1. A method of gauging entities in an image comprising the steps of:

  • constructing a model data structure;

    identifying a set of gauge entities in said model;

    automatically configuring sub-models according to the stability of features in said sub-models for computing position of each of said gauge entities by;

    defining a set of regions for each gauge entity;

    assessing each region for stable reference features;

    selecting a best region for each gauge entity; and

    training a sub-model representing each feature that exceeds a predetermined stability threshold within each of said best regions;

    locating said sub-models in said image;

    computing positions of each of said gauge entities by reference to locations of located sub-models; and

    determining the spatial relationship between said gauge entities.
