Automatic alignment method and device based on image recognition technology for manipulator

The invention discloses an automatic alignment method and device based on image recognition technology for manipulator. The automatic alignment method includes establishing an XY coordinate system of the manipulator relative to a prospective area in a direction of a fixed die in advance; acquiring XY coordinates of the manipulator relative to the prospective area; making a mark at the center position of the side, facing the corresponding moving die, of the fixed die of each die; acquiring fixed die images in the prospective area after mounting of the fixed die; analyzing XY coordinates of the maker relative to the prospective area from the acquired images; and regulating position of XY coordinates of the manipulator corresponding to the marker according to the coordinates of the maker relative to the XY coordinate system on the basis of analysis result, thereby aligning the manipulator with the maker. The alignment device comprises a coordinate system establishing module, a manipulator coordinate acquisition module, an image acquisition module, an analysis module and a manipulator regulating module. By the automatic alignment method and device, work efficiency of work staff in regulating the manipulator is improved while personal safety of the work staff is enhanced.
