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.
