Study on the Plant Factory Automatic Control System according to Each Crop Growth Step

There is a case growth disorder is caused by different environmental condition according to each growth step in crops. However, the existing systems control the growth environment of crops without considering the growth step of crops. This paper proposes a plant factory automatic control system according to each crop growth step, which can measure the growth step of crops by utilizing a digital image processing technique and can provide crop growth environment and service suitable for crop growth step. The proposed system collects crop image information through 2 CCD cameras installed in the plant factory, and converts it into binary image, and then estimates crop growth step, and provides crop environment control and service suitable for crop growth step.
