Abstract: The diversity of virtual humanfor simulation is mainly exhibited by the character. The
differences between models consist of two parts: the somatotype and the head accessories. Automatic
matching head accessories for virtual human will observably increase the realistic of the simulation. A
new method for automatic matching is presented. Firstly, we assign simple skeleton to the accessories
and choose anchor points after automatic rigging skeleton for virtual models, then execute the matching
method to achieve matched model. Finally, we assign various postures to the model by embedskeleton.
The result shows our method can match the head attachments to diverse virtual human automatically,
and pretty improve the diversification of virtual models.

Key words: head accessory, automatic matching, virtual human, automatic rigging skeleton
