Abstract

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.
