The invention relates to the technical field of numerical
simulation analysis, in particular to a typical structure identification method, device and equipment, a storage medium and a program product. Comprising the following steps: acquiring a three-dimensional particle
point set of a to-be-identified target, and calculating
porosity, a direction characteristic value, overall
linearity, overall flatness and spherical degree based on the three-dimensional particle
point set; judging whether the to-be-identified target belongs to a first typical category set, a second typical category set or a third typical category set based on the
porosity; when the to-be-identified target belongs to the first typical category set, identifying the typical structure of the to-be-identified target based on the
porosity; when the to-be-recognized target belongs to the second typical category set, recognizing the typical structure of the to-be-recognized target based on the
sphericity; and when the to-be-identified target belongs to the third typical category set, the typical structure of the to-be-identified target is identified based on the direction characteristic value, the overall
linearity and the overall flatness, and the efficiency of
structure type identification and
space debris impact spacecraft risk
simulation evaluation can be effectively improved.
