Abstract

Disclosed herein is an assembly process visualization apparatus. The assembly process visualization apparatus includes an authoring unit, a storage unit, and a visualization unit. The authoring unit authors an assembly process manual in such a way as to model each stage of an assembly process of assembling a plurality of components and completing a finished product using 3-Dimensional (3D) stereoscopic images. The storage unit stores the assembly process manual authored using the authoring unit. The visualization unit visualizes the each stage of the assembly process manual stored in the storage unit to a user.
