Rainy Season Driving Without Worry? Unveiling the All-Weather Perception Capabilities of Huawei’s Automotive Lidar Accessories! During rainy season driving, challenges such as drastically reduced visibility and fluctuating target reflectivity are met by Huawei’s automotive lidar accessories through multi-dimensional technological breakthroughs, providing critical support for safe driving in wet conditions.
Huawei’s LiDAR employs a high-dynamic-range receiving array and adaptive signal enhancement algorithms to penetrate rain curtains and accurately capture target features. By dynamically adjusting gain thresholds, it identifies low-reflectivity objects—such as traffic signs on flooded roads or licence plates with diminished reflectivity—even in heavy rainfall.
Combined with intelligent noise suppression technology, the system automatically filters scattered signals generated by raindrops, ensuring point cloud data purity. In torrential rain scenarios where traditional sensors may produce false detections due to raindrop interference, Huawei’s LiDAR significantly reduces false alarm rates through a time-domain/spatial-domain joint filtering algorithm.
To address detection range degradation in foggy or rainy conditions, Huawei employs distributed multi-wavelength laser emission technology. Its transmission module integrates multiple laser sources, dynamically switching to the optimal operating wavelength. In light fog, the system automatically activates short-wavelength lasers to enhance the scattering cross-section, leveraging their penetrative advantage to maintain long-range detection capability.
Huawei’s LiDAR forms multi-modal perception redundancy with cameras and millimetre-wave radar. When heavy rain obscures camera visibility, the LiDAR provides three-dimensional spatial data. Through dynamic target fusion with millimetre-wave radar, it enables precise classification and trajectory prediction of vehicles, pedestrians, and obstacles.
