摘　　要：基于数字摄影测量的基本原理，研发了一种桥梁毁伤非接触检测仪，并详细介绍了硬件系统和软件系统的组成与功能。实桥试验表明，该仪器可以测量桥梁裂缝、破损等毁伤的几何参数，具有远距离、非接触、高精度和实时性的特点，对于平时或战时毁伤桥梁的检测与评估具有重要意义。Based on the basic principle of digital photogrammetry, a kind of non-contact bridge damage detector is designed, and the composition and functions of hardware and software systems are deeply introduced. The real bridge experiment shows that the detector can measure geometric parameters of the bridge damage such as crack and breakage. And the characteristics of the detector is long distance, non-contact, high precision and real time, which have important meanings for the detection and estimation of the damaged bridge on peacetime and wartime.
