Abstract
A method for determining a shape of a substantially cylindrical specular reflective surface includes the step of obtaining calibration data and the step of obtaining target data about a target structure. The method further includes the step of defining a target line from the target data, where the target line represents a feature of the target structure and the step of capturing a reflected image of the target structure in the specular reflective surface. The method further includes the step of obtaining reflected data from the reflected image and the step of defining a reflected line from the reflected data, where the reflected line represents a reflection of the feature of the target structure. The method also includes the step of determining a correspondence between the target line and the reflected line and using the correspondence and the calibration data to determine the shape of the specular reflective surface.
