b6, dividing the plugboard (20) into square grids according to the number of the transverse conductive adhesive tapes (22) and the longitudinal conductive adhesive tapes (23), and acquiring grid numbers of the central positions of each real drawing pin area;

in B3, the threshold range is set according to the following steps:

b31, inserting a plurality of drawing pins (10) at any position on the inserting plate (20);

b32, shooting the front image of the plugboard (20) and performing trapezoidal correction;

b33, manually marking a pin area in the RGB after the trapezoidal correction;

b34, calculating a threshold value range according to the R, G, B value of each pixel of the marked pushpin area { [ R ]_MIN,R_MAX],[G_MIN,G_MAX],[B_MIN,B_MAX]80% -95% of the pixels have R, G, B values within a threshold range;

in B3, the pixel point of R, G, B value in the corrected RGB image within the threshold range is marked as 1, and the pixel point outside the threshold range is marked as 0.
