In view of screws counting problem in traditional warehouse management system
digital image processing is introduced to the detection and counting of screws. A method for screws automatic counting based on image processing ispresented.Processing the shelves without placing screws is to detect and record placed screw position information
establishing the template.In order to establish an accurate template
a way of human-computer interaction is proposed to correct
which can effectively solute the impact of light
noise
etc.Then unplaced screws image (template image) subtracts the detected image
standing out the features of placed screws. Finally
template matching is used to position the screws. Experimental results show that this method can effectively solve the impact of shelves damaged
screws oxidation and noise interference
and realizes simple. Counting accuracy rate of this method can achieve above 98%
