Equipment Maintenance Based On Augmented Reality System Design And Implementation

Augmented Reality (AR), arising from the early of 1990s, is a recently research hotspot, which is combined with Computer Graphics, Image Processing, Human-Computer Interaction, Sensor Technology. Augmented Reality systems add virtual computer-generated material to the surrounding physical world to improve the person's perception. As the person moves about, the position and orientation of his or her head is tracked, allowing the overlaid material, such as graphic, image, sound and so on, which is generated from the computer, to remain tied to the physical world.The topic explored the technical realization of equipment maintenance systems based on Augmented Reality and application models in the field of equipment maintenance. According to the fundamental characteristics of Augmented Reality and the operation of the system theory, this thesis has analysed the system functions and performance requirements, discussed the framework of the system, which included the hardware and the software configuration theory, expounded the related algorithms and the operation processes of the system, achieved the GUI design and a prototype, and finally made the experiment of the prototype and obtained the preliminary results. During the realization of the prototype, it collects the video of real scenes firstly, identifies the Markers in the video images to obtain the information of them, calibrates the camera parameter based on the Markers'information, registers the virtual scenes and real world to obtain the relationship matrix of them, and finally realizes the blending of the virtual scenes and the real scenes.This thesis has explored the related issues of the equipment maintenance system based Augmented Reality, and preliminarily realized the prototype system, which provides a initial experiment platform and strong reference for the deeper and wider research in future.
