摘　　要：为解决人工定期跟踪观测裂缝耗时费力且易引入主观误差的问题,提出一种自动化多时态裂缝变化检测方法。通过图像配准技术处理一般相机运动图像,并采用区域减法来实现裂缝时序图像的关联分析。试验结果表明,所提方法可以较为准确地对齐裂缝,具有良好的可行性,可提高工程实际效率。To address the issue of time-consuming,labor-intensive,and prone to subjective errors in manual period⁃ic follow-up crack observations,an automatic multi-temporal crack change detection method is proposed.By em⁃ploying the image registration technique to handle images with general camera motions,the correlation analysis be⁃tween temporal crack images can be realized with the adoption of region subtraction.The experimental result shows that the proposed method enables accurate crack alignment and exhibits favorable feasibility,promising to improve the efficiency of the engineer practice.
