A new grid subdivision method in the application of 3D seismic tomography

Based on travel-time linear interpolation, an improved mesh subdivision method is presented in this paper, which can obtain higher accuracy with less computation cost based on solving the three-dimensional LTI minimum travel-time problem. The paper gives the algorithm principle and calculation steps. It verifies the improvement of the new algorithm in calculation accuracy and efficiency through calculation examples.
