UNCERTAINTY DISPLAY FOR A MULTI-DIMENSIONAL MESH

Abstract:

In various example embodiments, techniques are provided for representing uncertainty when displaying a rendered view of a multi-dimensional mesh (e.g., created by SfM photogrammetry) in a user interface by applying a real-time, obfuscation filter that modifies the rendered view based on uncertainty in screen space. Where the multi-dimensional mesh is within a limit of data accuracy, the rendered view is shown without modification (i.e. as normal), and a user may trust the information displayed. Where the multi-dimensional mesh is beyond the limit of data accuracy, the obfuscation filter obfuscates detail (e.g., by blurring, pixilating, edge enforcing, etc.) in the rendered view so that a user may visually perceive the uncertainty. The amount of obfuscation may be weighted based on uncertainty to allow the user to visually quantify uncertainty.
