In-situ flood visualisation using mobile AR

We present a prototype augmented reality (AR) app for flood visualisation using techniques of in situ geometry modeling and constructive solid geometry (CSG). Natural and augmented point correspondences are computed using a method of interactive triangulation. Prototype geometry is oriented to pairs of triangulated points to model buildings and other structures within the scene. A CSG difference operation between a plane and the geometry produces the virtual flood plane, which can be translated vertically. Registration and tracking is achieved using the Qualcomm Vuforia software development kit (SDK). Focus is given to the means with which the objective is achieved using readily available technology.
