  • Method, apparatus and system for calculating stress parameters and computer device
    Patent number: 11481894
    Abstract: A method, apparatus and system for calculating stress parameters is provided. The method comprises establishing a first image pyramid according to an image of a sample before deformation, and establishing a second image pyramid corresponding to the first image pyramid according to an image of the sample after deformation; starting from a top level in the first image pyramid, iteratively calculating displacement information on each level in the first image pyramid relative to a corresponding level in the second image pyramid based on a center point of each sub-region at each level in the first image pyramid and other positions in the sub-region; calculating strain information on the sample according to displacement information on a bottom level of the first image pyramid; and calculating stress parameters of the sample based on the strain information.
