Development of a Yield Monitor for Citrus Fruits
نویسندگان
چکیده
A method to measure the per-tree yield of citrus fruits was developed based on three approaches. Initially, the problem was viewed as a variation on the theme of particle counting as performed earlier on flows of fertilizer particles. The main difference was that 1) citrus fruits are much larger than fertilizer particles 2) they travel at a significantly lower speeds an 3) their flow density may be higher than that of fertilizer.

Bioactive components play an important role in human health. In general, bioactive compounds of fruits decline during storage. Therefore, maintaining fruits bioactive compounds during storage is very important. In this study, effects of pre-harvest CaCl2 sprays (0, 1, 2, and 4%) at different fruit development stages (120, 140, and 160 days after full bloom) on maintaining fruit quality of thre...

In this paper, we present a technique to estimate citrus fruit yield from the tree images. Manually counting the fruit for yield estimation for marketing and other managerial tasks is time consuming and requires human resources, which do not always come cheap. Different approaches have been used for the said purpose, yet separation of fruit from its background poses challenges, and renders the ...
