The invention discloses a main hull large grillage topology modeling method based on two-dimensional identification strategy three-dimensional linkage, which comprises the following steps: S1, determining a main hull large grillage area needing to be established, and checking information in a hull basic structure diagram and a middle cross section diagram; s2, according to the definition of a main hull large grillage, hull drawing objects are classified and judged to be divided into hull plates, profiles and marks; s3, extracting different object types in the two-dimensional drawing according to the optimized two-dimensional recognition strategy; s4, according to a topology driving rule, carrying out block reference primitive identification to obtain parameter information of a ship body plate, and forming a rule-driven modeling frequency; and S5, outputting the data information in the step S3 and the step S4 to an Excel data source file to realize data source visualization and user-defined modification and updating. According to the method, the two-dimensional and three-dimensional linkage technology is applied, and efficient, accurate and automatic creation of the main hull large grillage under multiple scenes is achieved.
