If the position movement distance of a certain joint point or the moving speed of a certain footstep of a certain action of the virtual digital human role model using the user's needs is not within the position movement distance compliance interval of a certain joint point of a certain action or the moving speed compliance interval of a certain footstep, then the action compliance index of the virtual digital human role model using the user's needs is recorded as , otherwise it is recorded as , and then get the virtual digital human's action matching index of Tujia cotton weaving sacrificial ceremony , The values include or , > .

9. The virtual digital human character precision modeling system based on the Tujia brocade cultural gene map according to claim 1 is characterized in that: The specific analysis method for judging whether the virtual digital human role model is suitable for the needs of the user is as follows: Based on the obtained scenario adaptation index of the virtual digital human role model of the user's needs, the scenario adaptation index of the virtual digital human role model of the user's needs is compared with the scenario adaptation index safety range of the virtual digital human role model of the user's needs stored in the database. If the scenario adaptation index of the virtual digital human role model of the user's needs is not within the scenario adaptation index safety range of the virtual digital human role model of the user's needs, it means that the virtual digital human role model of the user's needs is not compatible. According to the pattern set, color set and action sequence set of Tujia brocade in various usage scenarios, the visual distortion and action jamming problems in the operation process are recorded, and the virtual digital human role model is regenerated.

10. A method for executing the virtual digital human character precise modeling system based on the Tujia brocade cultural gene map according to any one of claims 1 to 9, characterized in that: include: Step 1: Data acquisition: Based on the cultural gene map of Tujia brocade, extract the pattern set, color set, and action sequence set of Tujia brocade in various usage scenarios; Step 2: Virtual Digital Human Character Creation: Based on the virtual digital human character creation goals uploaded by the user, a virtual digital human character model is adaptively generated to meet the user's needs; Step 3: Virtual Digital Human Role Analysis: Based on the generated virtual digital human role model based on the needs of the user, evaluate the functional compliance index of the virtual digital human role model based on the needs of the user; Step 4: Feedback judgment: Based on the obtained functional compliance index of the virtual digital human role model of the user's needs, the created virtual digital human role model of the user's needs is functionally tested to determine whether the virtual digital human role model of the user's needs is abnormal. If it is abnormal, an abnormality report is generated and re-created.
