摘　　要：针对道路超高车辆频繁碰撞桥涵,对行车安全构成严重威胁的现状,提出一种创新性解决方案。设计并实施一种基于单线激光雷达的自适应车辆高度检测算法。该算法利用激光二维扫描技术自动辨识地面并准确计算车辆高度,实验显示,算法能够将车辆高度的检测误差控制在±2 cm之内,且在连续监测中,实现了100%的检出率和0%的误报率。一旦发现超高车辆,系统立即输出信号,供视频追踪、证据保存或触发声光报警等后续措施使用。这些成果证明了该算法在车辆限高领域的高度精准性和可靠性,同时凭借其稳定性、适应性、低成本和易维护性,在该领域具有重要的应用价值。To address the pressing issue of frequent collisions between over-height vehicles and bridges,which pose significant road safety hazards,this study introduces an innovative solution.We have developed an adaptive vehicle height detection algorithm based on single-line LiDAR technology.Utilizing two-dimensional laser scanning technology,the algorithm automatically identifies the ground and accurately measures vehicle height.Experiments demonstrate that the algorithm effectively limits vehicle height measurement errors to within±2cm,achieving a 100%detection rate with 0% false positives during continuous monitoring.Upon detecting over-height vehicles,the system immediately signals for video tracking,evidence preservation,or activation of audio-visual alarms.These results confirm the algorithm's high precision and reliability in the vehicle height restriction field,along with its stability,adaptability,low cost,and ease of maintenance,thus highlighting its considerable value in this field.
