摘　　要：为提高突发灾害后桥梁快速评估,确保桥梁结构安全,设计了一款基于摄像机阵列的水下检测装备,以实现桥梁水下结构病害的快速精确测量。在分析水下工作环境的基础上,提出摄像机阵列的具体设计方案。为减小水下阻力,适应在浑水中近距离大视场检测,系统采用的摄像头是带照明的微型摄像机。为减小后期图像拼接的压力,本系统采用Matrox_morphis_qxt图像采集卡,配合磁盘阵列RAID系统以达到同步采集、实时传输、快速存储。最终通过图像拼接技术,恢复被测桥梁水下结构表观全貌图。To enhance bridge rapid assessment to ensure the structural safety of the bridge,after the sudden natural disasters.Design camera array underwater detection equipment in order to achieve fast and accurate measurement of the bridge underwater structures disease.In this paper,on the basis of the analysis of the underwater environment,the specific design of the camera array.In order to reduce underwater resistance to adapt in the muddy water close large field of detection,the system uses a camera with lighting miniature endoscope.In order to reduce the pressure of the image mosaic,the system uses the Matrox_morphis_qxt frame grabber,with the RAID disk array system in order to achieve synchronous acquisition,real-time transmission,fast storage.Eventually,through image mosaic technology the apparent close-up view of the measured bridge underwater structures can be restored.
