A Method for Survey of Underwater Non-Contact Deformation of Fuel Assemblies

Institute of Optics and Electronics, Chinese Academy of Sciences, Chengdu, 610209, China

摘要: 水下无接触变形测量是基于视频图像传感器与标定相结合的方法,通过5组图像传感器同步对所测目标进行视频图像摄取,经由图像处理系统处理得到格架的边缘图像,之后将其转换成视频数字信号,在计算机上模拟显示出测量结果,直观地显示组件的弯曲变形和趋势。最后通过尺寸标定对未知尺寸进行测量。

Abstract: The survey of underwater non-contact deformation is based on the combined method of the video image-sensor and calibration.After the photography of the targets by five image-sensors at the same time,the images are processed by the image processing system,to get the edge image of the fuel assembly, and then transferred to the video digital signal.The results are analog displayed on the computer,and thus the bending and its future trend of the fuel assembly can be directly displayed.The unknown dimension can be obtained by calibration.
