In this study, It takes the selection of tomato fruit appearance acquisition equipment as the key point, combined with the fruit shape extraction algorithm, discussing the establishment of the model of tomato. It is very necessary to design and simulate the life process and production process of tomato by using digital technology and constructing digital tomato technology system. At the same time, it explained the model's process design and function of the simulation system, based on the introduction of the morphological development of tomato. Tomato is one of the most common fruits and vegetables that are cultivated in the world.
