information of the radar scan points, converts it into a grid map, and then analyzes the point density within the grid to extract the lane boundaries—making this approach highly effective in real-time applications.
