| Abstract: | The kiwifruit automatic grading machine is an important machine for postharvest processing of kiwifruit. A set of practical automatic kiwi fruit grading machine was designed based on technologies of mechanical separation and conveyance, image capture and processing as well as intelligent control. This set of equipment mainly consisted of material storage bin, single line positioning system, image capture system and grading executive system. And it also has programs of image capture, image processing, grade determination and human-machine interaction for the host computer as well as control programs for the slave computer. By testing, this machine was capable of grading by three features of size, shape and surface defect and their grading accuracy could reach to 88.9%, 91% and 94%, respectively. And the accuracy of integrated grading could reach to 86%. |
