摘　　要：提出了基于图像识别技术的嵌入式桥梁拉索表面损伤检测方法,并进行了技术实现。检测系统采用并行式图像采集阵列,同一时刻将采集到的拉索表面一周的视频图像数据实时送入TMS320DM642进行图像处理,以此为基础进行缺陷判断和存储。该系统为实现实时、准确的拉索缺陷识别提供了解决方案。The cable detection is an important part of the maintenance of cable-stayed bridges and suspension bridges. The embedded surface damage detection system of the bridge cable based on image recognition is introduced. Depending on the concurrent sensor array, the surface image data of the bridge cable are collected and sent to TMS320DM642 for image cropping, pretreating, rectifying image projection, and damage detecting and saving. The system provides an effective way to exactly detect the surface damages of the bridge cable in real time.
