An image processing algorithm is adopted, the positions of the main stems and the lateral branches of the tomato plants can be automatically recognized, excessive manual participation is not needed, the working efficiency and accuracy are improved, and convenience is provided for obtaining the position information of the lateral branches of the tomatoes.
