摘要: 在分析常规利用RGB混频显示技术整合分频信号的应用效果及局限性基础上,提出将三参数小波频谱成像技术与信息融合技术结合应用来预测地质异常体空间展布的新方法。该方法首先构造三参数小波进行地震资料的频谱分解从而得到不同频率小波域的高精度地震信号。在此基础上利用基于模糊逻辑理论的信息融合算法来整合得到的分频信号,最终结果以概率的形式对地质异常体的展布特征进行精细定量刻画,实际资料的应用效果证明了该方法的有效性和实用性。Abstract: On the application effect and limitation analysis of RGB frequency mixing display technology which used to integrate decomposed spectrum signals, a new method based on the three parameters wavelet spectral imaging technology and information fusion technology is proposed to predict the geologic abnormal body space distribution. Firstly, basic wavelet is constructed by three kinds of parameters and used to transform seismic signal to get different frequency domains signals, then we integrate those signals with information fusion algorithm based on fuzzy logic theory, The finally result describes geology phenomenon more efficiently like a probability index, The actual data and application effect proved the effectiveness and practicability of this method.
