The invention discloses a bearing fault diagnosis method, apparatus and device, and a readable storage medium. The method comprises the steps of obtaining signal data of a bearing in an operation process; performing matrix transformation processing on the signal data to obtain target data; inputting the target data to a diagnosis model to obtain a classification result; based on the classification result, determining the fault type of the bearing; the diagnosis model is obtained by performing iterative training on an image classification model based on a bearing signal training data set; the bearing signal training data set is obtained by performing matrix transformation processing on the signal data. According to the method, the signal data of the bearing in the operation process is subjected to transformation processing, so that the target data is obtained, the target data subjected to matrix transformation processing is used as the training sample, the diagnosis model is obtained through training, the clas
