Abstract
A positioning method includes an imaging step, a straight line storage step, a straight line registration step, and a positioning step. The imaging step captures an image of a region including a target or street on a workpiece. The straight line storage step detects and stores the coordinate positions of all predetermined straight lines in the region. The straight line registration step allows an operator to select a specific straight line in the target or on the street from all the straight lines and register the selected straight line. The positioning step positions a processing unit on the street in accordance with coordinate data concerning the straight line selected and registered in the straight line registration step.
