摘　　要：混凝土结构裂缝宽度测量对监测建筑结构的健康状态、避免混凝土结构损坏性缺陷具有十分重要的意义。本文介绍了一种手持式混凝土裂缝宽度测量系统,能够现场完成裂缝图像的自动采集、处理、存储和结果显示等功能,也可将原始图像或裂缝测量结果通过USB接口输出。实验表明,系统的测试结果与混凝土裂缝宽度检验规的测量结果相符,两者测量偏差的平均值为28μm。It is very important to measure the width of cracks in concrete for monitoring the status of buildings and avoiding fatal damages of concrete structure. In this paper, we propose a handy measuring system of crack width in concrete, which can complete optical imaging, image collecting, processing and display locally. It also can transmit data by USB later. The experiments show that the measuring results by this system are quite coincident with those by the traditional gauge and the mean error is 281μm.
