Outdoor Low-Speed Unmanned Vehicle: Forward Blind Spot Suppression and 3D Environment Perception

Low-speed autonomous vehicles, such as unmanned delivery vehicles and unmanned sweepers, typically operate on outdoor, unstructured roads. Although the main lidar mounted on the roof has a long detection range, it creates a significant near-field blind spot beneath the vehicle’s front end. As a result, the main lidar often struggles to detect low-lying obstacles—such as curbs, pets, or traffic cones—as well as road surface potholes (negative obstacles). Moreover, intense sunlight outdoors places extremely high demands on the sensors’ anti-interference capabilities; ordinary depth cameras tend to fail under strong lighting conditions.
