Abstract
This study carried out to develope the vision system which automatically finds out a optimum transferring period of plants (Perilla, Platycodon grandifloums and Lactuca sativa) by using image process-ing. This system mearsured a height, long diameter and short diameter of the three plants with 20 replications. Following results were obtained on each plant. Compared with real data to be measured by hand with the vernier calipers, height, long diameter and short diameter of Perilla showed 0.5 mm average error rate with 1.7%, 4.7 mm average error rate with 3.9% and 5.5 mm average error rate with 6.9% respectively. Those of Platycodon grandifloums showed 2.4 mm with 8.1%, 3.4 mm with 7.2% and 4.0 mm with 10.4% respectively. Those of Lactuca sativa showed 4.0 mm with 9.1 %,3.4 mm with 7.2% and 3.6 mm with 9.4% respectively. The system could be used to transfer accurately the plant seedling, if the system were improved enough to reduce error rate for the optimum transferring period of a plant in the greenhouse.
