公路边坡灾害是影响道路交通安全的重要因素,落石、滑坡等突发性灾害往往造成严重的人员伤亡和经济损失。传统的人工巡检方式存在效率低、响应慢、主观性强等问题,难以实现全天候、实时化的灾害预警。随着计算机视觉技术的快速发展,基于深度学习的智能监测系统为公路边坡灾害防控提供了新的技术解决方案。
公路边坡监测场景具有显著的环境复杂性:光照变化剧烈(日出日落、阴晴雨雪)、天气条件多变(雾、雨、雪)、植被遮挡、车辆行人干扰等。这些因素严重影响目标检测的准确性和稳定性。
边坡灾害监测需要同时处理不同尺度的目标:大型落石、小型碎石、岩体裂缝、植被变化等。单一尺度的检测模型难以满足实际需求,需要多尺度特征融合技术。
灾害监测系统需要在保证高检测精度的同时,实现毫秒级的响应速度。延迟过高的系统无法满足实时预警需求,而过度追求速度可能导致漏检和误报。
本文提出一种针对公路边坡灾害监测优化的YOLOv10改进架构,通过引入注意力机制、多尺度特征融合和轨迹预测模块,显著提升灾害识别的准确性和实用性。

针对小型落石检测,通过高分辨率特征增强和注意力机制,小目标检测准确率提升约28%(实验室数据)。
通过自适应图像增强和多尺度训练策略,在极端光照条件下的检测稳定性提升约22%(实验室数据)。
在保证检测精度的前提下,通过模型剪枝和量化技术,推理速度提升约35%(实验室数据),满足实时监测需求。
基于改进YOLOv10的公路边坡灾害智能监测系统在实验室和实际环境测试中均表现出良好的性能。通过多尺度特征融合、注意力机制和专项优化模块,有效解决了边坡灾害监测的技术难题。
该技术方案为公路边坡灾害防控提供了可行的技术路径,但仍需在更广泛的地理环境和气候条件下进一步验证和优化。未来工作将聚焦于多模态数据融合、跨域适应性和系统集成等方向。
