Abstract

Modern smartphones provide an excellent platform for creating 3D scenes from photos. While there already exists many mobile applications that can stitch a set of photos to create a single, panoramic landscape photo, this paper proposes the creation of panoramic scenes where multiple photos are projected in a 3D space using the pinhole camera model, so that a realistic perspective of the scene is maintained. Our application allows users to automatically create a panoramic 3D scene in real-time using the live images from the phone's camera, and to manually fine-tune each photo's position via the touchscreen if the default position is inaccurate. The application enables scenes to be easily shared to other users, and was developed using the Silverlight framework so that it can run across multiple platforms.
