The method of detecting the edge of wavelet transform in ultrasonic imaging logging images was studied. The principle of wavelet transform edge detection is introduced. The algorithm of edge detection based on wavelet transform modulus maxima in ultrasonic imaging logging is introduced. Finally, the application examples are given. Practice shows that using wavelet transform to detect the edge of ultrasonic imaging logging method can effectively make up for the deficiencies of the traditional edge detection algorithm and effectively reduce the noise while improving the accuracy of detecting small edge components. This method can detect the geologic features with different details from the edge images at different scales. The results at small scales can be used to analyze the fine structure of geologic bodies in ultrasonic imaging logging images. The results of large-scale detection It can be used to analyze the overall structure of geological body of ultrasonic imaging logging images
