Abstract: Aiming at the assembly guidance in augmented reality environment, an uniform
augmented-assembly-oriented information model is build to manage visual text, geometric and
feature information during assembly process in augmented reality environment. A marker-based
tracking is adopted to realize the registration and localization of virtual and physical product part. The
depth images of both virtual and physical scenes are used to handle occlusion between virtual and real
objects in assembly process. The assembly guidance information is superimposed on the real time
assembly video by using registration information of parts. A demonstration system is developed and
the assembly guidance process is analyzed and described in augmented reality environment.

Key words: computer application, augmented reality, assembly guidance, marker based
registration, information superimposition
