| 摘 要： | 建立了基于CCD和LahVIEW的光斑分析系统,以实时监测激光应用系统中光斑的状态.对通用图像采集卡的驱动程序进行配置以便在LabVIEW中调用.对采集到的原始图像用邻域平均法进行抑噪预处理,再用加权灰度重心法计算光斑的中心位置,用检测边缘的方法计算光斑尺寸.基于LabVIEW开发了具有独立界面的采集分析软件.

| Abstract: | A laser spot analytic system based on CCD and LabView is established to monitor the laser spot status real - time.The driver of general image acquisition card is recompiled to let itself be managed in LabVIEW.The original image is processed to suppress noise by using neighborhood averaging method. The spot's center position is calculated by weighing barycenter algorithm,and the spot size is calculated by detecting its edge.Independent acquisition and analytic software is developed with LabView. |
