Research On Construction Technology Of Augmented Reality Maintenance Guiding System

Augmented Reality(AR) is a new and promising research field. In an AR system, a user's view of the real world is enhanced or augmented with additional information generated from a computer model. In domestic, we start to study AR so late, and few people have made achievements. Especially, there is still blank about the AR study or applications in the domain of aviation manufacture and maintenance。Now, the airplane maintenance is depended on the paper document or electrical document, people should look for the documents when they are operating. It will be affected by the environment easily and some mistakes will appear. And the quality will be poor when the operations are depended on the operator's skills only. Innovation of the aero maintenance system based on Augmented Reality(AR) technology and eye tracking technology ,which can give real-time instruction for maintenance, is vital for enhancing the accuracy of maintenance and reducing the cost of maintenance.In the paper , the study work include 3 sections, as following : Firstly, deducing 3D registration algorithm based on markers, depicting the display and 3D display technologies of artificial matters, and realizing 3D registration function specifically; Secondly, establishing an eye-movement measurement system based on the infrared television method, making use of the thoughts of ranks superimposition to withdraw the pupil center coordinates, and giving the thaught of recombining the position relation of Purkinje spot to determine the eye sight direction primarily; Finally, describing the basic theory of augmented reality maintenance guiding system in detail, and introducing the software function and hardware frame, which will provide the foundation for the further study of this system.
