Google Street View provides impressive photorealistic views of various spots worldwide and allows users to explore scenes without being there physically. The generation of such virtual walkthroughs, however, requires sophisticated recording devices and is not feasible for end-users easily.
The goal of this work is the development of a prototype application enabling users to create their own virtual walkthroughs with conventional smartphones. The thesis therefore mainly focuses on the development of a mobile visual odometry system that serves as basic technology for such photo tour application. The odometry system reconstructs the motion of the user both indoors and outdoors, in real-time with three degrees of freedom and with adequate accuracy. Combined with a technology for automatic panoramic image stitching, users can eventually navigate between captured waypoints, generating the impression of virtually moving through the captured scene.
