实时全息干涉视频图像自动化处理及应用研究

Study of automatic digital video image processing for real-time holographic interferometry

研究了实时全息干涉条纹视频图像计算机自动处理技术。采用Delphi可视化软件为开发工具,在Win dows环境下播放实时全息干涉图像,并同时获取在播放窗口中任意指定的灰度值、自动描绘灰度 时间以及位移 时间曲线。对测试原理和图像去噪、曲线平滑等关键处理技术进行了介绍。通过对微电子产品热变形研究的实例分析,显示了该自动处理软件的操作便捷、实用和先进性。

An automatic digital video image processing software for analysis of the realtime holographic interference fringe was developed. The Delphi visual software development platform was used and windows API was adopted to get the prayvalue of the random positions that the mouse clicked on. A neighborhood field average filtering method is adopted to eliminate the image's noise, and the averagesmoothnesscurve's method was used to smooth the curve of grayvalue varied with time. The curve of the prayvalue varied with time and the curves of outofplane displacement varied with time were drawn automatically. The dynamic digital processing techniques were discussed.
