The method comprises the following steps: constructing an original data set; performing data enhancement on the original data set, and constructing a training data set, a verification data set and a test data set; performing size conversion and data normalization processing on the training data set; training parameters are set for the improved Deeplabv3 + model, a training data set and a verification data set are used for training and verification, and an optimal model is stored; and performing size conversion and data normalization processing on a to-be-identified image in the test data set, and inputting the to-be-identified image into the stored model to complete accurate segmentation of the tomato leaf insect pest area. The invention provides a new method for treating tomato insect pests, and effectively protects the growth of tomatoes.
