In-situ refinement techniques for outdoor geo-referenced models using mobile AR

We present a set of techniques to perform in-situ refinements on simple geo-referenced models using mobile augmented reality systems. The refinements include affine transformations to the model and surface feature additions, including high detail concave and convex features. The techniques employ pinch gloves and a single-point laser rangefinder augmented with an orientation sensor as input devices. Finished models can be exported for use with other geospatial applications. The proposed techniques are intended to be an effective and elegant approach to enhancing outdoor models using mobile augmented reality.
