Abstract: In view of the problems of low efficiency, low accuracy, and assembling quality and
reliability are difficult to guarantee which caused by the traditional cable simulation assembly
experimental method based on physical prototype, this paper proposes an assembly method of cable
harness under virtual and real scene fusion for complex mechatronic products. Firstly, we analyze the
advantages of the augmented reality technology applied in the cable harness assembly, and construct the
assembly system of cable harness under virtual and real scene fusion based on augmented reality.
Secondly, we introduce the key technologies involved to the above assembly system, and elaborate the
technologies of cable harness 3D registration, cable harness occlusion, cable harness illumination, and
camera calibration and tracking. Finally, we introduce the research contents and give the assembly
system running process of cable harness under virtual and real scene fusion based on augmented reality.

Key words: cable harness virtual assembly, augmented reality, architecture, complex mechatronic products
