Abstract: A method and system for determining the angular position of an object are disclosed. As one example, a method for determining the angular position of an object is disclosed, which includes the steps of obtaining data representing an image of a surface area of the object, the image including a plurality of dots, determining a set of coordinates for each dot of the plurality of dots, selecting a predetermined number of dots of the plurality of dots, comparing the predetermined number of dots with a plurality of dots stored in a dot map, responsive to the comparing step, if the predetermined number of dots substantially match the plurality of dots stored in the dot map, selecting the predetermined number of dots, and forming a coordinate transformation matrix representing a transformation from a coordinate frame associated with a position of the predetermined number of dots at the surface of the object to a coordinate frame associated with a position of the image of the surface area of the object.

Abstract: A method for enhancing the accuracy of a sensor is provided. The method includes determining a measure of the output of the sensor, determining whether the measure falls outside of an acceptable range for the output of the sensor, and, when the measure falls outside the acceptable range, modifying the measure of the output such that the measure falls within the acceptable range for the sensor.
