The invention discloses a two-dimensional 
ground penetrating radar three-dimensional imaging method based on 
MATLAB. The method comprises the following steps: S1, assembling and debugging a two-dimensional 
ground penetrating radar; S2, performing 
data acquisition on each lane in an acquisition 
route; S3, establishing a three-dimensional imaging model; S4, performing appearance optimization and 
size adjustment on the three-dimensional imaging model; S5, exporting three-dimensional data; S6, performing 
data format conversion; S7, simulating three-dimensional reflection 
voltage data; S8, settingthe colors of the maximum value and the minimum value; S9, importing the three-dimensional data into a three-dimensional imaging model to obtain a three-dimensional image; S10, performing 
slicing display on the abnormal position, and visually displaying the road deep layer diseases. Through the establishment and optimization of the three-dimensional model, the imaging model capable of accommodating the three-dimensional 
radar data is formed; after the simulated three-dimensional data is imported, three-dimensional 
radar imaging is realized, and an image 
cutting function is achieved, so an abnormal image in a road is observed.
