Real Time Vision System for the Test of Steam Generator in Nuclear Power Plants Based on Fuzzy Membership Function

퍼지 소속 함수에 기초한 원전 증기발생기 검사용 실시간 비젼시스템

In this paper it is proposed a new approach to the development of the automatic vision system to examine and repair the steam generator tubes at remote distance. In nuclear power plants workers are reluctant of works in steam generator because of the high radiation environment and limited working space. It is strongly recommended that the examination and maintenance works be done by an automatic system for the protection of the operator from the radiation exposure. Digital signal processors are used in implementing real time recognition and examination of steam generator tubes in the preposed vision system, Performance of proposed digital vision system is illustrated by experiment for similar steam generator model.
