Automatic Classification of Cabbage Seedlings for Spring Cabbage Production

Abstract

Seedlings grown up in a open field are utilized on spring cabbage production in Kanagawa Pref. Then sorting the seedlings into several ages or sizes is indispensable because the seedling age and its size are not uniform. High correlation coefficient between the seedling ages and total length of cabbage seedlings was observed. We have developed two kinds of measuring instruments for sorting cabbage seedlings. The means of an electrostatic capacitance instrument using parallelplate condenser was able to classify cabbage seedlings into several length. And the seedling size measuring device using infrared sensors was also able to classify them with accuracy.
