AI summary

The present application provides a model training method, a target detection method and a device. In a model training phase, based on a first reference bounding box and its corresponding real bounding box and real category, a model to be trained is prompted to continuously learn a bounding box distribution and an identifying of a category of a target object; and determine a loss value based on a determination result set output by a determination sub-model, and then continuously update model parameters for multiple rounds of iterations based on the loss value, where the determination result set includes a first determination result that represents a bounding box distribution similarity, and a second determination result that represents a category similarity between the first prediction category and the real category.
