An Interactive Indoor 3D Reconstruction Method Based on Conformal Geometry Algebra

This paper presents an approach for indoor reconstruction using smartphones. The smartphones sensors are used for measuring the azimuth angle and pitch angle. With these angles, the rooms of the indoor scene are effectively reconstructed. Then the separately reconstructed models are aligned together to form a complete model. Meanwhile, the conformal geometry algebra is used as computing framework. Comparing to other reconstruction approaches, the use of conformal geometry algebra not only simplifies the construction of geometry, but also unifies the representation of all kinds of geometry relations. Remarkably the proposed approach does not need to take photos during the reconstruction process, and it requires only a little clicking on the developed mobile application to build the model. To verify the proposed approach, a typical apartment was chosen as experiment environment. Result from the experiment suggests that the proposed approach is very efficient and suitable for mobile platform.
