Image Processing Algorithm for Area Array CCD Based on Vacuum Laser Alignment Monitoring System

The image processing algorithm for area array CCD are studied based on characteristics of the vacuum laser alignment monitoring system.Firstly,the target image is compared with the background image and processed by filtering algorithm.Secondly,the edge recognition algorithm by subarea scanning is presented to determine the facula contour.Finally,the facula energy center is found out through the centroid method.The practical application shows that the methods and algorithms for the image processing of the vacuum laser alignment monitoring system can meet requirements of practical engineering safety monitoring.
