The invention discloses an electronic device, a picture sample set generation method and a computer readable storage medium. The picture sample set generation method comprises the steps that pre-recorded videos are played one by one; for each frame of picture, the frame of picture is subjected to identification and marking processing; after all the videos are played, a document folder is created correspondingly for each mark, and all the pictures are stored in the corresponding document folders according to the marks; for each document folder, a pre-trained deep learning model of face recognition is used for performing feature extraction on all the pictures in each document folder to obtain the feature vectors of the pictures in each document folder; clustering processing is performed on the feature vectors in the document folders by a clustering algorithm to clean and remove impurity pictures in the document folders; and the pictures in all the document folders are merged to form a picture sample set. According to the technical scheme, the picture sample set with fewer impurities is quickly generated through video resources, and the models trained by a training set have a better effect.
