BIM+AR in Architecture: A Building Maintenance Application for a Smart Phone

Revit, 3ds Max, Unity 3D, and other software were used as experiments to model the elements in the wall based on the AR foundation and matching existing models with real-world architecture. Different from the tracking location method in other research, a start location was created to make it easier to match the digital with the real world. Then, users can click to choose the wall, the floor or the roof and hide it to show the inside components. And the components can also be moved by the button on device to realize the human-computer interaction. In addition to AR imaging, a demonstration animation was added to show the optimal disassembly method of a complex structure group or complex components in the wall.
