Embodiment Construction

[0031] A ground-penetrating radar gray-scale stacking image recognition method, using the Butterworth band-stop filter to clear the gray-scale stacking image, and using the prewitt operator to detect the edge of the gray-scale stacking image, through Fourier transform and convolution Product operation for image feature target recognition.

[0032] Described ground penetrating radar comprises data processing module 5, data recognition module 6, display module 7;

[0033] The GPR also includes a detection module 1, an information receiving module 2, an information storage module 3, an information management module 4,

[0034] The detection module 1 uses a trigger pulse forming circuit to trigger the avalanche transistor 2N2219 to quickly pressurize, thereby generating the required high-voltage electromagnetic pulse. Depending on the pulse width, antennas with different frequencies can be selected, and antenna pulse integrated modules such as BS-357 can also be used directly. B...

Abstract

The invention relates to a gray scale accumulation image identification method of a ground penetrating radar. The method comprises: carrying out gray scale accumulation image sharpening processing byusing a Butterworth band elimination filter, carrying out gray scale accumulation image edge detection by using a prewitt operator, and carrying out image feature target identification through Fouriertransform and convolution operation. According to the grayscale accumulation image recognition method of the ground penetrating radar, the intuition of manual image recognition and the convenience ofdirectly analyzing and displaying the recognition result by the system background can be effectively realized, and the efficiency and accuracy of the ground penetrating radar in application are improved.

Description

technical field [0001] The invention relates to the technical field of ground-penetrating radar image recognition, in particular to a method for recognizing a grayscale accumulation image of a ground-penetrating radar. Background technique [0002] With the rapid development of my country's electric power industry, electric power construction has become more and more frequent. During the construction process, it is necessary to confirm the geological structure, underground cables and pipelines, so as to ensure the smooth progress of the construction. Ground-penetrating radar is an effective means of detecting underground targets developed in recent decades, because it is a non-destructive technology, and has the advantages of fast detection speed, continuous detection process, high resolution, convenient and flexible operation, and low detection cost. Advantages, the application is gradually widespread. At present, most of the detected images are gray-scale stacked images. ...
