摘要
介绍一套次声波形图数字化系统。该系统以图像处理技术为基础提供次声波形图扫描,倾斜矫正,图像剪切,去除水平线和垂直线,波形跟踪等功能。其关键技术包括小波分析、图像细化和像素跟踪。该系统使用户可以用计算机处理分析记录在图纸上的次声波形,使次声研究更加快捷方便,为大气核爆炸监测,爆炸源定位和当量计算,地震预测预报等研究提供一种先进的次声数据分析和管理方法。
An Infrasound Waveform Digitization System (IWDS) was introduced in detail in this paper. There are some functions in this system, such as scanning, rotating, image clipping, cleaning horizontal and vertical lines, wave tracking, etc. based on some algorithms of image processing. The key techniques includes wavelet analysis, image thinning, pixel tracing in this system. With this system, it is possible to analyze historical infrasound drawing recorded in paper by using computer. Application of IWDS will be of help to the progress in nuclear explosion monitoring in the atmosphere, locating sources, estimating explosion energies, earthquake prediction,geophysical researches.
