摘要
本文提出了一种新的提取非金属管ＧＰＲ图像信息的方法。把ｆＢｍ模型的分形技术引进ＧＰＲ资料处理中，采用ＳＲＡ算法进行ＧＰＲ剖面分维计算。理论模型计算表明这是一种提取非金属管ＧＰＲ图像的有效方法，其效果远比常规方法处理的好。运用这一技术对工程实例进行处理，取得了十分显著的效果。
ion method for non-metallic pipeline GPR image is recommended here. The fractal technology of the fBm model has been introduced into the processing of the GPR data, and established the fBm model of the GPR. Adopting SRA method we can calculate the fractal section. The theoretical model computation shows that it is an extremely effective method for non-metallic pipeline GPR image abstraction, and its results are better than those from routine processing method. At last we process engineering example with the technique and get at remarkable effectiveness.
