Abstract

The invention discloses an igneous rock stone three-dimensional modeling method based on a GprMax open source program, and the method comprises the steps: building a small stone which is composed of igneous rock and has a large impact on the detection of a non-metallic landmine through a mixed medium model based on the GprMax open source program; the beneficial effects of the invention are that the method achieves the three-dimensional modeling of igneous rocks, provides reliable training data for a nonmetal landmine target detection method based on the deep convolutional neural network, and achieves the accurate analysis and interpretation of a nondestructive detection result of the ground penetrating radar.

Description

technical field [0001] The invention relates to a three-dimensional modeling method for igneous rock blocks, in particular to a modeling method for igneous rock blocks based on the GprMax open-source program, and belongs to the physical modeling technology for electromagnetic wave non-destructive detection in the field of geophysical exploration. Background technique [0002] Since the end of World War II, there are still a large number of landmines on the shallow surface that have not been discovered and cleared. Among them, traditional metal mines are generally anti-tank mines, which are less harmful to people and easy to detect. The anti-personnel landmines that exist in large numbers are usually non-metallic landmines. Traditional detection methods are difficult to detect such landmines, and the false alarm rate is high, which may easily cause accidental injury to civilians. Ground penetrating radar (GPR) technology is a non-destructive testing method that determines the...
