Abstract:
1. A work implement tracking system comprising: a work implement; a target secured to the work implement; at least one camera configured to acquire one or more images of the target; and a processor coupled to the camera wherein the processor executes a vision recognition algorithm to process the acquired images of the target to determine one or more positions of the work implement during performance of a task and the processor executes a vision tracking algorithm on at least one of the acquired images to determine work implement information, wherein the vision tracking algorithm when executed by the processor generates extremum information associated with the target by cross-correlating at least one structure across at least a portion of the image, wherein the extremum information includes at least one coordinate point associated with cross-correlating the at least one structure across the acquired image; extracts at least one icon from the acquired image, wherein the icon includes the coordinate point associated with the extremum information; determines an angle associated with the at least one icon; normalizes the icon to a fixed size; and stores the icon information in a computer readable form, wherein the icon information includes image values associated with at least a portion of the icon; the at least one coordinate point associated with the extremum information; and the angle associated with the at least one icon.
