中文摘要：
在对地质异常体进行检测时,若异常体所在位置检测值的值域范围较小,则很难选择合适的配色方案将异常体突出显示出来。针对这一情况,本文提出了对不同检测值段进行区间放缩的方法突出显示异常体。该方法首先根据不同检测值段出现的频率来放缩该段的值域,再依据线性变换将检测值映射到新的值域,最后通过调色显示新检测值。通过对模型的试验以及对川东北XX区二叠系长兴组潮道和塔河YY区三叠系中油组砂体的处理,证实了该方法效果明显。
英文摘要：
It can be difficult to highlight the anomalous body by a color matching scheme in the detection for geologic anomalous body if the value range for detecting value of anomalous body is too small.Aimed at this instance,a zoom method to highlight the anomalous body for different detection value intervals was proposed in the paper.First,the value range of interval was zoomed according to the showing-up frequency of different detection value intervals,then liner transform was used to map the detection value into new value range and finally the new detection value was displayed through the color mixing.The model test and the processing result for the tidal channel of Changxin Formation of Permian in XX area of northeast Sichuan Basin,and the sand body of Triassic Zhongyou Formation of YY area in Tahe proved the effectiveness of the method.
