Foundation meteorological cloud picture classification method based on cross validation deep CNN feature integration

Abstract

The invention belongs to the technical field of ground-based meteorological cloud picture classification, and particularly relates to a ground-based meteorological cloud picture classification methodbased on cross validation deep CNN feature integration. According to the method, firstly, a convolutional neural network model is utilized to extract deep CNN features of a foundation meteorological cloud image, then multiple times of resampling of the CNN features is performed based on cross validation, and finally, identification of the cloud shape of the foundation cloud image is performed based on a voting strategy of multiple times of cross validation resampling results. According to the method, the ground-based meteorological cloud images are automatically classified, and an adaptive end-to-end automatic cloud recognition algorithm directly based on the original cloud images without any image preprocessing is realized. The proposed algorithm relates to the fields of computer vision,machine learning, image recognition and the like. The proposed algorithm fully overcomes the non-robustness of a single CNN feature cloud classification result and the high calculation overhead of multi-time deep convolutional neural network integration, and at the same time, ensures that the proposed algorithm has high classification accuracy and noise stability.
