Patent ID: 7006086

Claim:
A digital imaging system comprising: A. a scene illumination arrangement configured to illuminate said scene comprising at least one object and at least one target independent of said at least one object, said at least one object and at least one target capable of being illuminated, the scene illumination arrangement being configured to illuminate at least the at least one object and at least one target to facilitate disambiguation between the at least one object and the at least one target; B. an image recording device configured to record at least one image of a scene when said scene is illuminated by said illumination arrangement, C. an image processing subsystem configured to process the at least one image to differentiate a part of said image corresponding to said at least one target from another part of said image corresponding to said at least one object in said at least one image and to identify a location of the at least one target appearing in the at least one image with respect to a local coordinate system associated with the location from which the image recording device recorded the at least one image of the scene, and for relating said local coordinate system to a global coordinate system, wherein the location of the said at least one target with respect to said global coordinate system is known independently of said at least one image.
