Abstract: The goal of this study was to develop the automatic thinner and weeding machine for the sugar beet. In this paper, the algorithm of distinction between sugar beet and weeds, which is necessary for the automatic thinner and the weeding machine was discussed. The distinction between the sugar beet and the weeds, the green amaranth, the wild buckwheat and the field horsetail, was tested using the shape characteristics of the leaf and the angle of the leaf tip portion based on the image processing technique. The results of the distinction indicated that the correct distinction rate of the sugar beet was 87.2% and the error rate was less than 8%.(Download PDF) (Export to EndNotes)
