| 摘 要： | RIS-2K探地雷达数据结构一直不公开,给利用RIS-2K雷达实测数据带来了极大的困难。为此,对RIS-2K探地雷达数据进行了分析与多方测试,基本摸清其数据结构,并编程实现了对RIS-2K探地雷达数据的读取。在常规可视化方法基础上,应用GPU并行技术实现了RIS-2K探地雷达数据快速可视化,有效解决了常规可视化速度慢及界面冻结问题,满足了对实测探地雷达资料进行实时处理解释工作的需要。试验结果证明了该方法的正确性和有效性。

| Abstract: | RIS-2K＇s data structure has been open to public and it results in great difficulties for in-depth study including further processing and interpretation of RIS-2K data. Based on RIS-2K data analysis and some tests, the data structure of RIS-2K has been made clear almost and its data may be read out. Based on conventional visualization methods, by using GPU parallel computing technology, a fast visualization method of GPR data has been implemented. It is proven to be an effective solution which overcomes problems such as slow visualization and interface freezing, and meets the requirements of real-time processing and interpreting of GPR data. The experimental results demonstrate the accuracy and validity of this method. |
