Development of Aligning Seeder for Big and Elliptical Seeds (Part 2)

A Seeder Equipped with Image Processing System

Abstract

This report introduces a seeder that accommodates cucurbitaceous rootstock seeds and can arrange the direction of longitudinal axis and germ pore using an image-processing system.
The side of the germ pore was determined by comparing the width of each seed. This algorithm could clearly recognize the side of the germ pore with an accuracy exceeding 99% and required only 0.09s/seed.
The accuracy (one seed per cell, arranged along the longitudinal axis (±300) and the germ pore with fixed direction) was about 95% and capacity was more than 5000seeds/h. We concluded that this seeder can replace two or three workers.
