Research and Implementation of an Augmented Assembly System Based on Markers

The traditional virtual assembly technology requires building a true three-dimensional scene of all the assembly data, leading to complex modeling, low sense of reality and efficiency of real-time interaction. An augmented assembly system based on markers is proposed. The camera calibration technique is studied to get its inside and outside parameters first; a 3D registration algorithm based on markers is used to determine the exact location of virtual objects in the real scene then; the augmented assembly system is constructed according to the characteristics of virtual assembly finally. Experimental results show that the augmented reality technology makes the assembly steps appear in front of the staff intuitively and allows them to complete the actual assembly correctly, improving the sense of reality of the operation and interaction efficiency.
