| Outline of Final Research Achievements |
Aiming at effective plant management of a strawberry production using a movable bench system, we developed a non-destructive sensing system which gets growth information of strawberry plant community as well as fruit information (number and size). Image processing algorithm was designed to extract these features from color and depth images.
Analyzing the reconstructed three dimensional data from plant community, plant height and width could be estimated at arbitrary profile. Chronological change of size of the plant community had been observed for two and a half months. Consequently it was revealed that the predicted growth data had a high correlation with the actual data. Regarding to fruit imformation, an accuracy for counting mature fruits reached approximately 95% using the depth information even in the condition of high fruit-density in a planting bed. Furthermore, RMS percentage error of the size estimation was 12%.
