Kind Code:
B2
Abstract:
PURPOSE:To raise a position accuracy of a feature point after visual recognition by deriving a lattice point position estimated from a circumferential distribution of a lattice video to correct-process an inputted value to the lattice center position, in case of inputting a coordinate position by using a cursor, etc. CONSTITUTION:When a drawing is mounted to a drum 2 to recognize the drawing, correcting data of an inclination angle theta which the drawing 1 has with respect to drum references D1, D2, and the coordintes O1-O4 reference of the drawing are inputted. The processings for estimating the lattice center position from the circumferential distribution of a lattice picture of areas S11-S14, S21- S24 and S31-S34 around the three designated reference positions O1-O3, and for correcting a value inputted by a cursor 12 to the lattice center position are executed respectively. Accordingly, when a difference between an input position of a reference point of the drawing inputted by use of the cursor 12, etc., and the lattice center position to be inputted originally having a printed gap G on the drawing form 1 is G/2 or below, the value can be corrected automatically to the lattice center position.
