Design of Beam Profile Measurement System Based on Image Processing

For HIRFL's beam profile monitor system, a new system based on video acquisition and decoding of Windows platform was designed. In order to calculate beam parameter, a flow chart of image processing which could recognize beam spot was devised on account of open computer vision library. As a result ,it solves the problem that the original system couldn't analyze beam spot in real time. The new system can get video stream stability, possess high recognition accuracy of beam spot and compute beam parameter accurately and fast, thus improving the efficiency of beam commissioning.
