This article studies the identification technology of control rod drive mechanism nozzle in nuclear power plants based on OpenCV.It is of great significance to use machine vision technology to achieve automatic identification of control rod drive mechanism(CRDM)nozzle during the in-service inspection process of the reactor pressure vessel head in nuclear power plants.This study uses the OpenCV computer vision library and preprocesses the images using grayscale processing and filtering.The recognition of the nozzle is achieved through the Hough transform algorithm,in order to improve the detection efficiency of the reactor pressure vessel head inspection,shorten the detection time,and provide effective reference for the automation control of the reactor pressure vessel head inspection system.
