Abstract: The present application relates to a method, apparatus and system for recognizing a tremor symptom, a recognition terminal and a storage medium. The method includes: receiving an image to be recognized which is uploaded by a user terminal, where the image to be recognized includes spiral graph used for recognizing whether a drawing person has a tremor state or not and evaluating a tremor level; and taking the image to be recognized as an input value of a pre-trained convolutional neural network regression device to obtain a tremor level. By using the method, the tremor can be recognized by means of images, which is non-invasive and patient-friendly, and since a model is a deep learning algorithm trained on a large spiral image dataset, results of evaluating the severity of essential tremor are accurate and consistent.
