Virtual human quick modeling method oriented to field of ship virtual reality

Abstract

The invention discloses a virtual human quick modeling method oriented to the ship virtual reality field. The method comprises the following steps: 1), determining a needed module according to the modeling demands of a customized virtual human; 2) judging whether each module in the model database meets a modeling requirement or not; 3) determining modules required for virtual human modeling and lacking in the model library, and judging whether a module with reference value exists or not; 4) performing parameter modification modeling on the module with the reference value; 5) performing model reconstruction on the missing modules without reference values; 6) performing quick combined modeling on the modules meeting the customization requirements to generate a virtual human model; accordingto the virtual human modeling method, a virtual human modeling mode combining modular modeling, parametric modeling and personalized feature modeling is adopted, technicians are liberated from bottomlayer model wiring modeling work, the modeling period is shortened, and the modeling workload and cost are reduced.

Description

technical field [0001] The invention relates to virtual reality technology, in particular to a virtual human rapid modeling method oriented to the field of ship virtual reality. Background technique [0002] With the increasing application depth and breadth of virtual reality technology in the shipbuilding field, the shipbuilding engineering field has put forward a large number of demands for advanced customization and personalized design of virtual humans with different roles. The virtual human in the ship field has the characteristics of high degree of customization, good uniform uniformity, large group, and different body sizes. [0003] The conventional virtual human modeling method is: according to the customization requirements, carry out the modeling from the bottom up in the 3D software (such as 3ds max). The modeling cycle is long, the workload is heavy, the modeling cost is high, and the software operation skills of technicians are extremely demanding. [0004] T...

Problems solved by technology

[0005] (1) Human body 3D scanning modeling involves expensive scanning equipment, low recognizability of scanning data, and difficult data analysis and processing technology, which is not suitable for large-scale application and promotion

[0006] (2) The image-based virtual human construction method has too high requirements on the professional level of image and technical personnel, and is not suitable for ordinary modelers to operate and apply

[0007] (3) The existing parametric modeling of the human body can realize virtual human modeling with different size parameters, but it can only be modeled with variable parameters on the basis of a given human body model, which obviously cannot meet the needs of multiple application scenarios for virtual human characters, clothing , model texture and other aspects of personalized modeling requirements
