Abrégé
(EN)
The invention discloses an object detection model training method and device, computer equipment and a storage medium, and relates to the field of artificial intelligence. The object detection model training method comprises the steps of obtaining a training sample; inputting the training sample into an object detection model for model training, the object detection model comprising a detection module, a classification module and a discrimination module; obtaining the detection loss generated by the detection module, the classification loss generated by the classification module and the judgment loss generated by the judgment module in the model training process; and updating the object detection model according to the detection loss, the classification loss and the judgment loss to obtaina target object detection model. The target object detection model trained by the object detection model training method can effectively improve the object detection accuracy.
