T218　potted　flower　transplanting　machine　has　completed　the　transplanting　operation　of　the　Anthurium　from　small　to　big　flowerpots　in　greenhouse.　However,　the　Anthurium　stems　prepared　for　transplanting　that　deviated　from　the　center　of　the　small　flowerpots,　resulted　in　eccentric　growing　of　the　Anthurium　in　large　flowerpots.　To　solve　the　problem　above,　the　self-aligning　soil　build　and　cavitation　system　for　eccentric　Anthurium　stems　was　designed　based　upon　machine　vision.　And　the　visual　inspection　system　of　eccentric　flower　seedling　was　constructed　correspondingly,　in　which　the　OSTU　method　was　used　for　gray　image　threshold　segmentation　of　Anthurium　seedlings　to　get　binary　images.　The　feature　extracted　is　carried　out　with　the　target　of　eccentricity.　According　to　the　eccentricity　inspected　in　X-axis　and　Y-axis　direction,　the　soil　build　and　cavitation　system　was　designed　and　automatically　adjustment　movement　of　the　large　flowerpots　was　achieved　in　horizontal　and　vertical　directions.　A　large　number　of　experiments　showed　that　self-aligning　soil　build　and　cavitation　system,　which　showed　good　results,　has　successfully　solved　the　eccentric　problem　of　Anthurium　stems　after　being　transplanted　to　the　big　flowerpots.　©　2018　IEEE.
