Machine Vision for Detecting Insects in Hole of Raspberry Fruit

Small living insects often attach in a raspberry hole, and Japanese customers hate them. Therefore farmers in Japan are manually checking all harvested raspberries and removing ones with insects before shipping them to fresh markets. It is difficult to find them even with human eyes. Such situation cause high cost and farmer's hard work on the cultivation. In this study, machine vision to detect insects in a hole of raspberry fruit automatically was developed for substitution of human manual work. As the result of the test, insects were identified with high success rate. Although there were several failure cases, it can be considered that they are improved by taking video inside a room with a stable artificial light.
