Training method and system for violence and terrorism tool and gun detection model and computer storage medium

The invention discloses a violence and terrorism tool gun detection model training method and system and a computer storage medium. The method comprises the following steps: acquiring a violence and terrorism toolgun picture set, and marking position and category information of the violence and terrorism toolgun picture set in a small batch; after labeling, dividing into a training set, a verification set and a test set; performing data enhancement on the training set; the method comprises the following steps of: adding a feature map pyramid network on a hierarchical vision (swing-transfer) feature extraction network to obtain an updated swing-transfer feature extraction network, performing model training on a training set after data enhancement on the updated network, and performing testing through a verification set and a test set to obtain the accuracy rate and the recall rate of the test set, so that the accuracy rate and the recall rate of the test set are improved. And when the two values are greater th
