Abstract: In recent years, with the continuous development of computer graphics technology and the wide application of artificial intelligence technology, three-dimensional human modelling technology based on artificial intelligence has gradually become a research hotspot. This article aims to use artificial intelligence to optimise the design of the system. The article introduces common 3D human modelling methods, and then optimises the 3D human reconstruction algorithm. Then, it elaborates on the process of generating complex virtual scenes and 3D facial modelling methods, and uses sequence images to achieve 3D human model reconstruction. Finally, a detailed analysis is conducted on the construction of a character expression action generation system. The experimental results show that the three-dimensional human body reconstruction algorithm designed in this paper reduces the time consumption by about 50% compared to traditional algorithms, and the error is reduced by about 30% compared to traditional algorithms.

Keywords: virtual reality technology; 3D virtual human; model construction; character expression action system; artificial intelligence.
