精准环境感知对高级驾驶辅助系统(ADAS)至关重要。激光雷达(LiDAR)在ADAS中扮演关键角色,能可靠检测障碍物,保障行车安全。现有研究显示,根据环境特征自适应调节激光雷达的分辨率和探测范围可提升机器感知性能。然而,当前针对ADAS的自适应激光雷达方法尚未探索将车辆感知与人类驾驶员视觉能力结合的潜力,而这可能进一步提升检测效果。本文提出一种新系统,通过自适应调整激光雷达特性以匹配驾驶员视觉感知,增强对人眼视野外区域的探测。我们在虚拟环境CARLA中构建了原型系统,实时获取驾驶员注视数据,识别其关注区域,从而在驾驶员未注意的周边区域动态提升激光雷达的探测范围和分辨率。仿真结果表明,相较于基准独立激光雷达,在雾天等挑战性条件下,该注视感知型激光雷达显著提升了检测性能。所提出的混合人机感知方法为实时驾驶场景中的ADAS应用提供了更优的安全性与情境意识。
原文摘要 · Abstract (English)
Accurate environmental perception is critical for advanced driver assistance systems (ADAS). Light detection and ranging (LiDAR) systems play a crucial role in ADAS; they can reliably detect obstacles and help ensure traffic safety. Existing research on LiDAR sensing has demonstrated that adapting the LiDAR's resolution and range based on environmental characteristics can improve machine perception. However, current adaptive LiDAR approaches for ADAS have not explored the possibility of combining the perception abilities of the vehicle and the human driver, which can potentially further enhance the detection performance. In this paper, we propose a novel system that adapts LiDAR characteristics to human driver's visual perception to enhance LiDAR sensing outside human's field of view. We develop a proof-of-concept prototype of the system in the virtual environment CARLA. Our system integrates real-time data on the driver's gaze to identify regions in the environment that the driver is monitoring. This allows the system to optimize LiDAR resources by dynamically increasing the LiDAR's range and resolution in peripheral areas that the driver may not be attending to. Our simulations show that this gaze-aware LiDAR enhances detection performance compared to a baseline standalone LiDAR, particularly in challenging environmental conditions like fog. Our hybrid human-machine sensing approach potentially offers improved safety and situational awareness in real-time driving scenarios for ADAS applications.
