摘　　要：桥梁裂缝几何特征的精确测定是桥梁健康监测与维护流程中的核心环节。借助对裂缝长度、宽度及面积等几何特征的细致测量,可全面评估桥梁的结构安全性能和预期使用寿命。当前,这一测定过程融入了先进的激光扫描技术、数字图像处理技术以及计算机视觉技术,这些高科技手段不仅显著提升了测量的精确度与工作效率,还实现了非接触式的监测方式,极大地降低了对桥梁结构本身可能造成的损伤风险。进一步地,通过对裂缝几何特征数据的深入分析,能够更准确地预测裂缝的扩展趋势。据此,可以制定出更科学合理的维修策略,从而确保桥梁的安全性和稳定运行。The accurate measurement of the geometrical characteristics of bridge cracks is a key step in the process of bridge health monitoring and maintenance.Using the detailed measurement of geometrical characteristics such as crack length,width and area can fully assess the structural safety performance and expected service life of the bridge.At present,this measurement process incorporates advanced laser scanning technology,Digital Image Processing technology and Computer Vision technology,and these high-technology means not only significantly improve the accuracy and work efficiency of the measurement,but also realize a non-contact monitoring method,greatly reducing the risk of damage to the bridge structure itself.Further,through the in-depth analysis of the geometrical characteristics data of cracks,the crack expansion trend can be predicted more accurately.On the basis,a more scientific and reasonable maintenance strategy can be formulated,so as to ensure the safety and stable operation of the bridge.
