Small chrysanthemums are a major type of cut flower used in Japan for which we are developing flowering stage inspection equipment. This equipment has a camera and a flower carrier. When a flower is input to equipment, the equipment captures the flower image from the zenith, recognizes the flower and leaf parts in the image, determines whether it is appropriate for shipping, and drops it into the appropriate output area. Considering usability, equipment is designed to be attached to the weight grading equipment widely used by growers of small chrysanthemums. In this paper, we introduce this equipment and the results of evaluation experiments.
