Tomato cultivation in large-scale plant factories is expanding in Japan. It is therefore important to measure the leaf area and growth of tomato accurately in the plant factory for estimating the yield. In this study, the area of tomato leaves was measured using a three-dimensional range meter. The models, which estimated the whole area of the tomato plant, were then developed using the area of a part of non-destructively measured leaf. The parameter necessary for the modeling was designed by taking the leaf position on tomato plant into account. As a result, a practical model for measuring the tomato leaf area non-destructively was developed.
