Visual model training method and device, equipment and storage medium

The embodiment of the invention discloses a target vision model training method and device, equipment and a storage medium. The target vision model training method comprises the following steps: acquiring a first sample image and a background image; obtaining a target image according to the first sample image, and placing the target image in the background image to obtain a second sample image; inputting each sample image into a to-be-trained model, so that the to-be-trained model predicts a corresponding prediction category according to the sample image; and determining a first loss value according to the target category and the prediction category, adjusting model parameters of the to-be-trained model according to the first loss value until a preset training stopping condition is met, and taking the trained to-be-trained model as a target visual model. According to the embodiment of the invention, the problem of low model performance caused by few sample data, difficulty in sample data acquisition and the like can be solved.
