摘要
介绍一套新的地磁图纸数字化系统(GeomagneticDrawingDigitalizationSystem,GDDS),该系统以图像处理技术为基础提供图纸扫描,倾斜矫正,图像剪切,等比例拉伸,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,图像细化和象素跟踪.该系统使用户可以用计算机处理分析记录在图纸上的地磁波形,使地震研究更加快捷方便,为地震预测预报工作提供了一个有效的工具.
In this paper, a geomagnetic drawing digitization system, "Geomagnetic Drawing Digitalization System", was introduced. In this system, we provided some functions, such as scanning, rotating, image clipping, geometric proportion scaling, cleaning horizontal and vertical lines, wave tracking, etc. based on some algorithms of image processing. The key techniques in this system includes wavelet analysis, image thinning, pixel tracing. With this system, it is possible to analyze historical geomagnetic drawing recorded in paper by using computer. Application of this system will be of help to the progress in earthquake prediction and seismological researches.
