abstract:this paper designed a bag grain quantity recognition method, which was based on plane image recognition. used digital image processing technique for collected image sample from the scene of grain warehouse, in order to reduce the noise and make the object’s character highlighter. then made use of the growth method to the each closed pixel district of the picture, so as to carry on the pixel clustering and image segmentation. at last according to the value of corresponding geometric moment of this character to judge the identity of each grain bag, and made the classification of the surface each grain bag belonged to come true by the value of its eccentricity, so as to achieve the automatic identify of grain’s weight.......
