Abstract

Abstract

The reactor core detector assemblies of HPR1000 reactor need to be removed and replaced after their life cycle expires. Due to the large deviation of the detector assemblies themselves and other factors, the theoretical coordinates during installation cannot be directly used as the positioning coordinates during the removal of the detector assemblies. In this paper, an algorithm for image positioning of core detector assembly is developed based on machine vision software Halcon. The algorithm uses the principle of template matching to search in the images of the detector assemblies captured by the camera to obtain the exact coordinates of the detector assemblies. Experiments show that the algorithm has high positioning accuracy and can meet the requirements of the image positioning algorithm for the removal of the detector assemblies.
