本文提出的地震多尺度边缘检测技术以坎尼最佳边缘检测准则和小波变换的多分辨分析为理论基础,能在地震记录上较方便而可靠地识别地下介质的横向变化。这些横向变化包括不能用肉眼在地震同相轴上直接发现而又实际存在的隐蔽特征。对地层尖灭,透镜体、岩性变化和孔洞、裂缝发育带均可进行识别。模型计算和实际地震资料的处理结果显示该方法具有实际应用价值
The proposed multi-scale seismic edge detection technology based on Canny’s best edge detection criterion and multi-resolution analysis based on wavelet transform can identify the lateral variation of underground media easily and reliably in seismic records. These lateral variations include covert features that can not be found directly with the naked eye on the seismic events but actually exist. Extinction of the stratigraphy, lens body, lithology and holes, cracks development zone can be identified. The results of model calculation and actual seismic data show that the method has practical application value
