The application provides a ground penetrating radar data inversion method and device, computer equipment and a storage medium, comprising: receiving ground penetrating radar data; calling a preset one-stage network model to perform inversion operation on the ground penetrating radar data to obtain a first dielectric constant model; calling a preset two-stage network model to perform inversion operation on the ground penetrating radar data and the first dielectric constant model to obtain a second dielectric constant model. The application ensures the accuracy of the first dielectric constant model, modifies the incorrect structural features in the first dielectric constant model, and obtains a more accurate second dielectric constant model, greatly improves the operation efficiency of ground penetrating radar data inversion, and reduces the consumption of computing resources.
