CCD visual automatic positioning method

The invention discloses a CCD visual automatic positioning method. The method specifically comprises the following steps that S1, a product to be positioned is placed on a feeding section of automatic positioning equipment; s2, centering plate beating and mechanical positioning are conducted through automatic positioning equipment; s3, scanning the two-dimensional code on the product flow sheet by a code scanning gun; s4, after the control system reads the information, a host computer of the control system automatically interprets the information, and after mechanical positioning is carried out according to the two-dimensional code information, the interpreted target point coordinate information is sent to an alignment system; s5, the alignment system performs automatic positioning according to the coordinates of the target spot, and performs storage after automatic learning; and S6, CCD visual automatic positioning is completed, and the automatic positioning equipment enters a full-automatic process.
