Claim One:
1. A system for performing three dimensional, stereo measurement, the system comprising: a sensor for obtaining a sensor image of a scene; a database for providing first and second reference images of the scene that are a stereo pair of images; at least one processing system responsive to an output of the sensor and in communication with the database, and operable to: register the sensor image with the first reference image; select a point of interest from the sensor image; derive a point of interest in the first reference image from a selected point of interest in the sensor image and a registration between the sensor image and the first reference image; perform a stereo point measurement from the selected point of interest and the first reference image to determine a point in the second reference image that represents a stereo mate of the selected point in the first reference image; and modify the stereo point measurement using stereo evaluation to select an adjacent three dimensional point which more accurately corresponds with the selected point in the sensor image; wherein said three dimensional stereo measurement of the selected point of interest in the sensor image is in scene coordinates.
