直接写位图实现探地雷达数据显示研究

Research on the Method of Writing BMP in Display GPR Data

有效提高探地雷达 (简称GPR)数据的色谱显示速度是GPR软件开发的一个重要项目。由文件头、位图信息头加位图数据组的BMP位图记录格式与由文件头加道数据组成GPR数据记录格式有很强的相似性。本文利用这种相似性 ,提出了一种有效提高GPR数据显示速度的方法。该方法利用文件头和必要的文件信息生成位图信息 ,然后完成GPR数据到位图数据的变换 ,最后通过位图的显示来完成GPR数据的显示。这种方法减少了对磁盘的访问次数 ,数据变换在内存中完成 。

Finding an efficiency method to display GPR’s data for development of GPR software is an important part. Comparing BMP file to GPR file, we find they are comparability. For BMP file includes three parts: file head, info head and data. GPR file includes two parts: GPR’s head and scan data. an efficiently method is given by this similar. The method utilize file head and essential document information to obtain Bitmap message, and then transform from GPR data to Bitmap, At last attain to the display of GPR data. This method decrease to visiting frequency to disk, data transforming accomplish in memory.
